My application is running behind a corporate firewall and I need to use http proxy(http://theclientproxy.net:8080) to connect to internet
I have used the Netty client as below,
https://github.com/netty/netty/tree/4.1/example/src/main/java/io/netty/example/http/websocketx/client
Code:
public final class WebSocketClient {
static final String URL = System.getProperty("url", "wss://127.0.0.1:8080/websocket");
public static void main(String[] args) throws Exception {
URI uri = new URI(URL);
String scheme = uri.getScheme() == null? "ws" : uri.getScheme();
final String host = uri.getHost() == null? "127.0.0.1" : uri.getHost();
final int port;
final boolean ssl = "wss".equalsIgnoreCase(scheme);
final SslContext sslCtx;
if (ssl) {
sslCtx = SslContextBuilder.forClient()
.trustManager(InsecureTrustManagerFactory.INSTANCE).build();
} else {
sslCtx = null;
}
EventLoopGroup group = new NioEventLoopGroup();
try {
final WebSocketClientHandler handler =
new WebSocketClientHandler(
WebSocketClientHandshakerFactory.newHandshaker(
uri, WebSocketVersion.V13, null, true, new DefaultHttpHeaders()));
Bootstrap b = new Bootstrap();
b.group(group)
.channel(NioSocketChannel.class)
.handler(new ChannelInitializer<SocketChannel>() {
#Override
protected void initChannel(SocketChannel ch) {
ChannelPipeline p = ch.pipeline();
if (sslCtx != null) {
p.addFirst(new HttpProxyHandler(new InetSocketAddress("theclientproxy.net", 8080) ) );
p.addLast(sslCtx.newHandler(ch.alloc(), host, port));
}
p.addLast(
new HttpClientCodec(),
new HttpObjectAggregator(8192),
WebSocketClientCompressionHandler.INSTANCE,
handler);
}
});
Channel ch = b.connect(uri.getHost(), port).sync().channel();
handler.handshakeFuture().sync();
BufferedReader console = new BufferedReader(new InputStreamReader(System.in));
while (true) {
String msg = console.readLine(); //THIS IS NULL IN DATA CENTER LOGS
if (msg == null) {
break;
} else if ("bye".equals(msg.toLowerCase())) {
ch.writeAndFlush(new CloseWebSocketFrame());
ch.closeFuture().sync();
break;
} else if ("ping".equals(msg.toLowerCase())) {
WebSocketFrame frame = new PingWebSocketFrame(Unpooled.wrappedBuffer(new byte[] { 8, 1, 8, 1 }));
ch.writeAndFlush(frame);
} else {
WebSocketFrame frame = new TextWebSocketFrame(msg);
ch.writeAndFlush(frame);
}
}
} finally {
group.shutdownGracefully();
}
Handler:
public class WebSocketClientHandler extends SimpleChannelInboundHandler<Object> {
private final WebSocketClientHandshaker handshaker;
private ChannelPromise handshakeFuture;
public WebSocketClientHandler(WebSocketClientHandshaker handshaker) {
this.handshaker = handshaker;
}
public ChannelFuture handshakeFuture() {
return handshakeFuture;
}
#Override
public void handlerAdded(ChannelHandlerContext ctx) {
handshakeFuture = ctx.newPromise();
}
#Override
public void channelActive(ChannelHandlerContext ctx) {
handshaker.handshake(ctx.channel());
}
#Override
public void channelInactive(ChannelHandlerContext ctx) {
System.out.println("WebSocket Client disconnected!");
}
#Override
public void channelRead0(ChannelHandlerContext ctx, Object msg) throws Exception {
Channel ch = ctx.channel();
if (!handshaker.isHandshakeComplete()) {
try {
handshaker.finishHandshake(ch, (FullHttpResponse) msg);
System.out.println("WebSocket Client connected!");
handshakeFuture.setSuccess();
} catch (WebSocketHandshakeException e) {
System.out.println("WebSocket Client failed to connect");
handshakeFuture.setFailure(e);
}
return;
}
The application is able to connect to the websocket server endpoint from my local machine successfully.
But in the company datacenter where my application is deployed, I see the msg value is null and the websocket client is disconnected
Does that mean my connection is blocked at firewall? If that is the case then why did the statement "WebSocket Client connected!" is printed at all?
Thanks
The httpproxyhandler you used is correct
Just remove the BufferredReader code as mentioned below when deploying in linux, docker, etc:
Netty WebSocket Client Channel always gets inactive on Linux Server

I have the following Vertx Route setup:
router.post("/api/apple/")
.handler(e -> {
e.response()
.putHeader("content-type", "application/json")
.setStatusCode(200)
.end("hello");
})
.failureHandler(ctx -> {
LOG.error("Error: "+ ctx.response().getStatusMessage());
ctx.response().end();
});
vertx.createHttpServer().requestHandler(router::accept)
.listen(config().getInteger("http.port", 8081), result -> {
if (result.succeeded()) {
LOG.info("result succeeded in my start method");
future.complete();
} else {
LOG.error("result failed");
future.fail(result.cause());
}
});
When I call this from my Java test client:
Async async = context.async();
io.vertx.core.http.HttpClient client = vertx.createHttpClient();
HttpClientRequest request = client.post(8081, "localhost", "/api/apple/", response -> {
async.complete();
LOG.info("Some callback {}",response.statusCode());
});
String body = "{'username':'www','password':'www'}";
request.putHeader("content-length", "1000");
request.putHeader("content-type", "application/x-www-form-urlencoded");
request.write(body);
request.end();
The client keeps running and then the client times out. Seems like it is not able to find the endpoint on localhost:8081/api/apple
You didn't deploy your verticle defining routes in the test scope. Here is a working snippet:
public class HttpServerVerticleTest extends VertxTestRunner {
private WebClient webClient;
private HttpServerVerticle httpServer;
private int port;
#Before
public void setUp(TestContext context) throws IOException {
port = 8081;
httpServer = new HttpServerVerticle(); // the verticle where your routes are registered
// NOTICE HERE
vertx.deployVerticle(httpServer, yourdeploymentOptions, context.asyncAssertSuccess());
webClient = WebClient.wrap(vertx.createHttpClient());
}
#After
public void tearDown(TestContext testContext) {
webClient.close();
vertx.close(testContext.asyncAssertSuccess());
}
#Test
public void test_my_post_method(TestContext testContext) {
Async http = testContext.async();
String body = "{'username':'www','password':'www'}";
webClient.post(port, "localhost", "/api/apple/")
//.putHeader("Authorization", JWT_TOKEN)
.putHeader("content-length", "1000");
.putHeader("content-type", "application/x-www-form-urlencoded");
.sendJson(Buffer.buffer(body.getBytes()), requestResponse -> {
if (requestResponse.succeeded()) {
testContext.assertTrue(requestResponse.result().statusCode() == HttpResponseStatus.OK.code());
testContext.assertTrue(requestResponse.result().body().getString().equals("hello"));
} else {
testContext.fail(requestResponse.cause());
}
http.complete();
});
}
}
I have wasted several hours trying to solve a issue with the use of netty's channel pool map and a jax rs client.
I have used jersey's own netty connector as an inspiration but exchanged netty's channel with netty's channel pool map.
https://jersey.github.io/apidocs/2.27/jersey/org/glassfish/jersey/netty/connector/NettyConnectorProvider.html
My problem is that I have references that I need inside my custom SimpleChannelInboundHandler. However by the design of netty's way to create a channel pool map, I can not pass the references through my custom ChannelPoolHandler, because as soon as the pool map has created a pool the constructor of the channel pool handler never runs again.
This is the method where it makes acquires a pool and check out a channel to make a HTTP request.
#Override
public Future<?> apply(ClientRequest request, AsyncConnectorCallback callback) {
final CompletableFuture<Object> completableFuture = new CompletableFuture<>();
try{
HttpRequest httpRequest = buildHttpRequest(request);
// guard against prematurely closed channel
final GenericFutureListener<io.netty.util.concurrent.Future<? super Void>> closeListener =
future -> {
if (!completableFuture.isDone()) {
completableFuture.completeExceptionally(new IOException("Channel closed."));
}
};
try {
ClientRequestDTO clientRequestDTO = new ClientRequestDTO(NettyChannelPoolConnector.this, request, completableFuture, callback);
dtoMap.putIfAbsent(request.getUri(), clientRequestDTO);
// Retrieves a channel pool for the given host
FixedChannelPool pool = this.poolMap.get(clientRequestDTO);
// Acquire a new channel from the pool
io.netty.util.concurrent.Future<Channel> f = pool.acquire();
f.addListener((FutureListener<Channel>) futureWrite -> {
//Succeeded with acquiring a channel
if (futureWrite.isSuccess()) {
Channel channel = futureWrite.getNow();
channel.closeFuture().addListener(closeListener);
try {
if(request.hasEntity()) {
channel.writeAndFlush(httpRequest);
final JerseyChunkedInput jerseyChunkedInput = new JerseyChunkedInput(channel);
request.setStreamProvider(contentLength -> jerseyChunkedInput);
if(HttpUtil.isTransferEncodingChunked(httpRequest)) {
channel.write(jerseyChunkedInput);
} else {
channel.write(jerseyChunkedInput);
}
executorService.execute(() -> {
channel.closeFuture().removeListener(closeListener);
try {
request.writeEntity();
} catch (IOException ex) {
callback.failure(ex);
completableFuture.completeExceptionally(ex);
}
});
channel.flush();
} else {
channel.closeFuture().removeListener(closeListener);
channel.writeAndFlush(httpRequest);
}
} catch (Exception ex) {
System.err.println("Failed to sync and flush http request" + ex.getLocalizedMessage());
}
pool.release(channel);
}
});
} catch (NullPointerException ex) {
System.err.println("Failed to acquire socket from pool " + ex.getLocalizedMessage());
}
} catch (Exception ex) {
completableFuture.completeExceptionally(ex);
return completableFuture;
}
return completableFuture;
}
This is my ChannelPoolHandler
public class SimpleChannelPoolHandler implements ChannelPoolHandler {
private ClientRequestDTO clientRequestDTO;
private boolean ssl;
private URI uri;
private int port;
SimpleChannelPoolHandler(URI uri) {
this.uri = uri;
if(uri != null) {
this.port = uri.getPort() != -1 ? uri.getPort() : "https".equals(uri.getScheme()) ? 443 : 80;
ssl = "https".equalsIgnoreCase(uri.getScheme());
}
}
#Override
public void channelReleased(Channel ch) throws Exception {
System.out.println("Channel released: " + ch.toString());
}
#Override
public void channelAcquired(Channel ch) throws Exception {
System.out.println("Channel acquired: " + ch.toString());
}
#Override
public void channelCreated(Channel ch) throws Exception {
System.out.println("Channel created: " + ch.toString());
int readTimeout = Integer.parseInt(ApplicationEnvironment.getInstance().get("READ_TIMEOUT"));
SocketChannelConfig channelConfig = (SocketChannelConfig) ch.config();
channelConfig.setConnectTimeoutMillis(2000);
ChannelPipeline channelPipeline = ch.pipeline();
if(ssl) {
SslContext sslContext = SslContextBuilder.forClient().trustManager(InsecureTrustManagerFactory.INSTANCE).build();
channelPipeline.addLast("ssl", sslContext.newHandler(ch.alloc(), uri.getHost(), this.port));
}
channelPipeline.addLast("client codec", new HttpClientCodec());
channelPipeline.addLast("chunked content writer",new ChunkedWriteHandler());
channelPipeline.addLast("content decompressor", new HttpContentDecompressor());
channelPipeline.addLast("read timeout", new ReadTimeoutHandler(readTimeout, TimeUnit.MILLISECONDS));
channelPipeline.addLast("business logic", new JerseyNettyClientHandler(this.uri));
}
}
And this is my SimpleInboundHandler
public class JerseyNettyClientHandler extends SimpleChannelInboundHandler<HttpObject> {
private final NettyChannelPoolConnector nettyChannelPoolConnector;
private final LinkedBlockingDeque<InputStream> isList = new LinkedBlockingDeque<>();
private final AsyncConnectorCallback asyncConnectorCallback;
private final ClientRequest jerseyRequest;
private final CompletableFuture future;
public JerseyNettyClientHandler(ClientRequestDto clientRequestDTO) {
this.nettyChannelPoolConnector = clientRequestDTO.getNettyChannelPoolConnector();
ClientRequestDTO cdto = clientRequestDTO.getNettyChannelPoolConnector().getDtoMap().get(clientRequestDTO.getClientRequest());
this.asyncConnectorCallback = cdto.getCallback();
this.jerseyRequest = cdto.getClientRequest();
this.future = cdto.getFuture();
}
#Override
protected void channelRead0(ChannelHandlerContext ctx, HttpObject msg) throws Exception {

}, jerseyRequest);
for (Map.Entry<String, String> entry : httpResponse.headers().entries()) {
response.getHeaders().add(entry.getKey(), entry.getValue());
}
if((httpResponse.headers().contains(HttpHeaderNames.CONTENT_LENGTH) && HttpUtil.getContentLength(httpResponse) > 0) || HttpUtil.isTransferEncodingChunked(httpResponse)) {
ctx.channel().closeFuture().addListener(future -> isList.add(NettyInputStream.END_OF_INPUT_ERROR));
response.setEntityStream(new NettyInputStream(isList));
} else {
response.setEntityStream(new InputStream() {
#Override
public int read() {
return -1;
}
});
}
if(asyncConnectorCallback != null) {
nettyChannelPoolConnector.executorService.execute(() -> {
asyncConnectorCallback.response(response);
future.complete(response);
});
}
}
if(msg instanceof HttpContent) {
HttpContent content = (HttpContent) msg;
ByteBuf byteContent = content.content();
if(byteContent.isReadable()) {
byte[] bytes = new byte[byteContent.readableBytes()];
byteContent.getBytes(byteContent.readerIndex(), bytes);
isList.add(new ByteArrayInputStream(bytes));
}
}
if(msg instanceof LastHttpContent) {
isList.add(NettyInputStream.END_OF_INPUT);
}
}
#Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {

nettyChannelPoolConnector.executorService.execute(() -> asyncConnectorCallback.failure(cause));
}
future.completeExceptionally(cause);
isList.add(NettyInputStream.END_OF_INPUT_ERROR);
}
The references needed to be passed to the SimpleChannelInboundHandler is what is packed into the ClientRequestDTO as seen in the first code block.
I am not sure as it is not a tested code. But it could be achieved by the following code.
SimpleChannelPool sPool = poolMap.get(Req.getAddress());
Future<Channel> f = sPool.acquire();
f.get().pipeline().addLast("inbound", new NettyClientInBoundHandler(Req, jbContext, ReportData));
f.addListener(new NettyClientFutureListener(this.Req, sPool));
where Req, jbContext, ReportData could be input data for InboundHandler().
I want to build an API based on Futures (from java.util.concurrent) that is powered by a custom protocol on top of Netty (version 4). Basic idea is to write a simple library that would abstract the underlying Netty implementation and make it easier to make requests.
Using this library, one should be able to write something like this:
Request req = new Request(...);
Future<Response> responseFuture = new ServerIFace(host, port).call(req);
// For example, let's block until this future is resolved
Reponse res = responseFuture.get().getResult();
Underneath this code, a Netty client is connected
public class ServerIFace {
private Bootstrap bootstrap;
private EventLoopGroup workerGroup;
private String host;
private int port;
public ServerIFace(String host, int port) {
this.host = host;
this.port = port;
this.workerGroup = new NioEventLoopGroup();
bootstrap();
}
private void bootstrap() {
bootstrap = new Bootstrap();
bootstrap.group(workerGroup);
bootstrap.channel(NioSocketChannel.class);
bootstrap.handler(new ChannelInitializer<SocketChannel>() {
#Override
protected void initChannel(SocketChannel ch) throws Exception {
ch.pipeline().addLast(new ObjectEncoder());
ch.pipeline().addLast(new ObjectDecoder(ClassResolvers.cacheDisabled(Response.class.getClassLoader())));
ch.pipeline().addLast("response", new ResponseReceiverChannelHandler());
}
});
}
public Future<Response> call(final Request request) throws InterruptedException {
CompletableFuture<Response> responseFuture = new CompletableFuture<>();
Channel ch = bootstrap.connect(host, port).sync().channel();
ch.writeAndFlush(request).addListener((f) -> {
if (f.isSuccess()) {
System.out.println("Wrote successfully");
} else {
f.cause().printStackTrace();
}
});
ChannelFuture closeFuture = ch.closeFuture();
// Have to 'convert' ChannelFuture to java.util.concurrent.Future
closeFuture.addListener((f) -> {
if (f.isSuccess()) {
// How to get this response?
Response response = ((ResponseReceiverChannelHandler) ch.pipeline().get("response")).getResponse();
responseFuture.complete(response);
} else {
f.cause().printStackTrace();
responseFuture.cancel(true);
}
ch.close();
}).sync();
return responseFuture;
}
}
Now, as you can see, in order to abstract Netty's inner ChannelFuture, I have to 'convert' it to Java's Future (I'm aware that ChannelFuture is derived from Future, but that information doesn't seem useful at this point).
Right now, I'm capturing this Response object in the last handler of my inbound part of the client pipeline, the ResponseReceiverChannelHandler.
public class ResponseReceiverChannelHandler extends ChannelInboundHandlerAdapter {
private Response response = null;
#Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
this.response = (Response)msg;
ctx.close();
}
public Response getResponse() {
return response;
}
}
Since I'm new to Netty and these things in general, I'm looking for a cleaner, thread-safe way of delivering this object to the API user.
Correct me if I'm wrong, but none of the Netty examples show how to achieve this, and most of the Client examples just print out whatever they get from Server.
Please note that my main goal here is to learn more about Netty, and that this code has no production purposes.
For the reference (although I don't think it's that relevant) here's the Server code.
public class Server {
public static class RequestProcessorHandler extends ChannelInboundHandlerAdapter {
#Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
ChannelFuture future;
if (msg instanceof Request) {
Request req = (Request)msg;
Response res = some function of req
future = ctx.writeAndFlush(res);
} else {
future = ctx.writeAndFlush("Error, not a request!");
}
future.addListener((f) -> {
if (f.isSuccess()) {
System.out.println("Response sent!");
} else {
System.out.println("Response not sent!");
f.cause().printStackTrace();
}
});
}
}
public int port;
public Server(int port) {
this.port = port;
}
public void run() throws Exception {
EventLoopGroup bossGroup = new NioEventLoopGroup();
EventLoopGroup workerGroup = new NioEventLoopGroup();
try {
ServerBootstrap b = new ServerBootstrap();
b.group(bossGroup, workerGroup)
.channel(NioServerSocketChannel.class)
.childHandler(new ChannelInitializer<SocketChannel>() {
#Override
public void initChannel(SocketChannel ch) throws Exception {
ch.pipeline().addLast(new ObjectDecoder(ClassResolvers.cacheDisabled(Request.class.getClassLoader())));
ch.pipeline().addLast(new ObjectEncoder());
// Not really shutting down this threadpool but it's ok for now
ch.pipeline().addLast(new DefaultEventExecutorGroup(2), new RequestProcessorHandler());
}
})
.option(ChannelOption.SO_BACKLOG, 128)
.childOption(ChannelOption.SO_KEEPALIVE, true);
ChannelFuture f = b.bind(port).sync();
f.channel().closeFuture().sync();
} finally {
workerGroup.shutdownGracefully();
bossGroup.shutdownGracefully();
}
}
public static void main(String[] args) throws Exception {
int port;
if (args.length > 0) {
port = Integer.parseInt(args[0]);
} else {
port = 8080;
}
new Server(port).run();
}
}
I am new to spark streaming. I want to stream a url online in order to retrieve info from a certain URL, I used the JavaCustomReceiver in order to stream a url.
This is the code I'm using (source)
public class JavaCustomReceiver extends Receiver<String> {
private static final Pattern SPACE = Pattern.compile(" ");
public static void main(String[] args) throws Exception {
SparkConf sparkConf = new SparkConf().setAppName("JavaCustomReceiver");
JavaStreamingContext ssc = new JavaStreamingContext(sparkConf, new Duration(1000));
JavaReceiverInputDStream<String> lines = ssc.receiverStream(
new JavaCustomReceiver("http://stream.meetup.com/2/rsvps", 80));
JavaDStream<String> words = lines.flatMap(new
FlatMapFunction<String, String>() {
#Override
public Iterator<String> call(String x) {
return Arrays.asList(SPACE.split(x)).iterator();
}
});
JavaPairDStream<String, Integer> wordCounts = words.mapToPair(
new PairFunction<String, String, Integer>() {
#Override
public Tuple2<String, Integer> call(String s) {
return new Tuple2<>(s, 1);
}
}).reduceByKey(new Function2<Integer, Integer, Integer>() {
#Override
public Integer call(Integer i1, Integer i2) {
return i1 + i2;
}
});
wordCounts.print();
ssc.start();
ssc.awaitTermination();
}
String host = null;
int port = -1;
public JavaCustomReceiver(String host_, int port_) {
super(StorageLevel.MEMORY_AND_DISK_2());
host = host_;
port = port_;
}
public void onStart() {
new Thread() {
#Override
public void run() {
receive();
}
}.start();
}
public void onStop() {
}
private void receive() {
try {
Socket socket = null;
BufferedReader reader = null;
String userInput = null;
try {
// connect to the server
socket = new Socket(host, port);
reader = new BufferedReader(
new InputStreamReader(socket.getInputStream(), StandardCharsets.UTF_8));
// Until stopped or connection broken continue reading
while (!isStopped() && (userInput = reader.readLine()) != null) {
System.out.println("Received data '" + userInput + "'");
store(userInput);
}
} finally {
Closeables.close(reader, /* swallowIOException = */ true);
Closeables.close(socket, /* swallowIOException = */ true);
}
restart("Trying to connect again");
} catch (ConnectException ce) {
// restart if could not connect to server
restart("Could not connect", ce);
} catch (Throwable t) {
restart("Error receiving data", t);
}
}
}
However, I keep getting a java.net.UnknownHostException
How can I fix this? What is wrong with the code that I'm using ?
After reading the code of the custom receiver referenced, it is clear that it is a TCP receiver that connects to a host:port and not an HTTP receiver that could take an URL. You'll have to change the code to read from an HTTP endpoint.
I'm trying to do a client SNI app, for a integration test I'm using a Grizzly server to test the SNI is being passed. I'm using a Filter as per docs. However the filter is never called.
The documentation doesn't show a complete example. The mechanism I've found to add filters seems to be ignored. The old method used in 2.2 is not public anymore.
The following is my code:
private TCPNIOTransport createMockServerTransport() {
final SSLEngineConfigurator sslServerEngineConfig = new SSLEngineConfigurator(createSSLContextConfigurator().createSSLContext(), false, false, false);
return TCPNIOTransportBuilder.newInstance().setProcessor(getFilters()).build();
}
private FilterChain getFilters() {
SNIFilter sniFilter = getSniFilter();
final FilterChain chain = FilterChainBuilder.stateless()
.add(new TransportFilter())
.add(sniFilter)
.add(new StringFilter())
.add(new BaseFilter() {
#Override
public NextAction handleRead(final FilterChainContext ctx)
throws IOException {
return ctx.getInvokeAction();
}
})
.build();
return chain;
}
private SNIFilter getSniFilter() {
final Attribute<String> sniHostAttr = Grizzly.DEFAULT_ATTRIBUTE_BUILDER.createAttribute("sni-host-attr");
SNIFilter sniFilter = new SNIFilter();
sniFilter.setServerSSLConfigResolver(new SNIServerConfigResolver() {
#Override
public SNIConfig resolve(Connection connection, String hostname) {
sniHostAttr.set(connection, hostname);
if (StringUtils.isEmpty(hostname)) {
throw new IllegalArgumentException("SNI Has not been sent");
}
return SNIConfig.newServerConfig(sslServerEngineConfig);
}
});
return sniFilter;
}
private SSLContextConfigurator createSSLContextConfigurator() {
SSLContextConfigurator sslContextConfigurator = new SSLContextConfigurator();
ClassLoader cl = HttpRequestSNITestCase.class.getClassLoader();
URL cacertsUrl = cl.getResource("trustStore");
if (cacertsUrl != null) {
sslContextConfigurator.setTrustStoreFile(cacertsUrl.getFile());
sslContextConfigurator.setTrustStorePass("myPassword");
}
URL keystoreUrl = cl.getResource("serverKeystore");
if (cacertsUrl != null) {
sslContextConfigurator.setKeyStoreFile(keystoreUrl.getFile());
sslContextConfigurator.setKeyStorePass("myPassword");
sslContextConfigurator.setKeyPass("myPassword");
}
return sslContextConfigurator;
}
public class Server {
private HttpServer webServer;
protected void startServer() throws IOException {
SSLEngineConfigurator sslServerEngineConfig = new SSLEngineConfigurator(createSSLContextConfigurator().createSSLContext(), false, false, false);
NetworkListener networkListener = new NetworkListener("sample-listener", "localhost", httpsPort.getNumber());
networkListener.setTransport(createMockServerTransport());
networkListener.setSSLEngineConfig(sslServerEngineConfig);

networkListener.getTransport().setProcessor(getFilters());
FilterChain chain = networkListener.getFilterChain();
webServer.start();
}

}
In order to update the HttpServer filter chain you have to use AddOn:
protected void startServer() throws IOException {
NetworkListener networkListener = new NetworkListener("sample-listener", "localhost", 8081);
sslServerEngineConfig = new SSLEngineConfigurator(createSSLContextConfigurator().createSSLContext(), false, false, false);
networkListener.setSSLEngineConfig(sslServerEngineConfig);
networkListener.setSecure(true);
networkListener.registerAddOn(new SniAddOn());
webServer = HttpServer.createSimpleServer();
webServer.addListener(networkListener);
webServer.start();
}
private class SniAddOn implements AddOn {
public void setup(NetworkListener networkListener,
FilterChainBuilder builder) {
// replace SSLFilter (if any) with SNIFilter
final int idx = builder.indexOfType(SSLBaseFilter.class);
if (idx != -1) {
builder.set(idx, getSniFilter());
}
}
}
