Spring Boot ActiveMQ websocket STOMP connection with SpringMessaging 5.x.x - spring

Question

I have problem updating spring messaging form 4.x.x to 5.x.x. In newer version Reactor2TcpClient is replaced with ReactorNettyTcpClient which is giving me a hard time.
This is my working code using old spring messaging:
package com.example.websockets;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.broker.AbstractBrokerMessageHandler;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.messaging.simp.stomp.StompBrokerRelayMessageHandler;
import org.springframework.messaging.tcp.reactor.Reactor2TcpClient;
import org.springframework.web.socket.config.annotation.DelegatingWebSocketMessageBrokerConfiguration;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
#Configuration
class MyStompBrokerRelayMessageHandler extends DelegatingWebSocketMessageBrokerConfiguration {
#Bean
public AbstractBrokerMessageHandler stompBrokerRelayMessageHandler() {
StompBrokerRelayMessageHandler handler = (StompBrokerRelayMessageHandler) super.stompBrokerRelayMessageHandler();
handler.setTcpClient(new Reactor2TcpClient<>(
new StompTcpFactory(
"stompLink",
stompPort,
true)
));
return handler;
}
#Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableStompBrokerRelay("/queue", "/topic")
.setRelayHost("wssLink")
.setRelayPort(wssPort)
.setSystemLogin("adminLogin")
.setSystemPasscode("adminPassword")
.setClientLogin("clientLogin")
.setClientPasscode("clientPassword");
config.setApplicationDestinationPrefixes("/app");
}
#Override
protected void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/gs-guide-websocket").withSockJS();
}
}
and
package com.example.websockets;
import io.netty.channel.EventLoopGroup;
import org.springframework.messaging.Message;
import org.springframework.messaging.simp.stomp.Reactor2StompCodec;
import org.springframework.messaging.simp.stomp.StompDecoder;
import org.springframework.messaging.simp.stomp.StompEncoder;
import org.springframework.messaging.tcp.reactor.Reactor2TcpClient;
import reactor.Environment;
import reactor.core.config.ReactorConfiguration;
import reactor.io.net.NetStreams;
import reactor.io.net.Spec;
import reactor.io.net.config.SslOptions;
import reactor.io.net.impl.netty.NettyClientSocketOptions;
import java.util.Properties;
import static java.util.Collections.emptyList;
public class StompTcpFactory implements NetStreams.TcpClientFactory<Message<byte[]>, Message<byte[]>> {
private final Environment environment;
private final EventLoopGroup eventLoopGroup;
private final String host;
private final int port;
private final boolean ssl;
StompTcpFactory(String host, int port, boolean ssl) {
this.host = host;
this.port = port;
this.ssl = ssl;
this.environment = new Environment(() -> new ReactorConfiguration(emptyList(), "sync", new Properties()));
this.eventLoopGroup = Reactor2TcpClient.initEventLoopGroup();
}
#Override
public Spec.TcpClientSpec<Message<byte[]>, Message<byte[]>> apply(Spec.TcpClientSpec<Message<byte[]>, Message<byte[]>> tcpClientSpec) {
return tcpClientSpec
.env(environment)
.options(new NettyClientSocketOptions().eventLoopGroup(eventLoopGroup))
.codec(new Reactor2StompCodec(new StompEncoder(), new StompDecoder()))
.ssl(ssl ? new SslOptions() : null)
.connect(host, port);
}
}
and here are my dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-messaging</artifactId>
<version>4.3.13.RELEASE</version>
</dependency>
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>2.0.8.RELEASE</version>
</dependency>
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-net</artifactId>
<version>2.0.8.RELEASE</version>
</dependency>
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.1.28.Final</version>
</dependency>
In my failed attempt to update dependencies I was using this:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-messaging</artifactId>
<version>5.0.8.RELEASE</version>
</dependency>
<dependency>
<groupId>io.projectreactor.ipc</groupId>
<artifactId>reactor-netty</artifactId>
<version>0.7.8.RELEASE</version>
</dependency>
and I replaced:
#Bean
public AbstractBrokerMessageHandler stompBrokerRelayMessageHandler() {
StompBrokerRelayMessageHandler handler = (StompBrokerRelayMessageHandler) super.stompBrokerRelayMessageHandler();
handler.setTcpClient(new Reactor2TcpClient<>(
new StompTcpFactory(
"stompLink",
stompPort,
true)
));
return handler;
}
with:
#Bean
public AbstractBrokerMessageHandler stompBrokerRelayMessageHandler() {
StompBrokerRelayMessageHandler handler = (StompBrokerRelayMessageHandler) super.stompBrokerRelayMessageHandler();
handler.setTcpClient(new ReactorNettyTcpClient<>(
"stompLing",
stompPort,
new StompReactorNettyCodec(new StompDecoder(), new StompEncoder())));
return handler;
}
Any advice would be much appreciated.
