I try to autowire some service class in channelInboundhandler class field.
but when handler use repository field it always null.
Here is my Netty Configuration
my.netty:
server:
bind: 9000
#SpringBootApplication
public class NettyApplication {
public static void main(String[] args) {
SpringApplication.run(NettyApplication.class, args);
}
#Bean
NettyServerConfig serverConfig(#Autowired ServerHandler serverHandler) {
return NettyServerConfig.builder()
.propertiesPrefix("my.netty.server")
.channelInitializer(pipelineOf(loggingChannelHandler(), serverHandler))
.build();
}
#Bean
ChannelHandler loggingChannelHandler() {
return new LoggingHandler(INFO);
}
}
And channelinboundhandler, Service(Repository)
#Slf4j
#Component
#Sharable
public class ServerHandler extends ChannelInboundHandlerAdapter {
#Autowired ServerRepository repository; // always null
#Override
public void channelRead(ChannelHandlerContext ctx, Object object) throws Exception {
log.info("ServerHandler.channelRead()");
String data = repository.findOne();
log.info("data={}", data);
ctx.writeAndFlush(object);
}
}
#Repository
public class ServerRepository {
public String findOne() {
sleep(1000); // data-access time
return "data";
}
private void sleep(int millis) {
try {
Thread.sleep(millis);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
Is There any Problem?

I need to use autowired in more than one class with ScheduledExecutorService, what I have tried is shown in this code. logging size of User list in below example always shows 0, even after user added to arraylist. How to properly use Autowired and ScheduledExecutorService in spring boot?
#Component
public class AnotherClass {
List<User> users = new ArrayList();
public void addUser(User user){
users.add(user);
}
public void logUsers(){
logger.info("User size " + users.size()); <================= Always logs 0, when called from executor
}
}
#RestController
public class SecondClass {
#Autowired
private AnotherClass anotherClass;
#GetMapping(value="/user/test")
public void logUsers(){
anotherClass.addUser(new User());
}
}
Application Class
#Component
#SpringBootApplication
public class SpringBootDemoApplication {
private ScheduledExecutorService exec = Executors.newScheduledThreadPool(1);
#Autowired
private AnotherClass anotherClass;
#PostConstruct
public void init() {
logger();
}
public static void main(String[] args) {
SpringApplication.run(SpringBootDemoApplication.class, args);
}
public void logger(){
exec.scheduleAtFixedRate(new Runnable(){
#Override
public void run(){
try {
anotherClass.logUsers();
}catch (Exception e){
}
}
}, 2000, 1000, TimeUnit.MILLISECONDS);
}
}
The code works if you use the Spring #Autowired and not the #AutoWired Annotation.
I am trying to write and test an application that used spring-cloud with azure functions following this tutorial.
https://github.com/markusgulden/aws-tutorials/tree/master/spring-cloud-function/spring-cloud-function-azure/src/main/java/de/margul/awstutorials/springcloudfunction/azure
I am tryign to write a testcase and override the bean.
Here is the application class having function and handler Bean function.
#SpringBootApplication
#ComponentScan(basePackages = { "com.package" })
public class DataFunctions extends AzureSpringBootRequestHandler<GenericMessage<Optional<String>>, Data> {
#FunctionName("addData")
public HttpResponseMessage addDataRun(
#HttpTrigger(name = "add", methods = {
HttpMethod.POST }, authLevel = AuthorizationLevel.FUNCTION) HttpRequestMessage<Optional<String>> request,
final ExecutionContext context) throws JsonParseException, JsonMappingException, IOException {
context.getLogger().info("Java HTTP trigger processed a POST request.");
try {
handleRequest(new GenericMessage<Optional<String>>(request.getBody()), context);
} catch (ServiceException ex) {
ErrorMessage em = new ErrorMessage();
return request.createResponseBuilder(handleException(ex, em)).body(em).build();
}
return request.createResponseBuilder(HttpStatus.CREATED).build();
}
#Autowired
MyService mService;
#Bean
public Consumer<GenericMessage<Optional<String>>> addData() {
ObjectMapper mapper = new ObjectMapper();
return req -> {
SomeModel fp = null;
try {
fp = mapper.readValue(req.getPayload().get(), SomeModel.class);
} catch (Exception e) {
throw new ServiceException(e);
}
mService.addData(fp);
};
}
}
I want to test by overriding the above bean.
Cosmosdb spring configuration
#Configuration
#EnableDocumentDbRepositories
public class CosmosDBConfig extends AbstractDocumentDbConfiguration {
#Value("${cosmosdb.collection.endpoint}")
private String uri;
#Value("${cosmosdb.collection.key}")
private String key;
#Value("${cosmosdb.collection.dbname}")
private String dbName;
#Value("${cosmosdb.connect.directly}")
private Boolean connectDirectly;
#Override
public DocumentDBConfig getConfig() {
ConnectionPolicy cp = ConnectionPolicy.GetDefault();
if (connectDirectly) {
cp.setConnectionMode(ConnectionMode.DirectHttps);
} else {
cp.setConnectionMode(ConnectionMode.Gateway);
}
return DocumentDBConfig.builder(uri, key, dbName).connectionPolicy(cp).build();
}
}
Here is the configuration
#TestConfiguration
#PropertySource(value = "classpath:application.properties", encoding = "UTF-8")
#Profile("test")
#Import({DataFunctions.class})
public class TestConfig {
#Bean(name="addData")
#Primary
public Consumer<GenericMessage<Optional<String>>> addData() {
return req -> {
System.out.println("data mock");
};
}
#Bean
#Primary
public DocumentDBConfig getConfig() {
return Mockito.mock(DocumentDBConfig.class);
}
}
Finally the test class
#RunWith(SpringRunner.class)
//#SpringBootTest //Enabling this gives initialization error.
#ActiveProfiles("test")
public class TempTest {
#InjectMocks
DataFunctions func;
#Mock
MyService mService;
#Before
public void setup() {
MockitoAnnotations.initMocks(this);
}
private Optional<String> createRequestString(final String res) throws IOException {
InputStream iStream = TempTest.class.getResourceAsStream(res);
String charset="UTF-8";
try (BufferedReader br = new BufferedReader(new InputStreamReader(iStream, charset))) {
return Optional.of(br.lines().collect(Collectors.joining(System.lineSeparator())));
}
}
#Test
public void testHttpPostTriggerJava() throws Exception {
#SuppressWarnings("unchecked")
final HttpRequestMessage<Optional<String>> req = mock(HttpRequestMessage.class);
final Optional<String> queryBody = createRequestString("/test-data.json");
doNothing().when(mService).addData(Mockito.any(SomeModel.class));
doReturn(queryBody).when(req).getBody();
doAnswer(new Answer<HttpResponseMessage.Builder>() {
#Override
public HttpResponseMessage.Builder answer(InvocationOnMock invocation) {
HttpStatus status = (HttpStatus) invocation.getArguments()[0];
return new HttpResponseMessageMock.HttpResponseMessageBuilderMock().status(status);
}
}).when(req).createResponseBuilder(any(HttpStatus.class));
final ExecutionContext context = mock(ExecutionContext.class);
doReturn(Logger.getGlobal()).when(context).getLogger();
doReturn("addData").when(context).getFunctionName();
// Invoke
final HttpResponseMessage ret = func.addDataRun(req, context);
// Verify
assertEquals(ret.getStatus(), HttpStatus.CREATED);
}
}
For this case instead of test configuration addData the actual bean is called from DataFunctions class. Also the database connection is also created when it should use the mocked bean from my test configuration. Can somebody please point out what is wrong in my test configuration?
I was able to resolve the first part of cosmos db config loading by marking it with
#Configuration
#EnableDocumentDbRepositories
#Profile("!test")
public class CosmosDBConfig extends AbstractDocumentDbConfiguration {
...
}
Also had to mark the repository bean as optional in the service.
public class MyService {
#Autowired(required = false)
private MyRepository myRepo;
}
Didn't use any spring boot configuration other than this.
#ActiveProfiles("test")
public class FunctionTest {
...
}
For the second part of providing mock version of Mock handlers, I simply made the test config file as spring application as below.
#SpringBootApplication
#ComponentScan(basePackages = { "com.boeing.da.helix.utm.traffic" })
#Profile("test")
public class TestConfiguration {
public static void main(final String[] args) {
SpringApplication.run(TestConfiguration.class, args);
}
#Bean(name="addData")
#Primary
public Consumer<GenericMessage<Optional<String>>> addData() {
return req -> {
System.out.println("data mock");
};
}
}
and made use of this constructor from azure functions library in spring cloud in my constructor
public class AppFunctions
extends AzureSpringBootRequestHandler<GenericMessage<Optional<String>>, List<Data>> {
public AppFunctions(Class<?> configurationClass) {
super(configurationClass);
}
}
public AzureSpringBootRequestHandler(Class<?> configurationClass) {
super(configurationClass);
}
Hope it helps someone.
I'm trying to use AOP with annotation triggering as you can see in this pointcut
package mypackage.aop;
// ...
#Aspect
#Component
public class ErrorHandlerAspect {
private final static Logger LOGGER = LoggerFactory.getLogger(ErrorHandlerAspect.class);
#Pointcut("within(mypackage.config.steps..*) && #annotation(mypackage.aop.SaveAndErrors)")
private void pointcut(){ }
#Around("pointcut()")
private Object errorHandler(ProceedingJoinPoint pjp) throws Throwable{
try{
return pjp.proceed();
} catch (Throwable e){
LOGGER.error("Handling error");
throw e;
}
}
}
Here are declaration of annotation :
package mypackage.aop;
// ...
#Target(ElementType.METHOD)
#Retention(RetentionPolicy.RUNTIME)
public #interface SaveAndErrors { }
... and usage in #Configuration class (for spring batch step configuration) :
package mypackage.config.steps;
// ...
#Configuration
public class StepConfiguration {
public final static String STEP_NAME = "xStep";
// ...
#SaveAndErrors
#Bean(name="xFileReader")
#StepScope
public ItemStreamReader<Object> xFileReader(#Value("#{stepExecutionContext['fileName']}") String resourceName // Inside a partitionner) throws xException {
try {
// ...
// return ...
} catch (yException e) {
throw new xException("new Exception :", e);
}
}
// ...
}
And my Application class :
#SpringBootApplication
public class Application { //...
}
Unfortunately, this is not working.
Removing && #annotation(mypackage.aop.SaveAndErrors) from pointcut, my aop proxy is working.
Where is the mistake?
I'm having a hard time to work with jersey test framework.
I have a root resource.
#Path("sample")
public class SampleResource {
#GET
#Path("path")
#Produces({MediaType.TEXT_PLAIN})
public String readPath() {
return String.valueOf(path);
}
#Inject
private java.nio.file.Path path;
}
I prepared a factory providing the path.
public class SamplePathFactory implements Factory<Path> {
#Override
public Path provide() {
try {
return Files.createTempDirectory(null);
} catch (final IOException ioe) {
throw new RuntimeException(ioe);
}
}
#Override
public void dispose(final Path instance) {
try {
Files.delete(instance);
} catch (final IOException ioe) {
throw new RuntimeException(ioe);
}
}
}
And a binder.
public class SamplePathBinder extends AbstractBinder {
#Override
protected void configure() {
bindFactory(SamplePathFactory.class).to(Path.class);
}
}
And, finally, my test class.
public class SampleResourceTest extends ContainerPerClassTest {
#Override
protected Application configure() {
final ResourceConfig resourceConfig
= new ResourceConfig(SampleResource.class);
resourceConfig.register(SamplePathBinder.class);
return resourceConfig;
}
}
When I tried to test, I got.
org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=Path,parent=SampleResource,qualifiers={},position=-1,optional=false,self=false,unqualified=null,1916953383)
What did I do wrong?
Your AbstractBinders should be registered as an instance, not as a class. So make the change
resourceConfig.register(new SamplePathBinder());
and it should work
Well, I have an abstract class like this:
public abstract class BasicCrudMBImpl<Bean, BO> extends BasicMBImpl {
protected Bean bean;
protected List<Bean> beans;
protected BO boPadrao;
public void deletar() {
try {
((BasicBO) boPadrao).delete((AbstractBean) bean);
addInfoMessage("Registro deletado com sucesso");
beans = retornaBeansDoBanco();
bean = null;
} catch (BOException e) {
addErrorMessage(e.getMessage());
}
}
public void salvar(ActionEvent event) {
try {
if (((AbstractBean) bean).getId() == null) {
bean = (Bean) ((BasicBO) boPadrao).save((AbstractBean) bean);
addInfoMessage("Registro salvo com sucesso");
} else {
((BasicBO) boPadrao).update((AbstractBean) bean);
addInfoMessage("Registro atualizado com sucesso");
}
beans = retornaBeansDoBanco();
} catch (BOException e) {
FacesContext.getCurrentInstance().validationFailed();
addErrorMessage(e.getMessage());
}
}
public Bean getBean() {
return bean;
}
public void setBean(Bean bean) {
this.bean = bean;
}
public List<Bean> getBeans() {
try {
if (beans == null)
beans = (List<Bean>) retornaBeansDoBanco();
return beans;
} catch (BOException e) {
addErrorMessage(e.getMessage());
}
return null;
}
public void setBeans(List<Bean> beans) {
this.beans = beans;
}
// Deve ser implementado para carregar a query adequada ao bean necessário
public abstract List<Bean> retornaBeansDoBanco();
public abstract void novo(ActionEvent event);
public abstract void alterar(ActionEvent event);
public BO getBoPadrao() {
return boPadrao;
}
public abstract void setBoPadrao(BO boPadrao);
public void addErrorMessage(String componentId, String errorMessage) {
addMessage(componentId, errorMessage, FacesMessage.SEVERITY_ERROR);
}
public void addErrorMessage(String errorMessage) {
addErrorMessage(null, errorMessage);
}
public void addInfoMessage(String componentId, String infoMessage) {
addMessage(componentId, infoMessage, FacesMessage.SEVERITY_INFO);
}
public void addInfoMessage(String infoMessage) {
addInfoMessage(null, infoMessage);
}
private void addMessage(String componentId, String errorMessage,
FacesMessage.Severity severity) {
FacesMessage message = new FacesMessage(errorMessage);
message.setSeverity(severity);
FacesContext.getCurrentInstance().addMessage(componentId, message);
}
}
In ManagedBean I tried to inject the "boPadrao" with #Autowired, like this:
#ManagedBean(name = "enderecoMB")
#ViewScoped
public class EnderecoMBImpl extends BasicCrudMBImpl<Endereco, BasicBO> {
private static Logger logger = Logger.getLogger(EnderecoMBImpl.class);
private List<TipoEndereco> tiposEndereco;
private List<Logradouro> logradouros;
#PostConstruct
public void init() {
logger.debug("Inicializando componentes no PostConstruct");
beans = retornaBeansDoBanco();
tiposEndereco = (List<TipoEndereco>) boPadrao
.findByNamedQuery(TipoEndereco.FIND_ALL);
logradouros = (List<Logradouro>) boPadrao
.findByNamedQuery(Logradouro.FIND_ALL_COMPLETO);
}
#Override
public List<Endereco> retornaBeansDoBanco() {
return (List<Endereco>) getBoPadrao().findByNamedQuery(Endereco.FIND_ALL_COMPLETO);
}
#Override
public void novo(ActionEvent event) {
bean = new Endereco();
}
#Override
public void alterar(ActionEvent event) {
// TODO Auto-generated method stub
}
public List<TipoEndereco> getTiposEndereco() {
return tiposEndereco;
}
public void setTiposEndereco(List<TipoEndereco> tiposEndereco) {
this.tiposEndereco = tiposEndereco;
}
public List<Logradouro> getLogradouros() {
return logradouros;
}
public void setLogradouros(List<Logradouro> logradouros) {
this.logradouros = logradouros;
}
#Autowired
public void setBoPadrao(BasicBO boPadrao) {
this.boPadrao = boPadrao;
}
}
But this doesn't works, the boPadrao is always null, getting a "NullPointerException". The error occurs in method retornaBeansDoBanco();
