Annotation Type InjectChannel

  • @Autowired
@Qualifier
@Documented
@Retention(RUNTIME)
@Target({METHOD,FIELD,PARAMETER,ANNOTATION_TYPE})
public @interface InjectChannel
    Provides support for MessagingChannels autowiring.

    This annotation can be placed on any autowire-capable elements (fields, properties, parameters, etc) of application beans in order to inject MessagingChannel by its name.

    Below is the example of how this annotation can be used.

    1) Define a bean that will use InjectChannel annotation to inject MessagingChannel into its field. 

    
@Component
public class MyBean {
    @InjectChannel("my-channel")
    private MessagingChannel<Object> channel;

    // ... other fields and methods...
}
    2) Define a Spring Boot application that will provide channel configuration. 
    
@EnableHekate
@SpringBootApplication
public class MyApp {
    @Bean
    public MessagingChannelConfig<Object> messagingChannelConfig() {
        return MessagingChannelConfig.unchecked()
            .withName("my-channel")
            .withReceiver(msg ->
                System.out.println("Got message " + msg)
            );
    }

    // ... other beans and methods...
}
