Not able to stop a JMS consumer in Spring Boot with JmsListenerEndpointRegistry-CodePudding

MqStartStopDemoApplication.java

@SpringBootApplication
public class MqStartStopDemoApplication implements CommandLineRunner {

    @Autowired
    private Queue queue;
    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        SpringApplication.run(MqStartStopDemoApplication.class, args);
    }

    @Override
    public void run(String... args) throws InterruptedException {
        while (true) {
            jmsTemplate.convertAndSend(queue, "Hello");
            Thread.currentThread().sleep(1000);
        }
    }

}

JMSConfig.java

@Configuration
@EnableJms
public class JMSConfig {

    @Bean
    public Queue queue() {
        return new ActiveMQQueue("simple-jms-queue");
    }

}

Consumer.java

@Component
public class Consumer {

    @JmsListener(destination = "simple-jms-queue")
    public void listener(String msg) {
        System.out.println("Received Message : "   msg);
    }
}

JmsController.java

@RestController
@RequestMapping("/jms")
public class JmsController {

    @Autowired
    ApplicationContext context;

    @RequestMapping(value = "/halt", method = RequestMethod.GET)
    public @ResponseBody
    String haltJmsListener() {
        JmsListenerEndpointRegistry customRegistry = context.getBean("consumer", JmsListenerEndpointRegistry.class);
        customRegistry.stop();
        return "Jms Listener Stopped";
    }
 ...

}

When I run the application and then hit http://localhost:8080/jms/halt

CodePudding user response：

What makes you think the registry is a bean named consumer?

The registry has a reference to each listener container created for each JmsListener.

Just use

JmsListenerEndpointRegistry customRegistry = context.getBean(JmsListenerEndpointRegistry.class);

instead.

The actual bean name is JmsListenerConfigUtils.JMS_LISTENER_ENDPOINT_REGISTRY_BEAN_NAME ("org.springframework.jms.config.internalJmsListenerEndpointRegistry").
