私は春の統合を実装しようとしていますし、私はアプリケーションを実行している間、私は加入のトピックにメッセージを受け取ることができますが、実行時に複数のトピックを追加することができますどのように私は、コントローラ春MQTT統合

から、次の機能を試してみました 

@RequestMapping("/suscribetest") 
    @ResponseBody 
public String subscribeTest(){ 
    AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(MqttInboundBeans.class); 
    MqttPahoMessageDrivenChannelAdapter messageChannel = context.getBean("inbound",MqttPahoMessageDrivenChannelAdapter.class); 
    messageChannel.addTopic("test", 2); 
    return ""; 
}

と話題 

@Configuration 
public class MqttInboundBeans { 
    @Autowired 
private UserService service; 


@Bean 
public MessageChannel mqttInputChannel() { 
    return new DirectChannel(); 
} 

@Bean 
public MessageProducer inbound() { 
    MqttPahoMessageDrivenChannelAdapter adapter = 
      new MqttPahoMessageDrivenChannelAdapter("tcp://localhost:1883", "testClient", 
              "DATA/#", "LD/#"); 
    adapter.setCompletionTimeout(0); 
    adapter.setConverter(new DefaultPahoMessageConverter()); 
    adapter.setQos(2); 
    adapter.setOutputChannel(mqttInputChannel()); 
    return adapter; 
} 

@Bean 
@ServiceActivator(inputChannel = "mqttInputChannel") 
public MessageHandler handler() { 
    return new MessageHandler() { 

     @Override 
     public void handleMessage(Message<?> message) throws MessagingException { 
      System.out.println(message.getHeaders()+" "+message.getPayload()); 

     } 

    }; 
} 
}

を購読し、私は次のエラー

MQTTとはまったく関係がありません。MqttInboundBeansには、UserServiceのBeanには@Autowiredの依存関係があります。これには宣言がありません。

EDIT

追加例：

@SpringBootApplication 
@Controller 
public class So42578862Application { 

    public static void main(String[] args) { 
     SpringApplication.run(So42578862Application.class, args); 
    } 

    @Autowired 
    private MqttPahoMessageDrivenChannelAdapter adapter; 

    @RequestMapping("/subscribeTest") 
    @ResponseBody 
    public String handle() { 
     if (adapter.getTopic().length == 0) { 
      adapter.addTopic("DATA/#", "LD/#"); 
     } 
     return ""; 
    } 

    @Bean 
    public MqttPahoMessageDrivenChannelAdapter inbound() { 
     MqttPahoMessageDrivenChannelAdapter adapter = new MqttPahoMessageDrivenChannelAdapter("tcp://localhost:1883", 
       "testClient", new String[0]); 
     adapter.setCompletionTimeout(0); 
     adapter.setConverter(new DefaultPahoMessageConverter()); 
     adapter.setQos(2); 
     adapter.setOutputChannelName("mqttInputChannel"); 
     return adapter; 
    } 

    @Bean 
    @ServiceActivator(inputChannel = "mqttInputChannel") 
    public MessageHandler handler() { 
     return new MessageHandler() { 

      @Override 
      public void handleMessage(Message<?> message) throws MessagingException { 
       System.out.println(message.getHeaders() + " " + message.getPayload()); 

      } 

     }; 
    } 

    @InboundChannelAdapter(channel = "out", poller = @Poller(fixedDelay = "5000")) 
    public String message() { 
     return "foo"; 
    } 

    @Bean 
    @ServiceActivator(inputChannel = "out") 
    public MqttPahoMessageHandler outHandler() { 
     MqttPahoMessageHandler outHandler = new MqttPahoMessageHandler("tcp://localhost:1883", "outClient"); 
     outHandler.setDefaultTopic("DATA/foo"); 
     return outHandler; 
    } 

}

はい、私はそれがメッセージハンドラからのメッセージを保存する必要があり、任意の提案ですか？ – Rawat

'タイプの修飾Beanはありません 'com.ehydromet.service.UserService' available 'は、それが何を言っているかを正確に意味しています - あなたは' UserService' '@ Bean'をどこにも持っていませんこのアプリケーションコンテキストの構成。 –
