春MQTT集成

我想实现Spring集成而我运行应用程序，我可以接收订阅主题的消息，但如何能在运行时添加更多的主题春MQTT集成

我试图从控制器

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

和下面是我的豆子设置用于订阅主题

@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()); 

     } 

    }; 
} 
}

，我收到以下错误

这与MQTT无关，您的MqttInboundBeans对您没有声明的UserService类型的bean具有@Autowired依赖性。

编辑

新增例如：

@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; 
    } 

}

是，我需要它来保存从消息处理程序的消息，有什么建议？ – Rawat

'没有符合条件的'com.ehydromet.service.UserService'类型的可用bean意味着它的含义 - 您在任何地方都没有'UserService'' @ Bean'您对此应用程序上下文的配置。 –
