如何接收消息从IBMMQ JMS使用Spring引导连续？

Question

我有一个Spring Boot应用程序，它接收JSON请求并将其推送到IBM MQ JMS队列中。可能有n个JSON请求将被推送到队列。我的目标是处理队列中的每个请求。如何侦听队列并使用spring boot逐个处理消息？

Answer 1

您需要实现监听器为：

1：创建并配置以下内容：

@Bean
public MQConnectionFactory mqConnectionFactory(){
  MQConnectionFactory connectionFactory = new MQConnectionFactory();
  connectionFactory.setHostName(); //mq host name
  connectionFactory.setPort(); // mq port
  connectionFactory.setQueueManager(); //mq queue manager
  connectionFactory.setChannel(); //mq channel name
  connectionFactory.setTransportType(1);
  connectionFactory.setSSLCipherSuite(); //tls cipher suite name
  return connectionFactory;
}


@Bean()
public DefaultMessageListenerContainer myMessageEventContainer() {
  DefaultMessageListenerContainer container = new DefaultMessageListenerContainer();
  container.setAutoStartup(true);
  container.setConnectionFactory(mqConnectionFactory);
  container.setDestinationName(//queue name//);
  container.setMessageListener(new MyEventListener());
  return container;
}

2：实现消息侦听器：

public class MyEventListener implements MessageListener {

  @Override
  public void onMessage(Message message) {
    try {
      if (message instanceof TextMessage) {
        TextMessage textMessage = (TextMessage) message;
        String stringMessage = textMessage.getText();
        //do something with your message from queue
      }
    } catch (JMSException e) {
      //catch error
    }
  }
}

Answer 2

在pom中添加“mq jms spring boot starter”依赖项。xml格式如下：

在应用程序中添加以下属性。亚马尔：

  mq:
    queue-manager: queueManager
    conn-name: connName(port)
    channel: channelName
    ssl-cipher-suite: TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 or whatever ur app supports
    use-i-b-m-cipher-mappings: true (if using topic otherwise skip this property)

将下面的注释@JmsListener添加到侦听器方法中

@EnableJms
Public class Consumer{
   @JmsListener(destination = "QueueNameToListenTo")
    public void listener(Object message) {
       logger.info("message received {}",message);
       //do something
    }
}
