如何使用 spring 连续启动从 IBM MQ JMS 接收消息？

Question

我有 spring 启动应用程序，它接收 JSON 请求并将其推送到 IBM MQ JMS 队列。可以有 n 个 JSON 个请求将被推送到队列中。我的目标是处理队列中的每个请求。我如何收听队列并使用 spring 引导一条一条地获取消息以进行处理？

Answer 1

您需要将侦听器实现为：

1：创建配置如下：

@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：实现消息监听器：

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.xml中添加'mq-jms-spring-boot-starter'依赖如下：

在 application.yaml 中添加以下属性：

  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)

在您的侦听器方法中添加以下注解@JmsListener

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