IBM WebSphere MQ8.0 发送和接收消息

本文使用springboot集成IBM MQ的客户端, 简单的实现消息接收和发送逻辑.

pom依赖

  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jms</artifactId>
  </dependency>

  <dependency>
    <groupId>javax.jms</groupId>

配置文件

这里的配置和上文中创建的队列信息一致

server.port=9111
## mq的连接ip
project.mq.host=192.168.0.106
## mq的连接端口
project.mq.port=1414
## mq的队列管理器名字
project.mq.queue-manager=QM144
## mq的java客户端连接通道
project.mq.channel=SYSTEM_DEF_SVRCONN
## mq的用户名
project.mq.username=mqm
## mq的密码
project.mq.password=Paic2023q2
## mq的接收超时时间
project.mq.receive-timeout=20000
## 收发队列名称（可选）
project.mq.queuename=QUEUE1

配置类

@Configuration
public class JmsConfig {
    @Value("${project.mq.host}")
    private String host;
    @Value("${project.mq.port}")
    private Integer port;
    @Value("${project.mq.queue-manager}")
    private String queueManager;
    @Value("${project.mq.channel}")
    private String channel;
    @Value("${project.mq.username}")
    private String username;
    @Value("${project.mq.password}")
    private String password;
    @Value("${project.mq.receive-timeout}")
    private long receiveTimeout;
    @Bean
    public MQQueueConnectionFactory mqQueueConnectionFactory() {
        MQQueueConnectionFactory mqQueueConnectionFactory = new MQQueueConnectionFactory();
        mqQueueConnectionFactory.setHostName(host);
        try {
            mqQueueConnectionFactory.setTransportType(WMQConstants.WMQ_CM_CLIENT);
            mqQueueConnectionFactory.setCCSID(1208);
            mqQueueConnectionFactory.setChannel(channel);
            mqQueueConnectionFactory.setPort(port);
            mqQueueConnectionFactory.setQueueManager(queueManager);

        } catch (Exception e) {
            e.printStackTrace();
        }
        return mqQueueConnectionFactory;
    }
    @Bean
    UserCredentialsConnectionFactoryAdapter userCredentialsConnectionFactoryAdapter(MQQueueConnectionFactory mqQueueConnectionFactory) {
        UserCredentialsConnectionFactoryAdapter userCredentialsConnectionFactoryAdapter = new UserCredentialsConnectionFactoryAdapter();
        userCredentialsConnectionFactoryAdapter.setUsername(username);
        userCredentialsConnectionFactoryAdapter.setPassword(password);
        userCredentialsConnectionFactoryAdapter.setTargetConnectionFactory(mqQueueConnectionFactory);
        return userCredentialsConnectionFactoryAdapter;
    }
    @Bean
    @Primary
    public CachingConnectionFactory cachingConnectionFactory(UserCredentialsConnectionFactoryAdapter userCredentialsConnectionFactoryAdapter) {
        CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
        cachingConnectionFactory.setTargetConnectionFactory(userCredentialsConnectionFactoryAdapter);
        cachingConnectionFactory.setSessionCacheSize(500);
        cachingConnectionFactory.setReconnectOnException(true);
        return cachingConnectionFactory;
    }
    @Bean
    public PlatformTransactionManager jmsTransactionManager(CachingConnectionFactory cachingConnectionFactory) {
        JmsTransactionManager jmsTransactionManager = new JmsTransactionManager();
        jmsTransactionManager.setConnectionFactory(cachingConnectionFactory);
        return jmsTransactionManager;
    }
    @Bean
    public JmsOperations jmsOperations(CachingConnectionFactory cachingConnectionFactory) {
        JmsTemplate jmsTemplate = new JmsTemplate(cachingConnectionFactory);
        jmsTemplate.setReceiveTimeout(receiveTimeout);
        return jmsTemplate;
    }
}

发送消息

    public void sendMq(@RequestParam String msg) {
        log.info("获得报文并开始向mq发送："+msg);

        jmsTemplate.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
        jmsTemplate.setExplicitQosEnabled(true);
        jmsTemplate.send("QUEUE1", session -> {
            TextMessage m = session.createTextMessage();
            m.setText(msg);
            m.setJMSCorrelationID("1111");
            return m;
        });

//        Message message = jmsTemplate.receiveSelected("QUEUE1", "JMSCorrelationID='2222'");
//        System.err.println("---->" + message.toString());

        log.info("======推送mq报文完成======");
    }

接收消息

@Slf4j
@Component
public class MQListener extends MessageListenerAdapter {
    @Autowired
    JmsOperations jmsOperations;

    @Autowired
    private JmsTemplate jmsTemplate;

    @Override
    @JmsListener(destination = "${project.mq.queuename}", selector = "JMSCorrelationID='1111'")
    public void onMessage(Message message) {
        log.info("从MQ接收的message报文:"+message);


        jmsTemplate.send("QUEUE1", session -> {
            TextMessage m = session.createTextMessage();
            m.setText("return data");
            m.setJMSCorrelationID("2222");

            return m;
        });
    }

}
