Spring Boot 多个 JMS 连接

Question

我正在开发 Spring Boot 应用程序，它必须连接到具有不同端口甚至 IP 地址的多个 WebSphere JMS 连接。我需要接收和发送消息到不同的队列。

我从这个源中获取了连接示例 - https://github.com/lzp4ever/IBM_WebSphere_MQ_Spring_Boot_JMS

但是当我添加第二个 connectionFactory Spring Boot 无法启动时，它只是不知道使用哪个一次。

我的问题是我应该如何配置我的配置文件来监听多个队列？将 SpringBoot 应用程序连接到几个不同的 JMS 服务器是个好主意吗？

解决方案

我只是第二次复制并粘贴相同的bean（如上面的git链接）并添加Bean（名称）来分隔它们。这是行不通的，然后我将新的 JmsListenerContainerFactory bean 添加到我的每个配置文件中。

我的配置文件之一是：

@Bean(name = "mqQueueConnectionFactory2")
public MQQueueConnectionFactory mqQueueConnectionFactory2() {
    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) {
        logger.error("MQQueueConnectionFactory bean exception", e);
    }
    return mqQueueConnectionFactory;
}

@Bean(name = "userCredentialsConnectionFactoryAdapter2")
UserCredentialsConnectionFactoryAdapter userCredentialsConnectionFactoryAdapter2(@Qualifier("mqQueueConnectionFactory2") MQQueueConnectionFactory mqQueueConnectionFactory) {
    UserCredentialsConnectionFactoryAdapter userCredentialsConnectionFactoryAdapter = new UserCredentialsConnectionFactoryAdapter();
    userCredentialsConnectionFactoryAdapter.setUsername(username);
    userCredentialsConnectionFactoryAdapter.setPassword(password);
    userCredentialsConnectionFactoryAdapter.setTargetConnectionFactory(mqQueueConnectionFactory);
    return userCredentialsConnectionFactoryAdapter;
}

@Bean(name = "cachingConnectionFactory2")
//@Primary
public CachingConnectionFactory cachingConnectionFactory2(@Qualifier("userCredentialsConnectionFactoryAdapter2") UserCredentialsConnectionFactoryAdapter userCredentialsConnectionFactoryAdapter) {
    CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
    cachingConnectionFactory.setTargetConnectionFactory(userCredentialsConnectionFactoryAdapter);
    cachingConnectionFactory.setSessionCacheSize(500);
    cachingConnectionFactory.setReconnectOnException(true);
    return cachingConnectionFactory;
}

@Bean(name = "jmsTransactionManager2")
public PlatformTransactionManager jmsTransactionManager2(@Qualifier("cachingConnectionFactory2") CachingConnectionFactory cachingConnectionFactory) {
    JmsTransactionManager jmsTransactionManager = new JmsTransactionManager();
    jmsTransactionManager.setConnectionFactory(cachingConnectionFactory);
    return jmsTransactionManager;
}

@Bean(name = "jmsOperations2")
public JmsOperations jmsOperations2(@Qualifier("cachingConnectionFactory2") CachingConnectionFactory cachingConnectionFactory) {
    JmsTemplate jmsTemplate = new JmsTemplate(cachingConnectionFactory);
    jmsTemplate.setReceiveTimeout(receiveTimeout);
    return jmsTemplate;
}

@Bean
public JmsListenerContainerFactory<?> myFactory2(@Qualifier("cachingConnectionFactory2") CachingConnectionFactory connectionFactory,
                                                 DefaultJmsListenerContainerFactoryConfigurer configurer) {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    // This provides all boot's default to this factory, including the message converter
    configurer.configure(factory, connectionFactory);
    // You could still override some of Boot's default if necessary.
    return factory;
}

然后我更改我的发件人代码：

@Autowired
private JmsOperations jmsOperations;

对此

@Autowired
@Qualifier("jmsOperations2")
private JmsOperations jmsOperations;

我还将接收器更改为：

@JmsListener(destination = "${project.queues.uzb.recieve}", containerFactory = "myFactory2")
public void receiveMessage(JMSTextMessage data) {
    
}

在我看来它有效！

但我的 CachingConnectionFactory 之一必须标记为 @Primary。如果我从我的配置文件之一中删除@Primaty，那么我会收到此错误：

启动 ApplicationContext 时出错。要显示条件报告，请在启用“调试”的情况下重新运行应用程序。2018-03-28 12:28:37 -

应用程序无法启动

描述：

com.config.UzbConnection 中方法 myFactory 的参数 1 需要类型为“org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer”的 bean，但无法找到。

行动：

考虑在配置中定义“org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer”类型的 bean。

谢谢
