java - Spring Boot多个JMS连接

Question

我正在开发Spring Boot应用程序，该应用程序必须连接到具有不同端口甚至IP地址的多个WebSphere JMS连接。我需要将消息发送和发送到不同的队列。
我以来自此来源的连接为例-https://github.com/lzp4ever/IBM_WebSphere_MQ_Spring_Boot_JMS
但是，当我添加第二个连接时，Spring Boot无法启动，只是不知道使用哪个。
我的问题是我应该如何配置我的配置文件以监听多个队列？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)，然后添加Bean(name)来分开它们。它不起作用，然后我向每个配置文件添加了新的JmsListenerContainerFactory bean。
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;
}

然后我从此更改我的发件人代码:

@Autowired
private JmsOperations jmsOperations;

对此

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

我也将接收器更改为:

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

在我看来，它有效!!!
但是我的CachingConnectionFactory之一必须标记为@Primary。如果我从一个配置文件中删除@Primaty，那么我就是gettig这个错误:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.2018-03-28 12:28:37 -

申请启动失败

Description:

Parameter 1 of method myFactory in com.config.UzbConnection required a bean of type 'org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer' that could not be found.

Action:

Consider defining a bean of type 'org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer' in your configuration.
