spring - 如何在 Spring 的 applicationContext 中设置 JMS 配置？

Question

如何为下面给出的 java 代码设置应用程序？

Hashtable<String, String> properties = new Hashtable<String, String>();
            properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.test.factory");
            properties.put("com.domain", "DevelopmentDomain");
//            properties.put(Context.PROVIDER_URL, "tcp://test:0506");
            properties.put(Context.PROVIDER_URL, "tcp://10.00.0.00:0506");


            properties.put(Context.SECURITY_PRINCIPAL, "aaa");
            properties.put(Context.SECURITY_CREDENTIALS, "aaa");

            javax.naming.Context context = new javax.naming.InitialContext(properties);
            ConnectionFactory factory = (ConnectionFactory) context.lookup("ImpactPocQueueConnectionFactory");

            Connection connection = factory.createConnection();

            connection.start();

            Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

            Destination queue = session.createQueue("test.producer");

我在这里和那里看到了很多例子，但没有一个给出完整的画面。

如果您想将此代码逐字转换为 Spring 配置，请考虑利用 @Configuration方法:

@Bean
public Destination queue() throws JMSException, NamingException {
    return session().createQueue("test.producer");
}

@Bean
public Session session() throws JMSException, NamingException {
    return connection().createSession(false, Session.AUTO_ACKNOWLEDGE);
}

@Bean(initMethod = "start")
public Connection connection() throws JMSException, NamingException {
    return connectionFactory().createConnection();
}

@Bean
public ConnectionFactory connectionFactory() throws NamingException {
    return (ConnectionFactory) context().lookup("ImpactPocQueueConnectionFactory");
}

@Bean
public Context context() throws NamingException {
    return new javax.naming.InitialContext(properties());
}

@Bean
public Hashtable<String, String> properties() {
    Hashtable<String, String> properties = new Hashtable<String, String>();
    properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.test.factory");
    properties.put("com.domain", "DevelopmentDomain");
    //properties.put(Context.PROVIDER_URL, "tcp://test:0506");
    properties.put(Context.PROVIDER_URL, "tcp://10.00.0.00:0506");
    properties.put(Context.SECURITY_PRINCIPAL, "aaa");
    properties.put(Context.SECURITY_CREDENTIALS, "aaa");
    return properties;
}

从技术上讲，您可以使用 XML 完成所有这些工作，但我发现这种方法更具可读性和可维护性。现在你有 connectionFactory和 queue范围内可用的 bean 类。您可以轻松地与 Spring JMS support 集成.如果您需要进一步的帮助，请告诉我们。
