Question

Java JMS客户端应用程序需要哪一组jar才能发布消息。我的课程路径上有 activemq-client-5.13.3.jar 。但是还不够，而且越来越

'Exception in thread "main" java.lang.NoClassDefFoundError: 
javax/management/j2ee/statistics/Stats'.

注意：-在添加'activemq-all' jar时。它将正常工作，但是我不想添加这些多个jar，因为它大约为17MB。

 Connection connection = null;

        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_BROKER_URL);
        connection = connectionFactory.createConnection();
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        Topic topic = session.createTopic("customerTopic");

        connection.start();

        String payload = "Important task";
        Message msg = session.createTextMessage(payload);
        MessageProducer producer = session.createProducer(topic);
        producer.send(msg);
        Thread.sleep(3000);
        session.close();

        if(connection != null) {
            connection.close();
        }
    }

一种简单的查找方法是将maven与ActiveMQ source code一起从git中检出。移至activemq-client项目文件夹，并要求Maven生成依赖关系树mvn dependency:tree

在您的情况下，您可以切换到5.13.3的发行版标签以获取确切的列表，尽管我认为自该发行版以来它并没有太大变化。当然，如果您使用maven构建项目，那么也可以从项目目录中进行操作，它会为您提供整个项目的依赖树。
