javax.jms.JMSException: 现有连接被远程主机强行关闭
javax.jms.JMSException: An existing connection was forcibly closed by the remote host
我是一个新手，正在尝试将 qpid 与 Apache Camel 集成。我需要编写 java 代码以使用 qpid.
从队列中读取和写入
所以我首先从qpid 网站下载了JMS 示例。我正在尝试 运行 的代码是。

为什么会出现这个错误？而这个端口肯定在我的本地机器上监听。同样，我是 JMS 的新手，因此非常感谢任何指导:)
看起来您可能正在使用 Qpid JMS AMQP v1.0 client，它将无法连接到 RabbitMQ，除非您使用 RabbitMQ 的实验性 AMQP 1.0 插件。
确保您使用的客户端与您所在的经纪商兼容 运行。
正如 Tim 提到的，您至少还需要确保加载了代理实验性 AMQP 1.0 插件，但您没有提到这样做。
但是，在这种情况下，它可能没有太大区别。我之前使用 JMS 客户端或其他一些 AMQP 1.0 客户端对付 RabbitMQ 并没有取得多大成功，因为我报告了一个问题，该问题在创建消费者和生产者时阻止了它们：https://github.com/rabbitmq/rabbitmq-amqp1.0/issues/34
您提到过研究决定使用 RabbitMQ 的事情，这听起来好像您不受现有服务器解决方案的束缚？如果是这样，对于其他支持 AMQP 1.0 且经常使用 JMS 客户端的服务器，您可以尝试 ActiveMQ、ActiveMQ Artemis、Qpid for Java broker、Qpid C++ broker 或 Qpid Dispatch router（不适用于Windows，你提到使用），等等。
