如何配置 Artemis ActiveMQ 以使用 AMQP 1.0 和其他 Java 协议

Question

我有一个 Artemis 服务器，运行良好。我现在想在服务器上为使用 pub-sub 的节点应用程序启用 AMQP。虽然我的节点发布订阅服务器能够连接到它，但即使连接有效，它们也不会发布或接收。为什么我的 pub 不发送/为什么我的 sub 不接收？

我正在关注 Github 上 AMQP Rhea 的 publisher 和 5 个 subscriber 示例。它们都可以连接到 localhost:5672。

下面是我的 Artemis JMS 服务器实现。请注意，我使用 addAcceptorConfiguration 添加了 2 个配置（一个用于 Artemis，另一个用于 AMQP 的默认端口）。

您需要为接受方配置启用的协议，因为它们不会根据您提供的名称推断其角色。您可以为每个接受器启用多个协议或根据您的用例限制它。

config.setPersistenceEnabled(false)
      .setSecurityEnabled(false)
      .addAcceptorConfiguration("tcp", "tcp://localhost:61616")
      .addAcceptorConfiguration("amqp", "tcp://localhost:5672?protocols=CORE,AMQP");
