java - 无法将 org.apache.qpid.jms.provider.amqp.AmqpProviderFactory 转换为 org.apache.qpid.jms.provider.ProviderFactory

Question

我一直在努力解决这个问题，现在需要一个不同的视角。我正在使用 spring 并合并了这个 spring boot 启动包，这样我就可以利用 AMQP 协议(protocol):amqp-10-jms-spring-boot-starter 我已经成功配置并且目前有在职的。当我将其部署到 Jboss eap7 容器“THIS A REQ”时，问题就出现了。所以当我第一次部署这个应用程序时，一切都很好。当我在没有先关闭容器的情况下重新部署同一个应用程序时，问题就出现了(因为我不应该这样做)。到目前为止，这是我想到和尝试过的:

1. spring 中的某些东西没有被正确清理？ 查看一些 JMC 飞行计划统计数据，但没有看到任何东西 这让我大吃一惊。没有剩余的 Springframework 或 JMSConnectionFactory 实例。
2. Wildlfy Classpath 问题？ 我在我的 jboss-deployment 中忽略了 artemis 库和 artemis 模块
3. Good Friend google 99% 的时间都是本垒打。这次虽然方向不多。

Jboss 部署结构

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <deployment>
        <exclude-subsystems>
            <subsystem name="jaxrs" />
            <subsystem name="messaging-activemq" />
        </exclude-subsystems>
        <exclusions>
            <module name="org.hibernate" slot="main" />
            <module name="org.apache.activemq.artemis" slot="main" />
            <module name="org.apache.activemq.artemis.ra" slot="main" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

请记住，我这里还有其他代码，包括 JSR 包、Hibernate、spring-web 等依赖项。为了完整起见，我留下了这些。

没有什么能帮助我在这里捕获救命稻草。所以任何方向都是有帮助的。我可以只使用 JMS API，我稍后会尝试。但我希望弄清楚这一点。提前致谢。

更新

我将我所有的代码都从方程式中取出并创建了一个简单的服务。 amqp-10-jms-spring-boot-starter 不是罪魁祸首。我怀疑我的 Spring 事件监听器或我的 AsynchronousSocketChannel 以某种方式干扰(通过 Jboss 或直接)并保持差事连接。

Answer 1

好的，我发现了这个问题。请注意，我将此应用程序移至 Tomcat 后才发现核心问题。其中指出“您创建了一个未被删除的线程”。我的代码使用我用来监听我关心的端口的 AsynchronousSocketChannel 类。默认实现使用 AnsychronousChannelGroup 类，在这种情况下它不会被清理，一旦你将一个 channel 组分配给你的 socketchannel，你就可以用这种方式清理线程。我将在今天晚些时候将我的代码上传到一个 github 帐户，以便人们可以使用它。 Java 8 错误？
