Question

我一直在试图解决这个问题，我需要一个不同的视角。我正在使用spring并且已经合并了这个spring boot starter pack，以便我可以利用AMQP协议： amqp-10-jms-spring-boot-starter 我已成功配置并且目前有工作。当我将其部署到Jboss eap7 Container＆＃34; 这是一个需求＆＃34;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。当我在没有先取下容器的情况下重新部署相同的应用程序时，问题就出现了（我不应该这样做）。以下是我迄今为止所考虑和尝试的内容：

春天的东西是不是正确清理了？ 查看一些JMC飞行计划员统计数据并且看不到任何内容那个跳出来对我说。没有Springframework或JMSConnectionFactory实例遗留下来。
Wildlfy Classpath问题？我在jboss-deployment中忽略了artemis libs和artemis模块
好朋友谷歌 99％的本垒打时间。这次虽然方向不多。

JBoss的部署结构

<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，我在这里有其他代码，包括JSR包，Hibernate，spring-web等依赖项。为了完整，我留下了那些。

没有什么能让我抓住这里的稻草。所以任何方向都有帮助。我可以使用JMS API，我稍后会尝试。但我希望能把这一点弄清楚。提前谢谢。

更新

我把所有代码都排除在外，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以某种方式以某种方式干扰（无论是使用Jboss还是直接干扰）并保持差事连接。

Answer 1

我认为这与JBOSS类加载机制有关。当我们从WLS迁移到JBOSS时，我们经历了几个奇怪的问题。建议您在应用程序启动时使用Class.forName实例化所需的驱动程序类/库。您可以尝试的另一个方法是删除standalone.xml / domain.xml中的子系统包含（子系统xmlns =“urn：jboss：domain：messaging-activemq：1.0”）并检查。希望这会有所帮助。

Answer 2

好吧我发现了这个问题。记下我将此应用程序移动到Tomcat后才发现核心问题。其中说“你创建了一个没有被删除的线程”。我的代码使用AsynchronousSocketChannel类，我用它来监听我关心的端口。默认实现使用类AnsychronousChannelGroup，在这种情况下不会被清理，一旦将通道组分配给套接字通道，就可以通过这种方式清理线程。我将在今天晚些时候将我的代码上传到github帐户，以便可以使用它。 Java 8 Bug？
