当我关闭tomcat时，我在日志中收到这些消息，而JVM不会释放该进程：
Jan 16, 2015 4:20:25 PM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
SEVERE: The web application [/myproject] appears to have started a thread named [SimpleAsyncTaskExecutor-1] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/myproject] appears to have started a thread named [pool-1-thread-1] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/myproject] appears to have started a thread named [pool-1-thread-2] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: The web application [/myproject] appears to have started a thread named [pool-1-thread-3] but has failed to stop it. This is very likely to create a memory leak.

我使用调试器来查看这些线程在关闭之前做了什么，这是他们的一个线程转储：

我用这个作为春/兔负责这个问题的证据。
这是我的Spring上下文中与rabbit mq：
有关的部分<rabbit:connection-factory id="connectionFactory" host="host" port="5672" username="username" password="password" virtual-host="/projectname"/>
<rabbit:admin connection-factory="connectionFactory"/>
<rabbit:template id="amqpTemplate" connection-factory="connectionFactory" exchange="barExchange"/>
<rabbit:queue name="barQueueCleanDev" />
<rabbit:queue name="barQueueFooDev" />
<rabbit:topic-exchange name="barExchange" >
<rabbit:bindings>
<rabbit:binding queue="barQueueFooDev" pattern="bar.queue.foo.dev" />
<rabbit:binding queue="barQueueCleanDev" pattern="bar.queue.clean.dev" />
</rabbit:bindings>
</rabbit:topic-exchange>
<rabbit:listener-container connection-factory="connectionFactory" acknowledge="auto" concurrency="1" max-concurrency="1" requeue-rejected="false" error-handler="barServiceErrorHandler">
<rabbit:listener ref="barService" method="create" queue-names="barQueueCleanDev"/>
<rabbit:listener ref="barService" method="createFromFoo" queue-names="barQueueFooDev"/>
</rabbit:listener-container>
当我关闭tomcat时，如何告诉spring-rabbit停止创建的线程？
我正在使用spring-rabbit版本1.4.2.RELEASE
答案 0 :(得分：0)
我通过在servlet的destroy方法中手动调用我的Spring applicationContext.destroy()来解决这个问题。
