Spring JmsTemplate 和 Apache ActiveMQ，为什么有这么多连接？
我有一个 Web 应用程序，一旦在 ActiveMQ 上收到消息（由 Spring MessageListener 侦听），该应用程序就会在后台运行文本处理作业......我遇到的问题是，一旦我处理大约 30 个后台作业，ActiveMQ停止处理任何消息，Spring 消息侦听器丢失其 JMS 连接，有时我在 ActiveMQ 日志中收到错误消息，指出
我在 Linux 上针对 ActiveMQ 进程运行了“lsof”（列出打开文件）命令 。并注意到对于 JmsTemplate 排队/发布/接收的几乎每条消息，都会打开一个新连接，这
是我的配置吗？
<bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
<constructor-arg ref="amqConnectionFactory" />
<property name="exceptionListener" ref="jmsExceptionListener" />
<property name="sessionCacheSize" value="100" />
</bean>
I have a web application that runs text processing jobs in the background once a message is received on an ActiveMQ which is listened to by a Spring MessageListener....the problem I"m encountering is that once I process around 30 background jobs, ActiveMQ stops processing any messages, Spring message listener loses its JMS connection, and sometimes I get an error in the ActiveMQ log saying that there are too many open files.
I ran the 'lsof' (list open file) command on Linux against the ActiveMQ process and noticed that for almost each message queued/published/received by JmsTemplate, a new connection is opened. Is this normal?
here's my configuration:
<bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
<constructor-arg ref="amqConnectionFactory" />
<property name="exceptionListener" ref="jmsExceptionListener" />
<property name="sessionCacheSize" value="100" />
</bean>

需要使用ActiveMQ提供的PooledConnectionFactory，完整配置可以这里查看< /a>.请务必阅读 JmsTemplate 陷阱。
You need to use the PooledConnectionFactory provided by ActiveMQ, you can see full configuration here. Make sure you read the JmsTemplate Gotchas as well.
