我的应用程序使用嵌入了TomEE Plus-8.0.0-M1的ActiveMQ。
耗尽池连接的行为是相同的,而不管使用使用resources.xml的显式定义的javax.jms.ConnectionFactory还是让TomEE即时生成一个。
连接超时的不同设置似乎没有效果:
connectionMaxIdleTime = 3 seconds
connectionMaxIdleTime = 15 minutes
如果ExampleSessionBean.sendMessage()被顺序调用11次,则“废弃的连接”警告将记录在消息1-10上。在消息#11上,抛出JMSRuntimeException:没有可用的托管连接。
然后,如果我等待几分钟,JMSContext生产者将能够再次发送。
我首先想到的是,需要使用以下命令关闭JMSContext中的基础连接
jmsContext.close();
但来自Interface JMSContext
“如果JMSContext是容器管理的(注入),则不得使用此方法。”
这里需要哪些编程或配置更改?
谢谢,
特德

警告-消息1-10 :(请原谅格式化。SE格式化程序由于某种原因不会格式化此文本块)
开始警告文字
警告:事务已完成,但是连接仍然具有关联的句柄:ManagedConnectionInfo:
... org.apache.openejb.resource.activemq.jms2.cdi.JMS2CDIExtension $ InternalJMSContext.createProducer(JMS2CDIExtension.java:370),com.myorg.jms.ExampleSessionBean.sendMessage(ExampleSessionBean.java:46),
...
结束警告文字
讯息#11异常

更新:此行为已被复制并添加到TomEE issues tracker。
最佳答案
我放弃了JMSContext并回到手动管理连接。即使加载了数百条消息,所有功能也会按预期运行。
