ActiveMQ嵌入式代理，关机挂钩中的异常 [英] ActiveMQ embedded broker, exception in shutdown hook

问题描述

使用嵌入式代理在关机时出现以下错误:

I get the following error on shutdown, using an embedded broker:

Exception in thread "ActiveMQ ShutdownHook" java.lang.NoClassDefFoundError: org/apache/activemq/broker/BrokerService

我可能配置有误吗?我使用了activemq页面上的配置:

Have I misconfigured something possibly? I used the config spelled out on the activemq page here:

http://activemq. apache.org/how-do-i-embed-a-broker-inside-a-connection.html

(底部标记为"using spring-2.0"的配置).邮件已正确传递，等等.因此，我不确定此错误是否无害.

(the configuration labeled "using spring-2.0" at the bottom). The messages are being delivered properly etc. so I'm not sure if this error is harmless.

推荐答案

这是一个老问题，当ActiveMQ嵌入并且未正确配置为100％时，可能会发生.链接的配置中唯一遗漏的是将useShutdownHook="false"添加到XML配置的<broker>元素中.下面是一个简单的示例:

This is an old issue that can occur when ActiveMQ is embedded and not configured 100% correct. The only thing that is left out in the config you linked is to add useShutdownHook="false" to the <broker> element of the XML config. Below is a quick example:

<amq:broker useJmx="false" persistent="false" useShutdownHook="false">
...
</amq:broker>

这将禁用关闭挂钩，并防止出现此问题.

This will disable the shutdown hook and prevent this problem from occurring.
