Question

当JAVA_HOME指向JRE（1.8.111）时，我无法使用activemq-admin.bat脚本停止JMS代理。使用JDK时不会出现此问题。在脚本中，ACTIVEMQ_SUNJMX_START参数被取消注释，默认端口更改为61099，如下所示：

"set ACTIVEMQ_SUNJMX_START=-Dcom.sun.management.jmxremote.port=61099 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"

不知何故，端口看起来被忽略了......

我们需要JDK来阻止经纪人吗？有什么想法吗？

Answer 1

这是因为ActiveMQ使用Java Attach API自动发现JMX URL。要使用此API，将从$JAVA_HOME\..\lib\tools.jar加载类。由于tools.jar是JDK的一部分（请参阅JDK files），因此JRE（而不是JDK $JDK_HOME\jre附带的JRE）将失败。

要使用JRE停止代理，您必须提供JMX URL。

set ACTIVEMQ_OPTS=-Dactivemq.jmx.url=service:jmx:rmi:///jndi/rmi://localhost:61099/jmxrmi
activemq-admin.bat stop

连接消息看起来像

Connecting to JMX URL: service:jmx:rmi:///jndi/rmi://localhost:61099/jmxrmi

当JAVA_HOME指向JRE 1.8时，无法使用activemq-admin.bat停止JMS代理
