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

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时不会出现该问题。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，该端口似乎被忽略了......

我们需要 JDK 来停止代理吗？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，请从 $JAVA_HOME\..\lib\tools.jar 加载类。 。如tools.jar是 JDK 的一部分(请参阅 JDK files )，这对于 JRE(不是 JDK $JDK_HOME\jre 附带的 JRE)将会失败。

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

连接消息如下所示
