當JAVA_HOME指向JRE時，無法使用activemq-admin.bat停止JMS代理1.8

Question

當JAVA_HOME指向JRE（1.8.111）時，我無法使用activemq-admin.bat腳本停止JMS代理。使用JDK時不會出現該問題。 在腳本的ACTIVEMQ_SUNJMX_START參數被註釋掉和默認端口改爲61099這樣的：

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

不知怎的，它的端口看起來被忽略......

我們是否需要一個JDK停止經紀人？ 任何想法？

Answer 1

這是因爲ActiveMQ的使用Java Attach API自動發現JMX URL。要使用此API，類將從$JAVA_HOME\..\lib\tools.jar加載。由於tools.jar是JDK（參見JDK files）的一部分，因此對於JRE（不是JDK $JDK_HOME\jre附帶的JRE）將會失敗。

要使用JRE停止代理，您必須提供JMX URL。

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

連接消息看起來像

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