我正在尝试使用 java 8 jre （服务器地址：192.168.10.3）对我的 tomcat 9 进行 jconsole 远程监控。在 tomcat9w 中我有这个 java 选项：
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=5000
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.local.only=false
-Djava.rmi.server.hostname=192.168.10.3
防火墙已关闭。
带 -debug 的 Jconsole 向我展示了这一点：
