java.rmi.server.ExportException: internal error: ObjID already in use報錯處理

因爲在server.xml文件中使用配置了
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"  rmiRegistryPortPlatform="12340" rmiServerPortPlatform="12340"/>
在catalina.sh中也指定了對應
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12340 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.40.103"這裏設置了對應的設置

解決辦法
把文件server.xml中的
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"  rmiRegistryPortPlatform="12340" rmiServerPortPlatform="12340"/>
刪除便可
