problem

restart jeecg Of tomcat after , The above error , function netstat -tunlp |grep 40001 Service found , But check it out pid We can't find it

find ./ -name ehcache.xml

2: edit ehcache.xml file , find cacheManagerPeerListenerFactory node
take 40001 Just change it port, preservation , It's over
