I use in the project to develop a real-time refresh for springmvc + mybatis project, in the local test front-end and back-end can be normal use, Linux server in the company post test can normal visit, but on the client/server deployment operation access error, due to the server is the client, only through the network access,

The front-end error:

 
Firefox cannot be established to ws://web address/project name/websocket server connection, 
The Close mySocket finish... 

Backstage, error log is as follows:
