CodePudding user response：

The exception stack trace(startup trace) shows that your tomcat did not started due to port 8080 already in use:

Address already in use: bind <null>:8080

Also try start your tomcat:

mvn tomcat:run -Dmaven.tomcat.port=8081

CodePudding user response：

when i use this command what u write mvn tomcat:run -Dmaven.tomcat.port=8081, doesnt work.
