Unable to open debugger port (127.0.0.1:49897): java.net.SocketException "Socket closed"
I don't understand the specific reason, my solution steps:
1、tomcat shutdown.bat
2、tomcat startup.bat
3、IntelliJ IDEA restart
4. Modify the JMX Port in the configuration
5. Modify Debug Prot
6、mvn clean
It's normal when I debug it again. I don't know what works. Let's play it one by one.
