the reason
Environmental abnormal restart, project java process is not closed, the port in the original project is still occupied.
Typically 8080 port is occupied
Solution
The following two methods can be resolved, the same principle (abnormal end process)
1. simple and crude:
Open the Task Manager process to find java, java process will shut down and restart the bin!
2. Easy instruction REVISION (boring can toss)
- Cmd to open a command window, enter the following command to see all ports and PID
netstat -ano
- Find the port corresponding PID input commands to find the corresponding process
tasklist | findstr "7676"
- Kill the process restarted get away!
taskkill / f / t / im java.exe
