Disconnected from the target VM, address: '127.0.0.1:56150', transport: 'socket'

Process finished with exit code -1

Solution:
refer to this link

When debug starts the Spring boot project, the project does not start. The last line of the log shows Disconnected from the target VM, address: '127.0.0.1:51458', transport: 'socket'.

Seeing this, the first feeling is that the port is occupied.

1. To solve the problem of port occupancy, first check the startup status of the port

Win+R Enter cmd to open the DOS command box. Type: netstat -ano | findstr 8060 where 8060 is the port number of my service.

If this is displayed, it means that the background port 8060 is still running, and the PID is 10316. Kill the port process and restart the program.

2. Kill the process, choose one of two methods:

1. ctrl + alt + delete, start the task manager, find the corresponding process according to the PID (that is, 10316 above), right-click on the end task (E)

2. According to tasklist | findstr 10316. What program is occupying port 8060 when querying. Among them, 10316 is the PID queried above.

Then continue to execute taskkill /f /t /im java.exe directly
