Springboot start error: protocol handler start failed

Problem Description:
in the process of migrating the old project functions to the new reconstructed project, the protocol handler start failed error is reported when starting the new reconstructed project 👇

Protocol handler start failed

Error reason:
port number conflict

The problem is that the Eureka is started when the old project is started to view the interface data. When the new project is started, the Eureka of the old project is not closed, but another Eureka is re opened, resulting in port conflict.

Close Eureka of the old project!
