"Address already in use" means, there is already another application running on port 8080. Use your OS tools to find that process and end it, before you start your application, or let your application run on another port. If you use an embedded server in your Boot application, you can specify the following property:

server.port=8085

Of course you can choose whatever port you want.

这段的意思大致是在application.properties文件中加上一句server.port=8085
