I read a lot of posts on the Internet but did not solve my problem.

Finally deleted the pom packaging method to solve the problem. I have to say that it is really disgusting

pom packaging

Other possible problems
Want to join this

client:
     register-with-eureka: false #Whether to register yourself in eureka
     fetch-registry: false #Whether to get information from eureka

Finally, attach my application.yml code

server:
   port: 7001
eureka:
   instance:
     hostname: 127.0.0.1
   client:
     register-with-eureka: false #Whether to register yourself in eureka
     fetch-registry: false #Whether to get information from eureka
     service-url:
       defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
