There are two possible reasons for a problem resolution:

• 1. Eureka Dependency not introduced
• [email protected] The name is wrong in the note, such as this time I follow the tutorial as a name to write App1, it is not ...

1. Introduction of dependency

        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-eureka</artifactId>        </dependency>

2. Modify the name of the correct spring.application.name for the invoked service
