After all the project dependencies are loaded , Add... To the startup class @EnableDiscoveryClient, Declare that this is a eureka client, Otherwise, there will be no service registration ：

1. package org.zero.eureka.client;

3. import org.springframework.boot.SpringApplication;

4. import org.springframework.boot.autoconfigure.SpringBootApplication;

5. import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

9. public class ClientApplication {

11. public static void main(String[] args) {

12. SpringApplication.run(ClientApplication.class, args);

13. }

And then there was application.yml In profile , The configuration registry is eureka server The address of , And the name and boot port number of the project . as follows ：

1. eureka: 

3. service-url:

4. defaultZone: http://localhost:8761/eureka/

5. spring:

6. application:

7. name: eureka-client

8. server:

9. port: 9088

After completing the above configuration , Start the project . But I failed when I started the project here , The console outputs the following warning message ：

Invocation of destroy method failed on bean with name 'scopedTarget.eurekaClient': org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'eurekaInstanceConfigBean': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

This is because client It doesn't contain Tomcat Dependence , therefore Spring The container was unable to create some instances , As a result, the project cannot be started , Just in pom.xml In file , add web Rely on it ：

1. <dependency>

2. <groupId>org.springframework.boot</groupId>

3. <artifactId>spring-boot-starter-web</artifactId>

4. </dependency>

After the project starts successfully , Can be in eureka server View the registered instance information in the information panel of , as follows ：
