本文是接着上篇继续https://blog.csdn.net/qq_42014192/article/details/89188444

1.创建一个服务提供者 (eureka client)

2.修改pop.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->

    <name>springcloud_eureka-client_demo</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>Greenwich.SR1</spring-cloud.version>
    </properties>

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

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

3.通过注解@EnableEurekaClient 表明自己是一个eurekaclient

@SpringBootApplication
//通过注解@EnableEurekaClient 表明自己是一个eurekaclient
@EnableEurekaClient
@RestController
public class SpringcloudEurekaClientDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringcloudEurekaClientDemoApplication.class, args);
    }

    @Value("${server.port}")
    String port;

    @RequestMapping("/client")
    public String home(@RequestParam(value = "name", defaultValue = "forezp") String name) {
        return "client " + name + " ,i am from port:" + port;
    }
}

4.application.yml配置文件如下

server:
  port: 8762 #服务端口

spring:
  application:
    name: service-client

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

5.启动注册中心和服务提供者

启动工程，打开http://localhost:8761 ，即eureka server 的网址：

这时打开 http://localhost:8762/client?name=forezp ，你会在浏览器上看到 :
