注册中心注册服务

一. 搭建一个Springboot项目

二. 导入eureka的jar包

<?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">
	<modelVersion>4.0.0</modelVersion>
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.3.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.mr</groupId>
	<artifactId>springboot-eureka</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<name>springboot-eureka</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.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
		</dependency>

		<dependency>

			<optional>true</optional>

		<dependency>

			<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>

三. 配置yml配置文件

server:
  port: 8081
spring:
  application:
    name: GetGoodList  # 注册中心内显示的名称--服务名称！
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8080/eureka/  # 路径与注册中心的端口号一致

四. 启动类添加注释@EnableEurekaClient

@SpringBootApplication
@EnableEurekaClient   //客户端使用，---》注册服务
public class SpringbootEurekaServiceApplication {

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

}

五. 写一个测试方法

@RestController
public class GoodController {


    /**
     * 查询商品集合数据 接口
     * @return
     */
    @RequestMapping("getGoodList")
    public List getGoodList(){
        List list = new ArrayList();
        list.add("iphonex");
        list.add("iphonexs max");
        list.add("iphonexr");
        return list;
    }
}

六. 查看显示下图，成功将服务注册到注册中心

1. 访问 127.0.0.1:8081/getGoodList

2. 最后访问 127.0.0.1:8080
