springCloud系列第二篇-Eureka客户端

接上一篇。代码结构如下图

代码结构

1、pom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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>

        <groupId>com.cloud</groupId>
        <artifactId>cloud-parent</artifactId>
        <version>1.0-SNAPSHOT</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.cloud</groupId>
    <artifactId>service-hi</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>service-hi</name>

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


</project>

2、配置文件

server.port=8762
spring.application.name=service-hi
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

3、启动类

package com.cloud.service.hi;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@EnableEurekaClient 
@SpringBootApplication
public class ServiceHiApplication {

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

}

4、随便写一个controller测试

package com.cloud.service.hi.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author: zhouwei
 * @version: v1.0
 * @description: com.cloud.service.hi.controller
 * @date:2021-01-25
 */
@RestController
public class UserController {
    @GetMapping("/user/{id}")
    public String getUser(@PathVariable long id){
        System.out.println(id);
        return "我是谁啊";
    }
}
