eureka 创建注册服务提供方

1. 创建eureka-client子项目

2. 添加pom依赖

<?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>
        <artifactId>spring-cloud-demo</artifactId>
        <groupId>com.imooc</groupId>
        <version>1.0.0-SNAPSHOT</version>
        <relativePath>../../pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <packaging>jar</packaging>
    <artifactId>eureka-client</artifactId>
    <name>eureka-client</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-web</artifactId>
        </dependency>
    </dependencies>
</project>

3. 创建启动类和服务内容

3.1 application.properties配置

spring.application.name=eureka-client
server.port=30000
eureka.client.serviceUrl.defaultZone=http://localhost:20000/eureka/

3.2 创建启动类

package com.imooc.springcloud;

import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaClientApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(EurekaClientApplication.class)
                .web(WebApplicationType.SERVLET)
                .run(args);
    }
}

3.3 创建服务内容
Controller

package com.imooc.springcloud;

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import static jdk.nashorn.internal.runtime.regexp.joni.Config.log;

@RestController
@Slf4j
public class Controller {

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

    @GetMapping("/sayHi")
    public String sayHi(){
        return "This is " + port;
    }

    @PostMapping("/sayHi")
    public Friend sayHiPost(@RequestBody Friend friend){
        log.info("You are " + friend.getName());
        friend.setPort(port);
        return friend;
    }
}

Friend

package com.imooc.springcloud;

import lombok.Data;

@Data
public class Friend {

    private String name;

    private String port;
}

4. 看下注册中心
