这篇博客详细介绍了如何使用Spring Boot和Spring Cloud来搭建一个Eureka注册中心。通过配置pom.xml引入相关依赖，设置application.properties启动Eureka服务，并创建App.java应用启动类，以及HelloController用于测试。启动应用后，Eureka注册中心会在8761端口运行，可以通过浏览器访问http://localhost:8761进行验证。

</project>

application.properties配置

server.port=8761
spring.application.name=eureka
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

App.java

package com.sunyard;

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

@EnableEurekaServer
@SpringBootApplication
public class App {

    public static void main( String[] args ) {
        SpringApplication.run(App.class, args);
        System.out.println( "注册中心启动成功！" );
    }
}

这里注意加上这个注解@EnableEurekaServer

HelloController.java

package com.sunyard;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

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

@Value("${spring.application.name}")
private String name;

    @RequestMapping("/hello")
    public String hello(){
        return name+":"+port+"--"+"Welcome to start SpringBoot!";
    }
}

启动App.java文件，查看控制台输出日志，注册中心启动成功。端口：8761

浏览器输入http://localhost:8761
