2.启动类
package com.soft.registerServer;

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

@EnableEurekaServer
@SpringBootApplication
public class EurekaApplication {

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

}
