SpringCloud微服务实战：一、Eureka注册中心服务端

1.项目启动类application.java类名上增加@enableeurekaserver注解，声明是注册中心

 1 import org.springframework.boot.springapplication;
 2 import org.springframework.boot.autoconfigure.springbootapplication;
 3 import org.springframework.cloud.netflix.eureka.server.enableeurekaserver;
 4 @springbootapplication
 5 @enableeurekaserver
 6 public class eurekaapplication {
 7  public static void main(string[] args) {
 8  springapplication.run(eurekaapplication.class, args);
 9  }
10 }

2.application.yml配置：

 1 #配置注册中心服务端信息
 2  eureka:
 3  client:
 4  service-url:
 5  defaultzone: http://localhost:8762/eureka/
 6  #配置是否显示在注册中心上
 7  register-with-eureka: false
 8  #自我保护机制,开发环境可以关闭，生产环境必须开启
 9  server:
10  enable-self-preservation: false
11  #配置在注册中心显示的名字
12  spring:
13  application:
14  name: eureka
15  #配置服务端口
16  #server:
17  #  port: 8761

3.pom.xml配置:

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"

4.打包：mvn clean install -dmaven.test.skip=true
5.启动注册中心服务端：java -jar eureka-0.0.1-snapshot.jar
