一、Spring Cloud 起步

吐槽

Spring Cloud 版本之间的变化有些大呀！！坑死人了！！

Spring-Cloud 版本：Finchley.SR2

Spring-Boot 版本：2.0.9.RELEASE

 

目录：

1.搭建Eureka注册中心；

2.搭建服务提供者，并向注册中心注册自己；

3.搭建服务消费者，消费服务；

 

1 搭建Eureka注册中心

import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class DemoApplication {

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

}

 

　　application.yml

server:
  port: 1313
spring:
  application:
    name: ServerCenter
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

 

　　启动访问  http://localhost:1313/

 

2.搭建服务提供者，并向注册中心注册自己；

　　DemoApplication.java

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class DemoApplication {

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

}

　　application.yml

server:
  port: 8080
spring:
  application:
    name: SERVER-ONE
eureka:
  client:
    service-url:
      defaultZone: http://localhost:1313/eureka/

　　这时再次访问  http://localhost:1313/

　　可看到服务已经注册到了Eureka注册中心
