idea快速搭建一个spring-cloud

package com.example.consumer;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Component;
@SpringBootApplication
 
//扫描所有包
@ComponentScan("com.test")
//声明为注册服务
@EnableEurekaClient
//把调用注册子模块接口引入到Spring容器中（不加此注解会出现找不到@FeignClient修饰的接口）
@EnableFeignClients("com.test")//包路径解决启动类在别的包下问题
 
public class ConsumerApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class, args);
    }
 
}

1、创建一个空的maven项目！




2、创建一个注册中心模块




3、配置注册中心

package com.example.eurekaserver;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
 
@SpringBootApplication
//声明为注册中心
@EnableEurekaServer
public class EurekaServerApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }
 
}

配置文件改用yml，配置如下：

server:
  #运行端口
  port: 8888
eureka:
  instance:
    #注册ip
    hostname: localhost
  client:
    #禁止自己当做服务注册
    register-with-eureka: false
    #屏蔽注册信息
    fetch-registry: false
    #注册url
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

注意pom文件中springcloud与springboot的版本对应问题

启动成功后，访问本地+端口即可看到注册中心页面，说明成功啦！
