利用idea快速搭建一个spring-cloud(图文)

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
