怎么利用idea快速搭建一个springcloud

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@EnableEurekaServerpublic 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: 8888eureka:  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/

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！

3、创建一个服务提供者（就是常写的spring-boot）

服务提供者配置，如下：

package com.example.provider; import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.eureka.EnableEurekaClient; @SpringBootApplication//声明为注册服务@EnableEurekaClientpublic class ProviderApplication {     public static void main(String[] args) {        SpringApplication.run(ProviderApplication.class, args);    } }

配置文件改用yml，配置如下：

eureka:  client:    serviceUrl:      #服务注册地址      defaultZone: http://localhost:8888/eureka/server:  #运行端口  port: 8001spring:  application:    #服务注册名称    name: service-provider

按照写springboot那样写一个查库接口

package com.example.provider; import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.eureka.EnableEurekaClient;import org.springframework.context.annotation.ComponentScan; @SpringBootApplication//声明为注册服务@EnableEurekaClient//扫描所有包@ComponentScan("com.test")//扫描mapper@MapperScan("com.test.mapper")public class ProviderApplication {     public static void main(String[] args) {        SpringApplication.run(ProviderApplication.class, args);    } }

yml配置

eureka:  client:    serviceUrl:      #服务注册地址      defaultZone: http://localhost:8888/eureka/server:  #运行端口  port: 8001spring:  application:    #服务注册名称    name: service-provider  #数据库链接  datasource:    username: root    password: yh996112    url: jdbc:mysql://localhost:3306/yanghao?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC    driver-class-name: com.mysql.cj.jdbc.Driver#mybatis配置mybatis:  mapper-locations: classpath:mapper/*Mapper.xml  type-aliases-package: com.test.doman

OK，查库然后接口返回数据成功！

咱们的服务也在注册中心中注册成功啦！

4、创建一个消费者服务

点击完成创建该模块

启动器配置

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//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）@EnableFeignClientspublic class ConsumerApplication {     public static void main(String[] args) {        SpringApplication.run(ConsumerApplication.class, args);    } }

配置文件改用yml，配置如下：

eureka:  client:    serviceUrl:      #服务注册地址      defaultZone: http://localhost:8888/eureka/server:  #运行端口  port: 8002spring:  application:    #服务注册名称    name: service-consumer

将服务提供者模块中的controller复制到消费者模块，如果涉及doman中文件就一并复制过去。

package com.example.consumer.service; import com.example.consumer.doman.Test;import org.springframework.cloud.openfeign.FeignClient;import org.springframework.stereotype.Service;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestParam; /** * @Description：使用@FeignClient注解调用注册子模块接口方法 * @Author :y *///注册子模块名称@FeignClient("service-provider")public interface TestService {    //接口访问地址    @GetMapping("index/index")    public Test getTest(@RequestParam("id") Integer id);}

接口调用该service
