介绍
Spring Cloud 是一个基于 Spring Boot 实现的云应用开发工具，它为开发中的配置管理、服务发现、断路器、智能路由、微代理、控制总线、全局锁、决策竞选、分布式会话和集群状态管理等操作提供了一种简单的开发方式。
springcloud 常用组件
1.创建父工程
创建后目录
2.删除父工程的src目录
3.修改父工程的pom文件

注意画圈 处更改
4 springcloud 版本依赖
在导入依赖版本时 尽可能参考版本，负责很可能出现依赖错误 导致无法启动
官方依赖说明

|---|---|---|
| 2.2.10-RC1* | Spring Cloud Hoxton.SR12 | 2.3.12.RELEASE |
| 2.2.9.RELEASE | Spring Cloud Hoxton.SR12 | 2.3.12.RELEASE |
| 2.2.8.RELEASE | Spring Cloud Hoxton.SR12 | 2.3.12.RELEASE |
| 2.2.7.RELEASE | Spring Cloud Hoxton.SR12 | 2.3.12.RELEASE |
| 2.2.6.RELEASE | Spring Cloud Hoxton.SR9 | 2.3.2.RELEASE |
| 2.2.1.RELEASE | Spring Cloud Hoxton.SR3 | 2.2.5.RELEASE |

5.创建子模块
父工程->右击->new->module
选择maven创建，注意图片画圈位置
修改子项目的pom 文件，注意引入 <parent> 模块
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><!--注意此处--><parent><artifactId>springcloud_demo</artifactId><groupId>org.example</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>cloud_provider</artifactId><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties>
<!--只引入了web 依赖 根据需求自己引入--><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency></dependencies>
</project>
查看父工程依赖 idae 自动添加了 modules 标签
6 子项目下创建启动类
启动项目即可
@SpringBootApplication
public class ProviderApplication {public static void main(String[] args) {SpringApplication.run(ProviderApplication.class, args);}
}
