SpringCloud核心教程 | 第二篇： 使用Intellij中的maven来快速构建Spring Cloud工程
spring cloud简介
spring cloud 为开发人员提供了快速构建分布式系统的一些工具，包括配置管理、服务发现、断路器、路由、微代理、事件总线、全局锁、决策竞选、分布式会话等等。它运行环境简单，可以在开发人员的电脑上跑。另外说明spring cloud是基于springboot的，所以需要开发中对springboot有一定的了解，如果不了解的话可以看这篇文章：2小时学会springboot。另外对于“微服务架构” 不了解的话，可以通过搜索引擎搜索“微服务架构”了解下。
在之前的所有Spring Boot相关博文中，都会涉及Spring Boot工程的创建。而创建的方式多种多样，这里，我们可以通过Maven来手工构建或是通过脚手架等方式快速搭建。
本文我们将介绍嵌入的Intellij中的maven工具，来快速的构建出一个基础的Spring Cloud工程。
创建工程
第一步： 菜单栏中选择File=>New=>Project..，我们可以看到如下图所示的创建功能窗口。然后，我们选择maven。
第二步： 点击Next，等待片刻后，我们可以看到如下图所示的工程信息窗口，在这里我们可以编辑我们想要创建的工程信息。其中，GroupId是工程的分组id，ArtifactId是模块分组id，Version是当前的版本。GroupId、ArtifactId、Version组合在一起形成一个模块的坐标
第三步： 点击Next，进入最后关于工程物理存储的一些细节。最后，点击Finish就能完成工程的构建了。
工程构建完成
加入pom坐标

创建日志配置文件
在工程resources文件夹下新建文件夹log，并在该文件夹下创建logback.xml文件,加入以下配置：

创建Controller
在工程java代码目录下创建controller的目录在下面创建DcController类用来测试服务是否已经注册到eureka并加入以下代码:
@RestController
public class DcController {
@Autowired
DiscoveryClient discoveryClient;
@GetMapping("/dc")
public String dc() {
String services = "Services: " + discoveryClient.getServices();
System.out.println(services);
return services;
}
}
创建启动类
@EnableDiscoveryClient //使用该注解将注册服务到eureka
@SpringBootApplication
public class SpringCloudDemoApplication {
public static void main(String[] args) {
new SpringApplicationBuilder(
SpringCloudDemoApplication.class).web(true).run(args);
}
}
控制台打印

eureka管控台正常显示
浏览器输入地址：
http://eureka.didispace.com/
看到服务已经成功注册。
当然，我们也可以通过直接访问eureka-client服务提供的/dc接口来获取当前的服务清单，只需要访问：http://localhost:2001/dc，我们可以得到如下输出返回：
Services: [zcs-apps-gateway, mystore-user-jwt, eureka-feign-client, scca-server-all-in-one, oms-system, zcs-apps-config, apollo-adminservice, staryun-product, tm-web, gateway-server, config-server, apollo-configservice, base-service, hd-cloud-boss, wm-svr-gateway, tm-admin, gzepro-manage-service, cva, zcs-jzsy-ops-new, x-cbiz, hd-config-server, wm-app-basicmanager, cloud-demo, wm-app-authserver, service-configuration, api-gateway]
可以看到cloud-demo包含在里面。至此maven快速构建cloud项目并启动测试已全部完成。
