springcloud工程建立 父工程+公用子模块+微服务提供模块

1. 建立 Java Working Set：工程多的时候可以展开收缩，方便管理
   

   切换到Package Explorer视图，并点击视图右侧下箭头，选择Working Sets，如下图：
   

2. 建立父工程，将后续子工程公共的Jar包提出来：
   • 选择Working Set，右键New -> Maven Project：
     

   • 选择 Create a simple project，点击下一步
     

   • 创建父工程，父工程名称：thrcloud，Packaging：选择pom
     

   • 父工程建立完成，修改pom.xml文件：
     

     pom.xml文件内容如下，springcloud和springboot的版本可以选择比较新的版本对应关系，我这里比较旧：

             </dependencies>
         </dependencyManagement>
     
     </project>

3. 建立公共子模块 thrcloud-api：

   • 鼠标右键 thrcloud -> New -> Other
     
     
   • 选择 Maven Module
     

     

     

   • 创建了如下子模块工程 thrcloud-api，同时 thrcloud父工程的pom.xml文件也有所变化：
     
   • 修改 thrcloud-api工程的pom.xml文件，pom.xml内容如下：
     

     <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">
       <modelVersion>4.0.0</modelVersion>
     
       <parent>    <!-- 子类里面显示申明才能有明确的继承表现，无意外就是父类的默认版本，否则自己定义 -->
         <groupId>com.thr.springcloud</groupId>
         <artifactId>thrcloud</artifactId>
         <version>0.0.1-SNAPSHOT</version>
       </parent>
     
       <artifactId>thrcloud-api</artifactId>    <!-- 当前Module我自己叫什么名字 -->
     
       <dependencies><!-- 当前Module需要用到的jar包，按自己需求添加，如果父类已经包含了，可以不用写版本号 -->
               <!-- 用作自动隐式生成Entity的构造函数、get set方法、链式访问风格 -->
             <dependency>
                 <groupId>org.projectlombok</groupId>
                 <artifactId>lombok</artifactId>
             </dependency>
         </dependencies>
     </project>

4. 建立服务提供者模块 thrcloud-provider-user-8001 用户为服务提供者 Module
   • 选中 thrcloud 右键 -> New -> Maven Module ，如下图：
     
   • thrcloud-provider-user-8001工程如下图：

   • 修改 pom.xml文件，内容如下：

     <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">
         <modelVersion>4.0.0</modelVersion>

         </parent>
     
         <artifactId>thrcloud-provider-user-8001</artifactId>
     
         <dependencies>
             <dependency><!-- 引入自己定义的api通用包，可以使用Dept部门Entity -->
                 <groupId>com.thr.springcloud</groupId>
                 <artifactId>thrcloud-api</artifactId>
                 <version>${project.version}</version>

         </dependencies>
     
     </project>

   • 手动建立主启动类 UserProvider8001_App.java，如下图：
     
     到此完成！
