springcloud工程建立 父工程+公用子模块+微服务提供模块

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

• 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：

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 -->
