1. 首先將所有

   開始於
   <dependencies>
   結束於
   </dependencies>中的檔案放到最外層的專案中，裡面的方法就不需要寫version了

2. 
3. 需要在2中的pom.xml檔案中新增一層

4. <dependencyManagement>
   <dependencies>...</dependencies>
   </dependencyManagement>

5. 可以將所有版本號資訊就行抽離

6.     <properties>
           <project.build.soureEncoding>UTF-8</project.build.soureEncoding>
           <project.compile.soureEncoding>UTF-8</project.compile.soureEncoding>
           <sharedingsphere.version>4.1.0</sharedingsphere.version>
           <springboot.versinon>2.2.5.RELEASE</springboot.versinon>
       </properties>

               </dependency>
           </dependencies>
       </dependencyManagement>
    
   

   version中版本資訊為上面properties中配置的資訊，起到方便管理的作用
