代码拆分

项目原结构如下图：

 

 

拆分后结构如图：

 

 

在idea中打开项目，

选中项目右键选择

 

 创建两个maven项目，起名model-code，model-web。

把原项目的entity,mapper,vo,resources下面的myBatis的文件放到model-code项目下，结构如图：

 

 

原来项目剩下的文件都可以放到model-web项目下。

 

 

修改model-code项目的pom.xml文件

</project>

启动项目，就可以正常访问。

 

 

 

 

 

 

项目启动的时候会自动，把model-code项目打包，更新code项目的实体，重新启动也会生效。

上面两个如果不生效应该就是拆分不规范。
