告别永无止境的CRUD, 从零开始写Java代码生成器(一)

最近总是不断的在增删改查,复制, 粘贴, 有什么办法能摆脱这种现状呢? 我知道你也一定很讨厌重复的工作, 庞大的管理系统让我们把复制粘贴运用到了极致,这样永无止境下去, 跟搬砖又有什么区别?

于是, 动手来写一个代码生成器吧! 从Javabean到Dao,Mapper,Service,Controller,JSP 都交给代码生成器来完成好不好?

新建一个Maven项目,CodeGenerator, 其pom.xml核心配置如下:

 1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

pom.xml 中加入了一些可能或者必须用到的jar包;

整体的项目结构大致如下:(目前版本0.1)
