java实体类生成工具

# 前言 #

原因是这样的，eclipse有那种生成实体类的插件，可是我感觉装来装去很麻烦，于是我想，干脆自己做一个生成实体类的工具吧，说做就做，然后就自己花了两个小时左右做出来了一个，以后应该能大大提高工作效率吧。

# 实现方法 #

输入：属性个数  
输入：type virableName  
输出：d盘下面的example文件，该文件里面生成了实体类的代码

原理就是填充数据而已。。。根本没有难度  
然后用了**map**模板把数据存起来了

# 使用截图 #

![这里写图片描述][SouthEast]  
\*\*这个是数据截图，CKCommand表示类，5表示有几个属性，剩下的都是数据属性  
然后把这个数据复制进控制台运行就可以了\*\*

**注意去D盘下面找**
