【jeecg-mybatis版本】 mybatis+spring mvc 完美整合方案 查询，保存，更新，删除自动生成

Jeecg-Mybatis版本代码生成器演示视频 

  http://pan.baidu.com/share/link?shareid=243717&uk=2668473880 
简要说明 
JEECG[J2EE Code Generation] 
代码生成：根据表生成对应的Bean,Service,Dao,Action,XML,JSP等,增删改查功能直接使用,实现了快速开发 
jeecg-mybatis-framework,采用SpringMVC+Mybatis等主流框架 
支持数据库: Mysql,Oracle10g 
前端:使用Jquery和Easyui技术.JS封装简洁,操作简单. 
权限:对菜单,按钮控制.根据登陆用户权限展示拥有的菜单和按钮. 
拦截:对所有无权限URL进行拦截,防止手动发送HTTP请求,确保系统全性.

还有，有些写法个人觉得可以更简练些、命名也可以更优雅些（有些看起来好像是直接用mybatis官方代码生成器，╮(╯▽╰)╭ ），比如SQL Wheres

<sql id="sqlWheres">
	<trim prefix="WHERE" prefixOverrides="AND |OR ">
		<if test="id!=null">AND supplier_id=#{id}</if>
		<if test="code!=null and code!=''">AND supplier_code LIKE #{code}</if>
	</trim>
</sql>

为什么不直接使用Mybatis的useGeneratedKeys和keyProperty，而另起炉灶用“<selectKey>”？
