逆向工程文件example完美结合使用PageHelper分页插件及分页不成功原因

原生的mybatis需要手写sql语句，项目数据库表多了之后，可以让你写sql语句写到手软，于是mybatis官方提供了mybatis-generator：mybatis逆向工程代码生成工具，用于简化mybatis单表操作。

在PageHelper3.几的版本的时候，使用它对逆向工程生成的查询方法进行分页时出现失效的情况，而PageHelper4开始，亲测能够与mybatis逆向工程生成的方法完美兼容，今天就和大家分享spring+springmvc+mybatis+PageHelper的项目遇到的问题(今天就被使用3.几的版本失效而折磨，还以为sql语句写错了，最后还是被发现了，完美)
