调试了一天的bug  发现心不在焉敲出的代码真是  粗我屋百出 ，最后我总结了几点 mybiets 中错误的几个主要点

1。

mybits 的 接口类

public interface SalePlanMapper {public List <SalePlan>   <strong><span style="color:#ff6666;">list</span></strong>  (int uid);//根据不同用户的id的角色查询出不同的销售列表的内容}

// 接口的方法名 应于 配置的文件名相同

//接口的返回类型应于配置文件的类型对应

//我的配置文件 结果集为 resultMap类型的，也主要是因为这个错的

//其他简单的错误 可能是因为  数据库中的字段和 配置文件或者 mybatis 的配置文件的字段不相同 导致的错误

2。mybaits 的配置文件
