报错定位：

    @Select(" Select * from seller_stuff_run ")    @Results(            value = {                    @Result(column = "stuff_id",property = "stuffs"）                    @Result(column = "seller_id",property = "sellers"）            }    )    List<SellerStuffRun> findAllSellerStuffRun();

错误原因：
没有有理解@One的含义。
One=@One(select = "com.qingyunqifu.dao.SellerDao.findSellerById",fetchType = FetchType.EAGER))

解决方案：

     //给两个@Result结果映射添加关联映射@One     //给两个@Result结果映射添加关联映射@One     //给两个@Result结果映射添加关联映射@One    @Select(" Select * from seller_stuff_run ")    @Results(            value = {                    @Result(column = "stuff_id",property = "stuffs",one = @One(select = "com.qingyunqifu.dao.StuffDao.findStuffById",fetchType = FetchType.EAGER)),                    @Result(column = "seller_id",property = "sellers",one = @One(select = "com.qingyunqifu.dao.SellerDao.findSellerById",fetchType = FetchType.EAGER))            }    )    List<SellerStuffRun> findAllSellerStuffRun();

总结：

@Result(column = "seller_id",property = "sellers",one = @One(select = "com.qingyunqifu.dao.SellerDao.findSellerById",fetchType = FetchType.EAGER))

这行代码的意思将 seller_id作为 SellerDao类的findSellerById参数进行查询，查询出的结果在赋值给property = sellers。注：sellers是一个class对象（我定义的类）。
