@Results({
@Result(id=true,column="id",property="id"),
@Result(column="goodsId",property="goods",one=@One(select="com.softeem.dao.CategoryDao.findGoodsById",fetchType=FetchType.EAGER)),
@Result(column="userId",property="user",one=@One(select="com.softeem.dao.UserDao.selectUserById",fetchType=FetchType.EAGER)),
})
public List selectAllById(@Param("userId")int userId);
