1.一对多用户和账户 @Select("select * from user") @Results(id = "resultMap",value = { @Result(id = true,property = "userId",column ="id"), @Result(property = "userName",column ="username"), @Result(property = "userSex",column ="sex"), @Result(property = "userAddress",column ="address"), @Result(property = "accounts",column ="id",many=@Many(select = "com.itheima.dao.IAccountDao.getAccountById", fetchType = FetchType.LAZY)), }) List<User> findAll(); 2.多对多 是由多个一对多组成，但是会产生中间表，上面的步骤相同，查询需要用到内连接 @Select("SELECT * FROM role WHERE id IN(SELECT rid FROM user_role WHERE uid=#{id}) ") Role getRoleById(Integer id)
