代码如下

String sql = "select t1.* from t_snow_call_mobile t1 LEFT JOIN   t_snow_borrow_application t2 on t1.id_borrow_application = t2.id where t2.id_credit_user=@idUser order by t1.craw_time desc limit 0,1";
		SqlTemplate sqlTemplate = new SqlTemplate(dao);
		Map params = Maps.newHashMap("idUser",idUser);
		CallMobile callMobile = sqlTemplate.queryForObject(sql, params,CallMobile.class);

我查询的明明是一个对象,但是,返回的时候只返回了一个id,结果报Long无法转换为CallMobile
异常如下:

  For example:> "select t1.* from t_snow_call_mobile t1 LEFT JOIN   t_snow_borrow_application t2 on t1.id_borrow_application = t2.id where t2.id_credit_user=71135 order by t1.craw_time desc limit 0,1"
