ibaits知识点

ibaits知识点:如果你要在DaoImpl里面得到一个List的话，我们只要在配置文件里面配置一下resultClass为Long或者是String。

<select id="selectRoleList" parameterClass="User" resultClass="Long">
	select roleid from t_str where stid=(select id from t_student where cardid=#cardId#)
</select>


@SneakyThrows
	@SuppressWarnings( { "unchecked" })
	@Override
	public Boolean add(User user) {
		insert("insertUser", user);
		Mediator mediator = null;
		List<Long> list = queryForList("selectRoleList", user);
		for (int i = 0; i < list.size(); i++) {
			mediator = new Mediator();
			Long pId = list.get(i);
			mediator.setOneId(user.getId());
			mediator.setOtherId(pId);
			insert("addRUMediator", mediator);
		}
		return true;
	}

List<Long> list = queryForList("selectRoleList", user);
