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。

[code] 


<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; 

 }
