Oracle+ibatis的<select>中resultClass是java.util.HashMap 返回结果key都是大写的变量名 如何解决

如题:
Oracle+ibatis的中resultClass是java.util.HashMap 返回结果key都是大写的变量名 如何解决

如果用resultClass用自定义的class可以解决,那么不同的多表查询岂不是要定义多个class来装这些结果集,即便是用resultMap还是得定义相关的配置,总不会每定义一个(假设都是多表查询,而且都是不同的表),都要定义一个resultClass或者resultMap吧?
我现在的问题是:用ibatis中的返回一个结果集List>,我希望Map中的key与我sql中的字段大小写一致,但是我又不想针对每个都定义一个resultClass或者resultMap,但是我如果用HashMap作为resultClass,Map中的key都是大写。PS:数据库是ORACLE,这个数据库有关,但是项目就是用的这个,没得办法改他,谢谢

每次都一定bean不烦吗,保存的时候用bean我不反对,但是返回的时候返回一个对象不一定合适,而且保存大部分情况都是针对但表,查询针对多表的情况比较多,

总是多表查询的话,如果表大部分情况不是一样的话,定义bean不麻烦吗,用HashMap就没这样的事,但是map的key总是大写,不能像自定义bean一样大小写可以和sql中的column一样

[/quote]
我们都是用bean,架构师禁止用HashMap。
定义bean是麻烦一些,尤其每次多表查询的时候,不过定义了一个专门返回查询结果的bean,一般的多表查询就返回这个bean。
当然具体业务不一样,也许一个这样的bean满足不了你的需要,也可多定义几个这样的bean.

供参考~

建议直接用resultClass,返回domain对象,不要用resultMap.

我觉得楼主不用resultClass 是怕定义bean麻烦

[quote]我觉得楼主不用resultClass 是怕定义bean麻烦[/quote]
面向对象嘛,用返回对象是比较好的选择。~

应该是没办法改吧,用大写的吧,我一直都这样用

[quote]大写返回到页面就不能复制了,要TM的一个字一个字的打,而且也看的不爽 [/quote]

在以前的公司也是一直用HashMap,也是得写成大写的。
不过没LZ这么反感~ 也许是那时习惯了

呵呵!页面迭代的时候时我都是手工输入的(貌似还好,字段名而已,用多了习惯就好了),感觉不爽的话你定义返回bean的映射。

你看拿到值后能不能转成小写

ibatis中动态查询表返回用resultClass="java.util.HashMap" 的问题

用spring+ibatis写了一个登陆页面输入表名 然后在页面查询出表的数据, sql配置文件 </select> <select id="getTableDataByPage" resultClass="java.util.HashMap" parameterClass="java.util.HashMap"> <![CDATA[ select * from (select rownum id,t.* from $tableName$ t where rownum<= #endNum# ) b where b.id>= #startNum# ]]> </select> 第一次运行服务器输入一个表名可以查询出表的所有信息,退出返回到登陆页面重新输入一个表名查询就会出错 日志显示: Cause: java.sql.SQLException: 列名无效 com.ibatis.common.jdbc.exception.NestedSQLException: --- The error occurred in com/zf/querytest/bo/impl/tableDao.xml. --- The error occurred while applying a result map. --- Check the tableDao.getTableDataByPage-AutoResultMap. --- Check the result mapping for the 'TASKID' property. 其中TASKID为上一张表中的字段,也就是ResultMap中保留了上个表的字段信息,将sqlMapClient中的cacheModelsEnabled设置为"false"也不行 请问我要怎样修改才能在重新输入表名后查询后返回新的表的结果了,请大家帮帮忙,谢谢 [b]问题补充:[/b] 感谢lggege的关注,目前只能重新启动才能重新查询另一张表的数据

iBATIS 將model 中的java.util.date類型做insert時候提示無效列類型問題

model 的某一個字段A在為java.util.Date,對應table中的data類型 可為空 但是在做inert動作的時候,如果model中的A=null,插入就會出現無效的列類型的提示,為什麼。。。。

mybatis 查询返回java.util.HashMap 类型的数据

Map<String, Object> Object 可以是List[String] 例: { "name":"", "pwd":"", "log":["","",""] }

昨天早上通过远程的方式 review 了两名新来同事的代码,大部分代码都写得很漂亮,严谨的同时注释也很到位,这令我非常满意。但当我看到他们当中有一个人写的 switch 语句时,还是忍不住破口大骂:“我擦,小王,你丫写的 switch 语句也太老土了吧!” 来看看小王写的代码吧,看完不要骂我装逼啊。 private static String createPlayer(PlayerTypes p...

副业收入是我做程序媛的3倍,工作外的B面人生是怎样的?

提到“程序员”,多数人脑海里首先想到的大约是:为人木讷、薪水超高、工作枯燥…… 然而,当离开工作岗位,撕去层层标签,脱下“程序员”这身外套,有的人生动又有趣,马上展现出了完全不同的A/B面人生! 不论是简单的爱好,还是正经的副业,他们都干得同样出色。偶尔,还能和程序员的特质结合,产生奇妙的“化学反应”。 @Charlotte:平日素颜示人,周末美妆博主 大家都以为程序媛也个个不修边幅,但我们也许...

【高并发】高并发秒杀系统架构解密,不是所有的秒杀都是秒杀!

网上很多的文章和帖子中在介绍秒杀系统时,说是在下单时使用异步削峰来进行一些限流操作,那都是在扯淡! 因为下单操作在整个秒杀系统的流程中属于比较靠后的操作了,限流操作一定要前置处理,在秒杀业务后面的流程中做限流操作是没啥卵用的。

代码注释如此沙雕,会玩还是你们程序员!

某站后端代码被“开源”,同时刷遍全网的,还有代码里的那些神注释。 我们这才知道,原来程序员个个都是段子手;这么多年来,我们也走过了他们的无数套路… 首先,产品经理,是永远永远吐槽不完的!网友的评论也非常扎心,说看这些代码就像在阅读程序员的日记,每一页都写满了对产品经理的恨。 然后,也要发出直击灵魂的质问:你是尊贵的付费大会员吗? 这不禁让人想起之前某音乐app的穷逼Vip,果然,穷逼在哪里都是...
