关于 MyBatis配置的时候，出现 Result Maps collection already contains value for *** 这个的问题 字面意思就是某某已经存在，这样的情况下
3.可能的原因 （1）namespace 已经存在 （2）id 已经存在 二、参考资料 1.Mybatis启动报Result Maps collection already contains value...for ...的问题 1.mybatis(错误一) 项目启动时报“Result Maps collection already contains value forxxx”的解决方案 2.Mybatis...异常-Result Maps collection already contains value for xxx 3.mybatis报错“Result Maps collection already contains...value for ***” 4.
昨天用eclipse启动springmvc+mybatis的项目,报错了,信息如下: Result Maps collection already contains value for xyx.dsw.dao.mapper.admin.quotationwish.TempTestTableMapper.TempTestTableResult...Cause: java.lang.IllegalArgumentException: Result Maps collection already contains value for xyx.dsw.dao.mapper.admin.quotationwish.TempTestTableMapper.TempTestTableResult...Maps collection already contains value for xyx.dsw.dao.mapper.admin.quotationwish.TempTestTableMapper.TempTestTableResult...Cause: java.lang.IllegalArgumentException: Result Maps collection already contains value for xyx.dsw.dao.mapper.admin.quotationwish.TempTestTableMapper.TempTestTableResult...这样就会出现 java.lang.IllegalArgumentException: Result Maps collection already contains value for XXX这个错误。

我这个异常是因为当时拷贝的时候没仔细看导致的 改成 resultType 就可以了。 resultMap 和 resultType 的事例：
XML fragments parsed from previous mappers already contains value for xxx 此次碰到mybatis这个报错, 是因为在两个不同的...其实从报错的提示上也基本上可以看出来是赋值问题:already contains value for xxx.
