文章讲述了在Java开发中遇到的一个错误，即在Mapper配置中ResultMap的ID重复导致的IllegalArgumentException。提出了两种解决方案：一是对于数据结构相同的ResultMap使用@ResultMap注解复用；二是如果数据结构不同，只需确保ID唯一即可避免冲突。

异常信息

 

2023-07-05 23:13:53.791 ERROR 80094 --- [           main] o.m.spring.mapper.MapperFactoryBean      : Error while adding the mapper 'interface com.tencent.gateway.mapper.AcceptBusiMapper' to configuration.

java.lang.IllegalArgumentException: Result Maps collection already contains value for com.tencent.gateway.mapper.AcceptBusiMapper.acceptBusi

是因为mapper代码里 Results.id 的名字重复了：

方式一：数据结构相同的情况下，使用 @ResultMap 注解复用映射对象

@ResultMap(value= "acceptBusi")

方式二：数据结构不同的情况下，修改重名ID，只要不重复就好

使用 Mybatis 时报 java.lang.IllegalArgumentException: Result Maps collection already contains… 异常，目前碰到的原因如下： *.xml 中 id 存在重复，分两种情况 - 写的时候粗心写重复，此时你就重新起个 id 名吧 - 逆向工程中 mybatis 用什么追加模式，导致编译后的文件中存在重复，此时就 clean 一下，然后重新 compile。说白了就是删除文件，重新编译。 *.xml 中 类型写错，例如 resu
