关于XML fragments parsed from previous mappers already contains value for

在使用MyBatis进行项目开发时,遇到XML片段解析错误'XML fragments parsed from previous mappers already contains value for'。通过排查发现是SQL映射中的parameterType或resultType书写错误导致类型不存在的问题。本文分享了解决过程和解决方案。

最近有myibatis做项目的时候发现报了这个错误XML fragments parsed from previous mappers already contains value for,百度和谷歌很久都没找到具体的原因,排查了一天,发现是sql映射到XML的parameterType或者resultType写的有问题,所以导致类型不存在,惭愧
