mybatis配置mapper-locations的坑

很多时候想把可扩展标记语言文件与制图人类放在一起。

　　地图绘制者-位置： com。演示。道。*。可扩展标记语言这么配置之后发现报错找不到可扩展标记语言中编号

　　pom.xml配置这句话就可以了!

　　构建资源资源目录RC/main/Java/目录包含包括**/* .XML/include/includes筛选true/filtering/resource/resources/build

mapperLocations配置失效

xml文件的目录结构：分神谕数据库的mapper.xml文件夹和瀚高数据库的mapper.xml文件夹

　　框架配置： 加载瀚高的可扩展标记语言文件

　　启动项目报错信息：

　　我配置加载的是highgo文件夹下的xml文件，但他却还是加载oracle文件夹下的xml文件。

问题根源

　　项目的配置文件里面mybatis和mybatis-plus都配置了，而mybatis-plus的配置信息优先级高于mybatis的配置，所以导致mybatis的配置无效。

解决

使用mybatis-plus的配置，移除mybatis的配置。

　　以上为个人经验，希望能给大家一个参考，也希望大家多多支持盛行IT。
