Mybatis映射对应mapper文件路径错误问题

Mybatis映射对应mapper文件路径错误问题：SAXParseException; lineNumber: 1; columnNumber: 1; 前言中不允许有内容，BuilderException: Error creating document instance，NestedIOException: Failed to parse mapping resource: 'URL'，BeanCreationException: Error creating bean with name 'sqlSessionFactory'，Failed to load ApplicationContext

在Mybatis中需要mapper映射到具体文件中，来写与数据库进行交互的SQL；但前段时间发现在映射java.lang.IllegalStateException: Failed to load ApplicationContext org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [applicationContext.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [applicationContext.

`找了好长时间才发现问题，过程就不说了，直接说结论吧：`

`java文件夹下生成了对应项目的包以及文件，导致自己设置的<mapper resource="com/..."/>路径找不到对应的文件，`

`所以应该根据生成的路径去设置，在项目包路径前加上<mapper resource="java/com/..."/>就可以了！`

`以下为完整的报错信息：`
