Mybatis项目错误：Type interface dao.UserMapper is not known to the MapperRegistry.

检查mybatis-config.xml文件，将

<mappers><package name="mappers/UserMapper.xml"/>
</mappers>

改为

<mappers><mapper resource="mappers/UserMapper.xml"/>
</mappers>

二者区别：
接口文件与映射文件不在同一路径下,仅能用resource加载映射文件；
package加载方式仅适用于接口文件与映射文件在同一路径下,且接口名与映射文件名相同,并且映射文件命名为接口全类名的情况。

除此外，还有一种class加载方式，与package加载方式相似。

<mappers><mapper class="dao.UserMapper"/>
</mappers>
