错误提示为：

### Error building SqlSession.
### The error may exist in cn/qd/mybatis/map/productMapper.xml
### Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.io.IOException: Could not find resource cn/qd/mybatis/map/productMapper.xml

问题：在全局配置文件Configure.xml

<mappers>
    <mapper resource="cn/qd/mybatis/map/productMapper.xml"/>
</mappers>

无法找到资源的路径，在idea中貌似无法识别productMapper.xml

问题解决：既然找不到.xml文件，那么就在maven编译时将.xml文件放进去。即：在pom.xml文件的<build>标签中，加入

<resources>
  <resource>
    <directory>src/main/java</directory>
    <includes>
      <include>**/*.xml</include>
    </includes>
    <filtering>true</filtering>
  </resource>
</resources>
