解决：Could not find resource org/example/mapper/Mapper.xml

错误提示信息;

Caused by: java.io.IOException: Could not find resource org/example/mapper/Mapper.xml
	at org.apache.ibatis.io.Resources.getResourceAsStream(Resources.java:114)

这个错误是找不到Mapper.xml文件

1、配置文件和类都没问题

2、这个是我用Idea的maven项目时出现的一个bug

3、在网上查询的时候发现Idea中的src/java文件不支持xml

解决办法：

在maven中pom.xm文件中添加

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