报错信息

org.apache.ibatis.exceptions.PersistenceException:
Error building SqlSession.
The error may exist in mapper/xml/UsersMapper.xml
Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.io.IOException: Could not find resource mapper/xml/UsersMapper.xml

报错原因：在idea中不能编译src/main/java包下是xml文件
解决办法：在pom文件中进行配置使idea可以进行编译src/main/java包下的xml文件

在pom文件中配置

 <build>
 	<!-- 配置idea可以编辑src/main/java下的xml文件 -->
	  <resources>
	      <resource>
	          <directory>src/main/java</directory>
	          <includes>
	              <include>*/**/*.xml</include>
	          </includes>
	          <filtering>true</filtering>
	      </resource>
	  </resources>
</build>

问题解决，运行成功
