用IDEA新建了一个测试MyBatis工程，工程目录如下

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3d0X2JldHRlcg_size_16_color_FFFFFF_t_70]  
其中config是MyBatis的配置文件，内容如下

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
        <environments default="development">
            <environment id="development">
                <transactionManager type="JDBC"></transactionManager>
                <dataSource type="POOLED">
                    <property name="driver" value="com.mysql.jdbc.Driver"/>
                    <property name="url" value="jdbc:mysql://localhost:3306/mybatis"/>
                    <property name="username" value="root"/>
                    <property name="password" value="19871111"/>
                </dataSource>
            </environment>
        </environments>
    
        <mappers>
            <mapper resource="com/shao/mapping/userMapper.xml"/>
        </mappers>
    </configuration>

编译时提示错误 Error parsing SQL Mapper Configuration. Cause: java.io.IOException: Could not find resource com/shao/mapping/userMapper.xml

即找不到userMapper.xml这个Mapper文件，仔细查看了目录设置，并没有错误，在网上找了半天，终于发现原因：

idea不会编译src的java目录的xml文件

所以解决思路就是：将IDEA maven项目中src源代码下的xml等资源文件编译进classes文件夹

具体操作方法就是：配置maven的pom文件配置，在节点下添加代码：
