Could not find resource com/meng/dao/UserMapper.xml

1、xml文件放在src路径下，无法识别。pom.xml添加：

<!--静态资源导出问题-->
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

或者映射路径，在核心配置文件xml中添加指向xml所在位置，注意斜杠不要写成点.  搞半天才发现的！！

<mappers>
        <mapper resource="com/meng/dao/UserMapper.xml"/>
