    IDEA需要添加一下内容，否则无法找到mapper
-->
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/web/dal/*/mapper/*Mapper.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

如果在mybatis的xml配置无误情况下，还出现Invalid bound statement (not found) ，那么就在当前模块的pom.xml中添加此段代码。
