mybatis xml映射文件找不到

问题：
mybatis的xml映射文件找不到。
原因：
mapper.xml文件在java目录

       <resources>
            <resource>
                <!--此处配置到java是因为mapper.xml文件在java目录-->
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*</include>
                </includes>
            </resource>
        </resources>
