报错原因是因为我在mybatis里面这段代码没有删除导致spring和mybatis都扫描了一遍xml，就出错了。

　　<mappers>
        <mapper resource="cn/dao/WorkinggMapper.xml"/>
    </mappers>

这两段代码只要删一段就行，删spring里面的或者mybatis的都行

    <!-- 配置SQL映射文件信息 -->
        <property name="mapperLocations">
            <list>
                <value>classpath:cn/dao/**/*.xml</value>
            </list>
        </property>
