定位：

     Could not find result map com.smbms.pojo.UserMapper.userlists

解决：对Spring配置文件的SQL映射文件扫描设置进行修改：
因为先前已经把映射文件的扫描返回扩大了，因此，会导致别的不相关的mapper文件也进行编译处理，导致出错。

把扫描范围缩小：

<!-- 配置SQL映射文件信息 ，逐个列出SQL映射文件麻烦，所以使用 mapperLocations 属性扫描加载SQL映射文件-->
    <property name="mapperLocations">
    <list>
    <value>classpath:com/smbms/dao/**/*.xml</value>
    </list>
    </property>
