如果同学你遇到这个Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'com.imooc.o2o.dao.split.DynamicDataSourceInterceptor。则证明你这边用的是最终代码的配置，建议你没有相关解决问题的能力之前，请一步步按照视频配置来，因为最终配置里面是后面的内容，有配置加密以及主从库的配置等，这里由于还缺少后面的类所以报错。

同学好，麻烦把错误信息以文字的形式都贴出来哈，有部分遮住了，而且有可能贴出了之后也会不全，因为这个跟DI注入配置相关，配置信息我这边没办法看到呢。同学请对比下spring-dao.xml mybatis-config.xml 以及mapper的配置。感觉是没找到areaDao或者Area实体类

同学好 Could not resolve type alias 'com.imooc.o2o.dao.split.DynamicDataSourceInterceptor'. Cause: java.lang.ClassNotFoundException: Cannot find class: com.imooc.o2o.dao.split.DynamicDataSourceInterceptor 报了这个错误哈 把mybatis-config.xml里面的这个字段去掉就可以了
