同学好，

这里的错误是

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.o2o.dao.AreaDao' available: expected at least 1 bean which qualifies as autowire candidate.

说的是同学的AreaDao没有找到对应的实现类，需要同学首先查看三个地方

1. 确保你的测试类继承自BaseTest.java，并且BaseTest.java已读入spring-dao.xml

2. spring-dao.xml的package扫描正确

3. area mapper xml文件里面指定是AreaDao接口的实现类
