测试dao也是这个错误

• 翔仔 #1

  得确保把配置正确 以及 output目录 test和 main发布到同一个目录，同学也可以加群，这样和大家一起解决问题更便捷 群里有大神

错误信息是areaDao没有创建

Answer 3

翔仔 2017-11-02 07:39:14

同学要学会看错误哈，只看自己认识的就可以，Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'areaServiceImpl': Unsatisfied dependency expressed through field 'areaDao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.imooc.o2o.dao.AreaDao' available: expected at least 1 bean which qualifies as autowire candidate. 主要是这个 看起来是service配错了

• 提问者 Che_ #1

  service就是跟着考试视频写的一样的，测试dao层的时候，报错说areaDao，有问题，

• 翔仔 #2

  因为同学具体怎么配置的 我这边也看不到 只能依据错误去做推测 请问同学扫描的package是不是到service层，同时mapper是否指定了areadao，大小写要区分哦 还有mybatisconfig的配置也要正确，我这几天都在海岛，估计问题解决的不太及时，同学可以在群里提问，他们也是按视频弄的结果都通过了，看看有没有人解决过这个问题：）
