Unsatisfied dependency expressed through bean property 'dataSource'

用AbstractTransactionalDataSourceSpringContextTests（当时只想单纯的试下，没有配置dateSouce）
报的错：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name

'com.MM2': Unsatisfied dependency expressed through bean property 'dataSource': Set this property value

or disable dependency checking for this bean.


解决办法：在测试类的构造方法 setDependencyCheck(false);//不去检查


折腾了我半天啊
用AbstractDependencyInjectionSpringContextTests没有这些麻烦，但是他不能数据回滚
