Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 类似这种错

org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.xingxue.service.SeckillService com.xingxue.test.serviceImpl.SeckillServiceImplTest.seckillService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.xingxue.service.SeckillService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

类似这种错误,

首先,看下所有的配置文件是否正确。

 

第二:习惯性的包命名习惯:   com.xx.service

                                        com.xx.service.impl

 

有关扫描service包的配置:

Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 类似这种错

这种配置是正确的,但是有一个隐蔽的错误    就是service的实现类的包名写成:  com.xx.serviceImpl

那么无论如何,spring也无法扫描到你的service实现类,那么项目就会报错
