最近想架构一个SSM的项目，注入的Service接口  项目启动却告知有两个相同的service 

配置文件：

包结构如下：

在service注解上加

@Service("test")

在@Autowired下加
@Qualifier("test")
可以实现按名字注入

单不是我想要的效果，我只想写个
@Autowired  实现接口的注入

求教！！！！

你那两个配置文件是不是扫描了两次啊？

收获园豆：20
让我发会呆 | 老鸟四级 |园豆：2929 | 2017-01-04 15:29

扫描一个和扫两次区别不大   第一次扫描  我是准备只扫描controller的  已经修改了

LewsKay | 园豆：186 (初学一级) | 2017-01-04 15:31

@LewsKay: ？  第一张图片里的扫描就够了，把画红线的干掉，试试

让我发会呆 | 园豆：2929 (老鸟四级) | 2017-01-04 15:37

@让我发会呆: 还是不行

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [com.myjava.demo.web.test.service.IService] is defined: expected single matching bean but found 2: serviceImpl,IService

想让它自动装配进去的， 之前用的项目跟我自己配的也没差啊   怎么就不行呢  @Autowired  注入接口就失败 ，注入实现类就成功  或者在@Service注解上加上唯一name   在controller 的在@Autowired下加@Qualifier("name")  也能成功，就直接用接口不成功

LewsKay | 园豆：186 (初学一级) | 2017-01-04 15:42

@LewsKay: @Resource试试吧
