Spring mvc @ComponentScan在Spring3.2中是如何工作的?

Spring mvc @ComponentScan在Spring3.2中是如何工作的?,spring-mvc,annotations,autowired,Spring Mvc,Annotations,Autowired,我认为@ComponentScan能够以这种方式处理多个包: @ComponentScan(basePackages = { "com.foo.bar.service", "com.foo.bar.repository" }) 但是,每当我在包数组中添加多个包时,我都会得到一个异常,当我只使用com.foo.bar时也是如此(我认为当使用com.foo.bar时,com.foo.bar以及所有子包都会被扫描) 我如何告诉Spring扫描所有提到的包或包及其子包 例外情况: org.spring

我认为
@ComponentScan
能够以这种方式处理多个包:

@ComponentScan(basePackages = { "com.foo.bar.service", "com.foo.bar.repository" })
但是,每当我在包数组中添加多个包时,我都会得到一个异常,当我只使用
com.foo.bar
时也是如此(我认为当使用
com.foo.bar
时,
com.foo.bar
以及所有子包都会被扫描)

我如何告诉Spring扫描所有提到的包或包及其子包

例外情况:

org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'loginLogoutController': 
Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: 
Could not autowire field: private com.foo.bar.service.MyService com.foo.bar.controller.LoginLogoutController.myService; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'repositoryMyService': 
Injection of autowired dependencies failed; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Could not autowire field: private com.foo.bar.repository.MyRepository com.foo.bar.service.RepositoryMyService.myRepository; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type [com.foo.bar.repository.MyRepository] 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)}
repository类只是一个扩展
JpaRepository
的接口。
MyService
像往常一样是一个接口,
RepositoryMyService
实现
MyService
,并用
@Service
注释。
LoginLogoutController
带有
@Controller

注释,您应该能够执行您所说的操作(只需指定父包)。你能展示更多包含
@ComponentScan
注释的类吗?你启用了JPA存储库配置了吗?这就是我在此期间所做的工作:@EnableJpaRepositories
