在Spring MVC中自动装配MongoRepository

Question

我想将MongoRepository自动装入我的服务类,但我无法做到这一点.我正在使用java配置.这是我的存储库类:

@Repository
public interface UserRepository extends MongoRepository<User, String> {

    public User findByFirstName(String firstName);
    public List<User> findByLastName(String lastName);

}

这是使用UserRepository的服务:

@Service
public class TestService {

    @Autowired
    private UserRepository repository;

    public void save(User user) {
        repository.save(user);
    }
}

这是我使用服务的Controller的一部分:

@Controller
public class TestController {

    @Autowired
    private TestService service;

我的主要java配置类看起来像这样:

@Configuration
@EnableWebMvc
@EnableMongoRepositories
@Import({MjurAppConfig.class, MongoConfiguration.class})
@ComponentScan({"prv.makro.mjur.controller"})
public class MjurWebAppConfig extends WebMvcConfigurerAdapter {

MjurAppConfig:

@Configuration
@ComponentScan({"prv.makro.mjur.dao", "prv.makro.mjur.repository"})
public class MjurAppConfig {

    @Bean
    public User getUser() {
        return new User();
    }

    @Bean
    public TestService getTestService() {
        return new TestService();
    }
}

和mongo配置:

@Configuration
public class MongoConfiguration {

    @Bean
    public MongoFactoryBean mongo() {
        MongoFactoryBean mongo = new MongoFactoryBean();
        mongo.setHost("localhost");
        mongo.setPort(27017);
        return mongo;
    }

    @Bean
    public MongoTemplate mongoTemplate() throws Exception{
        return new MongoTemplate(mongo().getObject(),"mjur");
    }
}

例外:

    Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private prv.makro.mjur.repository.UserRepository 
prv.makro.mjur.service.impl.FirstService.repository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type [prv.makro.mjur.repository.UserRepository] 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)}

我正在寻找这个问题的解决方案,但我找不到任何东西.IMO组件扫描应该找到存储库,它应该将它绑定到spring上下文.可悲的是,它并没有像那样工作.

好的,问题在于@EnableMongoRepositories注释.

当我将包名添加到它的正文时(所以它看起来像:

@EnableMongoRepositories({"prv.makro.mjur.repository"}) )

我能够自动装配我的UserRepository
