Java – Autowire MongoRepository in Spring MVC

javamongodbspring

I want to Autowire MongoRepository into my service class, and I'm not able to do this. I'm using java config.
This is my repository class:

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

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

}

This is the Service which uses UserRepository:

@Service
public class TestService {

    @Autowired
    private UserRepository repository;

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

This is part of my Controller which uses service:

@Controller
public class TestController {

    @Autowired
    private TestService service;

My main java config class looks like this:

@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();
    }
}

And mongo config:

@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");
    }
}

Exception:

    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)}

I was searching for resolution for this problem but I couldn't find anything.
IMO Component scan should find the repository and it should bind it to spring context. Sadly it's not working like that.

Best Solution

Ok, the problem was with @EnableMongoRepositories annotation.

When I have added package name to it's body (so it looked like:

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

I was able to autowire my UserRepository
