I have the following repository, as simple as this:
package br.com.portal.repository;
public interface UserRepository extends CrudRepository<User, Long> {
@Query("SELECT u FROM User WHERE u.login = :login")
User findByLogin(@Param("login") String login);
}
Here, it's supposed to inherit all the common crud operations defined in CrudRepository and also expose the findByLogin function.
Most examples, if not all, do not annotate such repository with the @Repository annotation. Why is that? Is there a need to implement this interface or does the @Query somehow does it behind the scenes?
Here is what I currently have:
package br.com.portal.service;
public interface UserService {
User findByLogin(String login);
}
@Service
public class UserServiceImpl implements UserService {
private UserRepository repository;
@Autowired
public UserServiceImpl(UserRepository repository) {
this.repository = repository;
}
User findByLogin(String login) {
return repository.findByLogin(login);
}
}
And the spring-mvc.xml:

I am not using Spring Boot.
With the current above informations, we should be able to reproduce the following error:
Error creating bean with name 'userServiceImpl' defined in file xxx: Unsatisfied dependency expressed through constructor parameter 0; nested exception is NoSuchBeanDefinitionException: No qualifying bean of type 'UserRepository'
Am I missing something?
