UnsatisfiedDependencyException Error creating bean with name

Question

 I'm trying to create a Spring CRUD application. I'm getting these errors:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'clientController': Unsatisfied dependency expressed through method 'setClientService' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'clientService': Unsatisfied dependency expressed through field 'clientRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.kopylov.repository.ClientRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

And this:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'clientService': Unsatisfied dependency expressed through field 'clientRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.kopylov.repository.ClientRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

ClientController:

@Controller
public class ClientController {
private ClientService clientService;

@Autowired
@Qualifier("clientService")
public void setClientService(ClientService clientService){
    this.clientService=clientService;
}
@RequestMapping(value = "registration/add", method = RequestMethod.POST)
public String addUser(@ModelAttribute Client client){
    this.clientService.addClient(client);
return "home";
}
}

ClientServiceImpl:

@Service("clientService")
public class ClientServiceImpl implements ClientService{

private ClientRepository clientRepository;

@Autowired
@Qualifier("clientRepository")
public void setClientRepository(ClientRepository clientRepository){
    this.clientRepository=clientRepository;
}



@Transactional
public void addClient(Client client){
    clientRepository.saveAndFlush(client);
}
}

ClientRepository:

public interface ClientRepository extends JpaRepository<Client, Integer> {

}

Can someone help me solve these errors?

Comments

@Autowire =>  private ClientRepository clientRepository;

Answer 1

i had the same issues i solve it by adding the service package to xml configuration file

<!-- Add support for component scanning -->

<context:component-scan base-package="com.manage.customer.application,

com.manage.customer.dao,com.manage.customer.entity,com.manage.customer.service" />

Answer 2

The @Repository tag should be added to the client repository. Your current setup prevents Spring from scanning the class and learning about it. The Client Repository class will not be found at the time of booting and wiring. If this doesn't help you then try adding a @Service annotation to the ClientService (interface). You don't have to supply a name with the optional argument @Service because your service should only have one implementation ("clientService"). Using the name of the interface, Spring will automatically generate it.

I hope this helps you.

Answer 3

Annotate ClientRepository with @Repository

Answer 4

You dont need specify @Service with "clientService" @Service("clientService")

Just use 

@Service()
public class ClientServiceImpl ...

for all Services classes and Spring up instances for all

Answer 5

Add @Repository annotation in repository interface and try it.
