Vielen Dank für Ihre Hilfe.

Answer 1

Sie sollten versuchen, @Component anstelle von @Component ("clientDao") zu verwenden. Dadurch wird Ihre Bean mit dem Namen "Clients" registriert. Oder wenn Sie dies nicht tun möchten, dann ist die zweite Option @Qualifier ("clientDao"), die Sie einfach hinter @Atuwire setzen können. wie

@Autowired 
@Qualifier("clientDao") 
public void setClientDao(Clients clientDao){ 
    this.clientDao = clientDao; 
} 

Answer 2

Ändern Sie Ihren ClientService und ClientController wie unten.

ClientService:

@Service 
public class ClientService { 

    private Clients clientDao; 

    @Autowired 
    @Qualifier("clientDao") 
    public void setClientDao(Clients clientDao){ 
     this.clientDao = clientDao; 
    } 

    public void addClient(Client client) { 
     clientDao.create(client); 
    } 

} 

ClientController:

@Controller 
public class ClientController { 


    private ClientService clientService; 

    @Autowired 
    @Qualifier("clientService") 
    public void setService(ClientService service) { 
     this.clientService = service; 
    } 



    @RequestMapping(value = "/doAddClient", method = RequestMethod.POST) 
    public String doAddClient(@Valid Client client){ 
     clientService.addClient(client); 


     return "order"; 
    } 

} 

Sie haben über @Autowired und @Qualifer in Spring.you zu lernen, kann es here lesen.
