我无法运行我的应用程序 Spring Boot JPA Spring Data Service Rest

客户类包含在bnp.bmci.entities包中 

 @Entity 
public class Client implements Serializable{
    @Id 
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long codeClient;
    private String nomClient;

    @OneToMany(mappedBy="client",fetch=FetchType.LAZY) 
    private Collection<Compte> comptes;

    public Long getCodeClient() {
        return codeClient;
    }

    public void setCodeClient(Long codeClient) {
        this.codeClient = codeClient;
    }
    public String getNomClient() {
        return nomClient;
    }
    public void setNomClient(String nomClient) {
        this.nomClient = nomClient;
    }
    public Collection<Compte> getComptes() {
        return comptes;
    }
    public void setComptes(Collection<Compte> comptes) {
        this.comptes = comptes;
    }
    public Client() {
        super();
        // TODO Auto-generated constructor stub
    }
    public Client(Long codeClient, String nomClient, Collection<Compte> comptes) {
        super();
        this.codeClient = codeClient;
        this.nomClient = nomClient;
        this.comptes = comptes;
    }
    @Override
    public String toString() {
        return "Client [codeClient=" + codeClient + ", nomClient=" + nomClient + ", comptes=" + comptes + "]";
    }

    public Client(Long codeClient, String nomClient) {
        super();
        this.codeClient = codeClient;
        this.nomClient = nomClient;
    }

}

存储库包含在bnp.bmci.dao包中 

public interface ClientRepository extends JpaRepository<Client, Long>{

}

ClientMetier界面 

 package bnp.bmci.metier;

import java.util.List;
import bnp.bmci.entities.Client;

public interface ClientMetier {
    public Client saveClient(Client c);
    public List<Client> listClient();

}

ClientMetierImpl类 

package bnp.bmci.metier;
@Service
public class ClientMetierImpl implements ClientMetier{

        @Autowired
    private ClientRepository clientRepository;
    @Override
    public Client saveClient(Client c) {
        return clientRepository.save(c);
    }

    @Override
    public List<Client> listClient() {
        return clientRepository.findAll();
    }   

}

最后是bnp.bmci.service包中的ClientRestService 

@RestController
public class ClientRestService {
    @Autowired
    private ClientMetier clientMetier;

    @RequestMapping(value="/clients", method=RequestMethod.POST)
    public Client saveClient(@RequestBody Client c) {
        return clientMetier.saveClient(c);
    }

    @RequestMapping(value="/clients", method=RequestMethod.GET)
    public List<Client> listClient() {
        return clientMetier.listClient();
    }

}

答案 0 :(得分：2)

您的ClientRepository应该有@Repository，您应该已启用

您的配置中

@EnableJpaRepositories(basePackages = {"xxx.xxx.xxx.yyy"}) 

@Repository
public interface ClientRepository extends JpaRepository<Client, Long>{

}

答案 1 :(得分：-1)

您错过了为您的班级标记@Repository：

@Repository
public interface ClientRepository extends JpaRepository<Client, Long>{

}
