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();
}
}

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>{
}
