Spring BeanCreationException错误

Question

我在研究STS数据库连接。

我试着和我当地的数据库联系。

@Controller
public class HomeController {

@Autowired private AccountRepository AccountRepository;

//@Autowired
//private AccountDaoImpl AccountDaoImpl;

//private AccountDao AccountDao;

@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
    return "home";
}

@RequestMapping(value = "/home", method = RequestMethod.GET)
public String homehome(Locale locale, Model model) {
    return "home";
}
@RequestMapping(value = "/login", method = RequestMethod.POST)
public @ResponseBody List<Account> getUserList() {

    return AccountRepository.findAll();
    //EntityManagerFactory emf = Persistence.createEntityManagerFactory("NewPersistenceUnit");
    //AccountDaoImpl.entityManager = emf.createEntityManager();
    //return AccountDaoImpl.getAccount();
}
//@RequestMapping(value = "/login", method = RequestMethod.POST)
//public String login(Locale locale, Model model) {
//  
//  EntityManagerFactory emf = Persistence.createEntityManagerFactory(
//  return "login";
//}
}

@Service
public interface AccountRepository extends JpaRepository<Account, Long> {
}

 @Entity
 @Table(name = "Account")
 public class Account implements Serializable {
 @Id
 @Column(name = "email")
 private String email;
 @Column(name = "id")
 private String id;
 @Column(name = "password")
 private String password;

 public void setEmail(String email) {
     this.email = email;
 }

 public String getEmail() {
     return email;
 }

 public String getId() {
     return id;
 }

 public void setId(String id) {
     this.id = id;
 }

 public String getPassword() {
     return password;
 }

 public void setPassword(String password) {
     this.password = password;
 }

类型异常报告

servlet的消息servlet.init（）appServlet引发异常

说明服务器遇到一个内部错误，使其无法满足此请求。

我想避免这个错误。

我该怎么办？

根大小写是：“没有找到com.myongjoon.spring.AccountRepository类型的合格bean”。

这是因为，您的代码看起来像是试图为存储库使用Spring-Data-Jpa。但这需要：

您的存储库只是一个接口（没有@service注释）和

您需要通过以下方式启用Spring-Data-Jpa
