Spring Boot 层架构休息验证

Question

我想验证我的 Spring Boot 项目，但是 当我从控件访问存储库时，我得到了正确的错误。

CustomerController.java

@Autowired
private CustomerRepository customerRepository;



@PostMapping("/addcustomer")
public Customer addCustomer(@Valid @RequestBody Customer customer) {
    return customerRepository.save(customer);
    
}

当我使用分层架构时，我在控制台上收到错误

CustomerController.java

@Autowired
private CustomerService customerService;


    

@PostMapping("/addcustomer")
public Customer addCustomer(@Valid @RequestBody CustomerDto customer) {
    return customerService.save(customer);
    
}

客户.java

@Entity
public class Customer {

@Id
private String nickName;

@NotNull
@Size(min = 2 , max = 20 , message = "Incorret name")
private String name;

@NotNull
@Size(min = 2 , max = 20 , message = "Incorret surname")
private String surname;

@NotBlank
@Email
private String e_mail;

@NotNull
@Size(min = 6, max = 20, message = "Your password should be at least 6 character")
private String password;

@NotNull
private long balance;

@OneToOne(cascade = CascadeType.PERSIST)
@JoinColumn(name = "car_id")
@Nullable
private Car car;

@OneToOne(mappedBy = "customer")
private Accept accept;



public Customer() {
}

public Customer(String nickName, String name, String surname, String e_mail, String password, long balance, Car car) {
    super();
    this.nickName = nickName;
    this.name = name;
    this.surname = surname;
    this.e_mail = e_mail;
    this.password = password;
    this.balance = balance;
    this.car = car;
}

public String getNickName() {
    return nickName;
}

public void setNickName(String nickName) {
    this.nickName = nickName;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getSurname() {
    return surname;
}

public void setSurname(String surname) {
    this.surname = surname;
}

public String getE_mail() {
    return e_mail;
}

public void setE_mail(String e_mail) {
    this.e_mail = e_mail;
}

public String getPassword() {
    return password;
}

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

public long getBalance() {
    return balance;
}

public void setBalance(long balance) {
    this.balance = balance;
}

public Car getCar() {
    return car;
}

public void setCar(Car car) {
    this.car = car;
}

}

CustomerDto.java

public class CustomerDto {

private String nickName;
private String name;
private String surname;
private String e_mail;
private String password;
private long balance;
@Nullable
private long carID;


public String getNickName() {
    return nickName;
}
public void setNickName(String nickName) {
    this.nickName = nickName;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getSurname() {
    return surname;
}
public void setSurname(String surname) {
    this.surname = surname;
}
public String getE_mail() {
    return e_mail;
}
public void setE_mail(String e_mail) {
    this.e_mail = e_mail;
}
public String getPassword() {
    return password;
}
public void setPassword(String password) {
    this.password = password;
}
public long getBalance() {
    return balance;
}
public void setBalance(long balance) {
    this.balance = balance;
}
public long getCarID() {
    return carID;
}
public void setCarID(long carID) {
    this.carID = carID;
}
public CustomerDto() {
    super();
}
public CustomerDto(String nickName, String name, String surname, String e_mail, String password, long balance,
        long carID) {
 
    this.nickName = nickName;
    this.name = name;
    this.surname = surname;
    this.e_mail = e_mail;
    this.password = password;
    this.balance = balance;
    this.carID = carID;
}


}

CustomerServiceImpl.java

@Override
public Customer save(CustomerDto customerdto){
    try {
        Customer customer = new Customer();
        convertToEntity(customer, customerdto);

        return customerRepository.save(customer);
    }
    
    catch (Exception e) {
        e.printStackTrace();
        return null;
    }
    
    
}

客户服务.java

public interface CustomerService {

public Customer save(CustomerDto customerDto);

public void update(CustomerDto customerDto);

public void delete();

public void convertToDto(Customer customer, CustomerDto customerDto);

public void convertToEntity(Customer customer, CustomerDto customerDto);

public List<CustomerDto> customerList();

 
public ResponseEntity<CustomerDto> findByUserName(String nickName) throws ResourceNotFoundException;

}

CustomerRepository.java

@Repository
public interface CarRepository extends CrudRepository<Car, Long>

GlobalExceptionHandler.java

@ControllerAdvice
public class GlobalExceptionHandler {

@ExceptionHandler(ResourceNotFoundException.class)
public ResponseEntity<?> resourceNotFoundException(ResourceNotFoundException ex, WebRequest request){
    ErrorDetails errorDetails = new ErrorDetails(new Date(), ex.getMessage(), request.getDescription(false));
    return new ResponseEntity<>(errorDetails,HttpStatus.NOT_FOUND);             
}


@ExceptionHandler(Exception.class)
public ResponseEntity<?> globalExceptionHandler(Exception ex, WebRequest request){
    ErrorDetails errorDetails = new ErrorDetails(new Date(),ex.getMessage(), request.getDescription(false));
    return new ResponseEntity<>(errorDetails, HttpStatus.INTERNAL_SERVER_ERROR);
}


@ExceptionHandler(MethodArgumentNotValidException.class)
public ResponseEntity<?> customValidationErrorHanding(MethodArgumentNotValidException exception){
    ErrorDetails errorDetails = new ErrorDetails(new Date(), "Validation Error!",
            exception.getBindingResult().getFieldError().getDefaultMessage());
    return new ResponseEntity<>(errorDetails,HttpStatus.BAD_REQUEST);
}


 }

ErrorDetails.java

public class ErrorDetails {
public ErrorDetails(Date timestamp, String message, String details) {
    super();
    this.timestamp = timestamp;
    this.message = message;
    this.details = details;
}
public Date getTimestamp() {
    return timestamp;
}
public void setTimestamp(Date timestamp) {
    this.timestamp = timestamp;
}
public String getMessage() {
    return message;
}
public void setMessage(String message) {
    this.message = message;
}
public String getDetails() {
    return details;
}
public void setDetails(String details) {
    this.details = details;
}
private Date timestamp;
private String message;
private String details;


}

SpringRentApplication.java

@SpringBootApplication
public class SpringRentApplication {

public static void main(String[] args) {
    SpringApplication.run(SpringRentApplication.class, args);
}

 }

我的 GlobalExceptionHandler.java 和 ErrorDetail.java 代码没有错误。我已经说过，当我从控制器访问存储库时，它可以正常工作。

Answer 1

当控制器收到请求时，您试图在绑定时捕获验证错误。为此，您必须在 CustomerDTO 对象中添加验证标签。这样做，您将能够捕获如下绑定错误：

@PostMapping("/addcustomer")
public Customer addCustomer(@Valid @RequestBody CustomerDto customer, BindingResult theBindingResult) {

    if (theBindingResult.hasErrors()){
             //Do something here, like returning the view that has the form to create a new customer
    }
    return customerService.save(customer);
    
}
