java - Spring boot 返回 400 缺少构造函数，没有堆栈跟踪

Question

我有一个邮寄电话

public Test postTest(@RequestBody Test test) {
}


public class Test {
    @JsonProperty("EMAIL_ADDRESS")
    @NotNull(message = "EMAIL_ADDRESS_NOT_NULL")
    @Size(min = 1, message = "EMAIL_ADDRESS_NOT_EMPTY")
    @Email(flags = Flag.CASE_INSENSITIVE, message = "EMAIL_INVALID")
    private String emailAddress;

    public ForgetPassword(
            @NotNull(message = "EMAIL_ADDRESS_NOT_NULL") @Size(min = 1, 
            message = "EMAIL_ADDRESS_NOT_EMPTY") @Email(flags = 
            Flag.CASE_INSENSITIVE, 
            message = "EMAIL_INVALID") String emailAddress) {
        super();
        this.emailAddress = emailAddress;
    }

    public String getEmailAddress() {
        return emailAddress;
    }

    public void setEmailAddress(String emailAddress) {
        this.emailAddress = emailAddress;
    }
}

我缺少默认构造函数，当我尝试发帖时它不断返回错误的请求。如果我添加默认构造函数，它就可以工作。它甚至不会抛出堆栈跟踪。我正在使用自定义模板来发回响应。我正在重写 BadRequestException 以发回自定义消息。

@ResponseStatus(HttpStatus.BAD_REQUEST)
public class BadRequestException extends RuntimeException {
    public BadRequestException(String message) {
        super(message);
    }
}

是否有任何我应该重写的方法来捕获此类异常。我希望能够知道为什么会出现问题并能够看到堆栈跟踪。

您可以使用@ControllerAdvice定义全局异常处理程序。您可以使用@ExcecptionHandler 在那里放置任意数量的处理程序。您可以记录 errorTrace 以进行调试。

package com.startwithjava.exception;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;

@ControllerAdvice
public class ApiExceptionHandler {
    @ExceptionHandler(Exception.class)
    public ResponseEntity<Object> handlerGenericError(Exception ex){
        ex.printStackTrace();
        return new ResponseEntity<>(ex.getMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
    }
    @ExceptionHandler(BadRequestException.class)
    public ResponseEntity<Object> handlerBadRequest(BadRequestException ex){
        return new ResponseEntity<>(ex.getMessage(), HttpStatus.NOT_FOUND);
    }
}
