当我运行我的应用程序时，在Postman中给出正确的数据后，我得到了如下所示的结果。

{
 "sportsId":"1000",
 "noOfPlayers":"22",
 "sportsName":"Hockey",
 "sportsType":"Outdoor"
}

回应

{
 "sportsId":"1000",
 "sportsName":"Hockey",
 "sportsType":"Outdoor"
}

在处理任何异常的情况下，比如输入相同的数据，这将是自定义异常处理的响应。

"message": "Sport already Exist!",
"path": "/api/v1/sportsEvent/addSport"
}

但我希望回应是这样的

{
  "status":500,
  "message":"Sport already Exist!"
}

有人能帮我什么所有的变化，我需要经历，使我可以简单地我的React？

在您的异常包中，添加一个扩展到响应实体异常处理程序的 * RestResponseEntityException Handler.java* 类。
使用@ExceptionalHandler(Class_to_be_handeled.java) @ResponseBody @ResponseStatus(HttpStatus.NOT_FOUND)注解来注解类别。
最后，创建一个ExceptionMessage.java类来处理响应。
请查看以下代码以了解进一步的说明。

静态响应实体异常处理程序.java

@ControllerAdvice
public class RestResponseEntityExceptionHandler extends 
ResponseEntityExceptionHandler {

@ExceptionHandler(Class_to_be_handeled.class)
@ResponseBody
@ResponseStatus(HttpStatus.BAD_REQUEST)
public ExceptionMessage sportInsertionExceptionHandler(SportInsertionException 
exception)
{
    ExceptionMessage message = new ExceptionMessage(HttpStatus.BAD_REQUEST, 
    exception.getMessage());

    return message;
}
}

异常消息.java

public class ExceptionMessage {

private HttpStatus httpStatus;
private String msg;

public ExceptionMessage() {
}

public ExceptionMessage(HttpStatus httpStatus, String msg) {
    this.httpStatus = httpStatus;
    this.msg = msg;
}

public HttpStatus getHttpStatus() {
    return httpStatus;
}

public void setHttpStatus(HttpStatus httpStatus) {
    this.httpStatus = httpStatus;
}

public String getMsg() {
    return msg;
}

public void setMsg(String msg) {
    this.msg = msg;
}
}

最终答复：

{
 "httpStatus": "BAD_REQUEST",
 "msg": "Sport already Exist!"
}

您可以返回一个HttpStatus.INTERNAL_SERVER_ERROR，并在正文中包含一条消息，请查看下面代码。

@RequestMapping("/insert")
    public ResponseEntity<Object> insertData(HttpServletRequest request){
        if ( checkDuplicateData(request) ) {
        throw new DuplicateDataApiException();
     } else{
        return new ResponseEntity.ok("Data Inserted successfully");
     } 
    }

说明：它将检查数据是否重复，然后抛出服务器异常，否则需要响应ok/200
@此处为异常处理程序代码

@ExceptionHandler(value = DuplicateDataApiException.class)
    public ResponseEntity<Object> duplicateDataApiException(DuplicateDataApiException exception){
        return new ResponseEntity<>("Duplicate Data Error", HttpStatus.INTERNAL_SERVER_ERROR);
    }

我希望，它能帮上忙！
