Issue
When I run my application, upon giving correct data in Postman, I get something like this.
{
"sportsId":"1000",
"noOfPlayers":"22",
"sportsName":"Hockey",
"sportsType":"Outdoor"
}
Response
{
"sportsId":"1000",
"sportsName":"Hockey",
"sportsType":"Outdoor"
}
In case any exception is handled, like entering the same data, this would be the response of custom exception handling.

"message": "Sport already Exist!",
"path": "/api/v1/sportsEvent/addSport"
}
But I want the response to be in this way
{
"status":500,
"message":"Sport already Exist!"
}
Could someone please help me what all changes I require to undergo so that I could simply my response?
Solution
In your Exceptions package, add a RestResponseEntityExceptionHandler.java class which extends to ResponseEntityExceptionHandler.
Annotate the class with @ExceptionalHandler(Class_to_be_handeled.java) @ResponseBody @ResponseStatus(HttpStatus.NOT_FOUND) annotations.
Finally, create a ExceptionMessage.java class to handle the response.
Please find the below code for further clarification.
RestResponseEntityExceptionHandler.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;
}
}
ExceptionMessage.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;
}
}
Final Response :
{
"httpStatus": "BAD_REQUEST",
"msg": "Sport already Exist!"
}
Hope this is helpful!
you can ping me any time.
