Spring Boot - Exception Handling

Identify the issue in this centralized error handler code snippet:

@ControllerAdvice
public class GlobalErrorHandler {
  @ExceptionHandler(Exception.class)
  public ResponseEntity handleException(Exception ex) {
    return new ResponseEntity<>("An error occurred", HttpStatus.OK);
  }
}

AThe method should return void instead of ResponseEntity

BMissing @ResponseBody annotation on the method

C@ExceptionHandler must specify multiple exception classes

DReturning HTTP status OK (200) for an error is incorrect

Step-by-Step Solution

Solution:

Step 1: Analyze HTTP status usage
The handler returns HttpStatus.OK (200) even though an error occurred, which is misleading.
Step 2: Correct status code
Errors should return appropriate error status codes like 400 or 500 to indicate failure.
Final Answer:
Returning HTTP status OK (200) for an error is incorrect -> Option D
Quick Check:
Error responses should not use 200 OK [OK]

Quick Trick: Error responses must not return 200 OK [OK]

Common Mistakes:

Assuming @ResponseBody is required inside @ControllerAdvice

Returning void instead of ResponseEntity
