How you are handling exceptions in your applications globally, not in method level or class level but in application level?
To handle exceptions globally in my application, I use a global exception handler. This is a central place in the application (not inside individual methods or classes) where all unhandled errors are caught. For example, in Java Spring Boot, I use @ControllerAdvice with @ExceptionHandler. This way, any error that happens anywhere in the application is handled in one place, allowing me to log the error, show a user-friendly message, and keep the application running smoothly. This makes exception management easier and more consistent across the whole application.
Example
In a Spring Boot application, I create a class with @ControllerAdvice and write a method with @ExceptionHandler to catch all exceptions globally:
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(Exception.class)
public ResponseEntity<String> handleAllExceptions(Exception ex) {
// Log the exception and return a user-friendly message
return new ResponseEntity<>
("Something went wrong. Please try again later.",
HttpStatus.INTERNAL_SERVER_ERROR);
}
}
This way, any unhandled exception in the whole application will be caught by this handler.
