How to implement guide with custom scenarios handling in spring boot rest api returning incorrect status code
Hey everyone, I'm running into an issue that's driving me crazy. I've looked through the documentation and I'm still confused about I'm currently working on a Spring Boot REST API (version 2.6.0) and I've implemented a custom exception handler using `@ControllerAdvice`. However, I'm working with an scenario where certain exceptions are not returning the expected HTTP status codes, which leads to confusion on the client side. I've defined the handler methods to return specific behavior responses, but for some reason, a `NullPointerException` gets translated to a 500 Internal Server behavior instead of the more specific behavior response I've set up. Here's a snippet of my exception handler: ```java @ControllerAdvice public class GlobalExceptionHandler { @ExceptionHandler(ResourceNotFoundException.class) public ResponseEntity<ErrorResponse> handleResourceNotFound(ResourceNotFoundException ex) { ErrorResponse errorResponse = new ErrorResponse("Resource not found", LocalDateTime.now()); return new ResponseEntity<>(errorResponse, HttpStatus.NOT_FOUND); } @ExceptionHandler(Exception.class) public ResponseEntity<ErrorResponse> handleGeneralException(Exception ex) { ErrorResponse errorResponse = new ErrorResponse("An unexpected behavior occurred", LocalDateTime.now()); return new ResponseEntity<>(errorResponse, HttpStatus.INTERNAL_SERVER_ERROR); } } ``` When I throw a `NullPointerException` in one of my service methods and let it propagate, it seems to bypass my custom handler for `ResourceNotFoundException`. I even tried logging the stack trace to see if it's caught somewhere else, but it just goes straight to the default Spring behavior handler. I've verified that my `@ControllerAdvice` is being picked up by Spring, as it correctly handles other specific exceptions. Is there something Iām missing in the configuration, or do I need to explicitly handle `NullPointerException` as well? I've also looked into using `@ResponseStatus` on my exceptions, but it didn't seem to resolve the scenario. Any insights would be greatly appreciated! How would you solve this? For context: I'm using Java on Linux.
