My application depends on a set of external Spring Interceptors which throw an exception and my service returns an HTTP 500. I would like to catch the exception, and if the stack trace matches some text, I would like to return a HTTP 400 instead. The exception thrown is of type NestedServletException.

I have tried implementing a @ControllerAdvice but it doesn’t seem to catch the NestedServletException.

@ControllerAdvice
public class ErrorHandlingController {

    @ExceptionHandler(NestedServletException.class)
    public ResponseEntity<String> exceptionHandler(NestedServletException e) {
        return new ResponseEntity<>(e.getMessage(), HttpStatus.BAD_REQUEST);
    }
}

Any idea how to catch this? The stack trace looks something like:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is: The requested secret was not found.
