What's the correct way to handle unexpected exceptions in Spring Boot?

[lean ivy]

why would u .printStackTrace it?

[pulsar folio]

Because if a user encounters an internal server error, I want to be able to check what happened?

[lean ivy]

I would log things into log file

@ExceptionHandler(NoResourceFoundException.class)
public ResponseEntity<ErrorResponse> handleNoResourceFoundException(NoResourceFoundException exception) {
    return ResponseEntity.notFound().build();
}

you can do something like this

[pulsar folio]

I don't think a free host(which I'm using) would allow that lol

[lean ivy]

then try to return something with ResponseEntity

you can return status, message and other things too

[pulsar folio]

That might work, but do people really do this in every backend project?

Spring tutorials on google are extremely inconsistent and just weird

[lean ivy]

@ExceptionHandler(MethodArgumentNotValidException.class)
    public ResponseEntity<Object> handleMethodArgumentNotValid(MethodArgumentNotValidException ex) {
        List<ErrorDetails> errors = new ArrayList<>();
        ex.getBindingResult().getFieldErrors().forEach(error -> {
            String errorMessage = error.getDefaultMessage();
            String field = error.getField();
            errors.add(new ErrorDetails(errorMessage, field, LocalDateTime.now()));
        });
        log.error(ex.getMessage(), errors);
        return ResponseEntity.badRequest().body(errors);
    }

from one open source spring project

Formatted code

@ExceptionHandler(MethodArgumentNotValidException.class ) public ResponseEntity<Object> handleMethodArgumentNotValid(MethodArgumentNotValidException ex) {
  List<ErrorDetails> errors = new ArrayList<>();
  ex.getBindingResult().getFieldErrors().forEach(error -> {
    String errorMessage = error.getDefaultMessage();
    String field = error.getField();
    errors.add(new ErrorDetails(errorMessage, field, LocalDateTime.now()));
  }
  );
  log.error(ex.getMessage(), errors);
  return ResponseEntity.badRequest().body(errors);
}

spring security automatically response with notFound if an internal exception happens

[pulsar folio]

I'm not currently using spring security

[soft basin]

yeah, just saying

it is a security issue to give the user internal details and stuff

[pulsar folio]

I agree, that's why I wanted to prevent exception messages from leaking

[lean ivy]

you can catch that NotFound and return with ResponseEntity

[soft basin]

why not spring security then?

it does that for you

[pulsar folio]

I guess that's what I will do

[soft basin]

but why

[pulsar folio]

I don't have a need for a user system or anything like that

[soft basin]

and?

[pulsar folio]

All my endpoints are public

[soft basin]

you can disable authentication 🤷‍♂️

[lean ivy]

i think he doesn't need security or maybe just not good at security

[pulsar folio]

which defeats the purpose of using spring security lol

[soft basin]

and you asked for this:

That might work, but do people really do this in every backend project?
and no, people dont do it manually, it is provided by spring security

[soft basin]

no spring security is sooooo much more than just authentication

[pulsar folio]

as I said I just don't need it currently

[soft basin]

you should use it though 🤷‍♂️
but fine

[lean ivy]

Anyways, try to make it in that way
but I suggest you to use security in later projects

[pulsar folio]

I do use security in bigger projects...

[soft basin]

why not use it in smaller projects?

whatever

if you really want to do it yourself for some obscure reason then sure, do it like it was mentioned before with exception handler

[pulsar folio]

it's not obscure, but okay

there's 0 problems with my way

You don't use a big library for just 1% of its functionality

it makes the file size bigger, and just makes no sense in general

[soft basin]

spring security is much more 🤷‍♂️

and you shouldnt use spring in the first place if you care about micro optimization and file size lol

[pulsar folio]

I never said it doesn't have more content, I said that I don't need any of it

this argument has no meaning
