Best practice to send response in spring boot

Question

I\'m coding REST Api-s in spring boot. I want to make sure that my code is readable to front-end developers using swagger API development tool (Swagger). For example

Answer 1

I would recommend to do it like this .

@GetMapping("/getOne")
public Response getOne(@RequestParam String id) {
        ResponseEntity resbranch;
        ResponseEntity reserror;
        try {
            resbranch=new ResponseEntity(branchService.getOne(id), HttpStatus.OK);
            return Response.status(200).entity(resbranch).build();

        } catch (Exception e) {
            reserror=new ResponseEntity(new FindError(e.getMessage()), HttpStatus.BAD_REQUEST);
            return Response.status(400).entity(reserror).build();
        }
    }

200 is for OK and 400 is for bad request. Here there wont be anymore ambiguous types..
