如何在 ResponseEntity 中返回已创建状态 (201 HTTP)

Question

There is a Spring-MVC application. In controllers, when returning the results of methods, I return via ResponseEntity<> . On success, I return ( 200 statutes) the OK -method. But when creating something, I would like to return the CREATED -method ( 201 status). I just can't understand what kind of URL to ask in parentheses when calling through CREATED . How can this be implemented?

Now I have such an implementation:

@PostMapping("/create/dish")
    ResponseEntity<Dish> createDish(@Valid @RequestBody DishDTO dishDTO) {

        return ResponseEntity.ok(cookService.createDish(dishDTO.getDishName(), dishDTO.getAboutDish(), dishDTO.getDishType(),
                dishDTO.getCookingTime(), dishDTO.getWeight(),
                dishDTO.getDishCost(), dishDTO.getCooksId()));
    }

I want to remake it like this to make it work(now it not work):

@PostMapping("/create/dish")
    ResponseEntity<Dish> createDish(@Valid @RequestBody DishDTO dishDTO) {

        return ResponseEntity.created(cookService.createDish(dishDTO.getDishName(), dishDTO.getAboutDish(), dishDTO.getDishType(),
                dishDTO.getCookingTime(), dishDTO.getWeight(),
                dishDTO.getDishCost(), dishDTO.getCooksId()));
    }

PS I don't have a frontend at all. All through Swagger or PostMan.

Answer 1

Just return this way:

return new ResponseEntity<Dish>(cookService.createDish(...), HttpStatus.CREATED)

Making sure you have imported org.springframework.http.HttpStatus

Answer 2

You can use

return new ResponseEntity(cookService.createDish(...), HttpStatus.CREATED);

Answer 3

You can use

    ResponseEntity.created(ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}").buildAndExpand(savedObjectId).toUri()).build()

Answer 4

If you want to create a 201 (CREATED) response without a body, then use:

ResponseEntity.status(HttpStatus.CREATED).build()

Answer 5

Alternatively to return 201 (Created) status you can also dispose of ResponseEntity and set @ResponseStatus(HttpStatus.CREATED) for RestController method like this

@PostMapping("/create/dish")
@ResponseStatus(HttpStatus.CREATED) 
Dish createDish(@Valid @RequestBody DishDTO dishDTO) {
    return cookService.createDish(...);
}
