Why do we use ResponseEntity in a RESTful Service?

Comment

ResponseEntity is used when you need to change HTTP headers or HTTP status code based upon your business logic or incoming request. ResponseEntity wraps the original object as its body which is optional. If you want to return an object or null, ResponseEntity will work in either way.

@PostMapping("/users")
public ResponseEntity<Object> createUser(
@Valid @RequestBody User user) {
User savedUser = service.save(user);
URI location = ServletUriComponentsBuilder
.fromCurrentRequest()
.path("/{id}")
.buildAndExpand(savedUser.getId()).toUri();
return ResponseEntity.created(location).build();
}
