  }

@PostMapping(value = "/posts")
public UserRest createUser(@RequestBody UserDetailsRequestModel requestUserDetails)
{
	UserRest returnValue = new UserRest();

	UserDto userDto = new UserDto();
	BeanUtils.copyProperties(requestUserDetails, userDto);
	UserDto createdUser = userService.createUser(userDto);
	BeanUtils.copyProperties(createdUser, returnValue);
	return returnValue;

@PutMapping(value = "/contacts/{contactId}")
public ResponseEntity<Contact> updateContact(@RequestBody Contact contact,
		@PathVariable long contactId) {
	...
	return ...
}

@PatchMapping("/patch")
public @ResponseBody ResponseEntity<String> patch() {
	return new ResponseEntity<String>("PATCH Response", HttpStatus.OK);
}

@DeleteMapping(value = "/posts/{id}")
public ResponseEntity<Long> deletePost(@PathVariable Long id) {

	var isRemoved = postService.delete(id);

	return new ResponseEntity<>(id, HttpStatus.OK);
