Why does the request not see the body?

Question

Java

There is a Delete controller that throws an error and does not want to delete the user by body.

@DeleteMapping("*/deleteoneusers")
    public void deleteUsers(@RequestBody User user) {
        userRepository.delete(user);
    }

I send the user body that comes with the get request.
What's the matter, why does it say that the request body is empty?
Same thing with this controller

Answer 1

According to the standard, delete requests cannot have a body - RFC 7231 .

Answer 2

because you are sending an array and expecting one element.
and it is not yet clear which content-type is set.
Why the whole object at all, when id is enough for deletion?

@DeleteMapping("/users/{id}")
void deleteUser(@PathVariable Long id) {
  repository.deleteById(id);
}
