put, delete 요청은
톰캣이 파싱해주지 않는다
따라서

//스프링부트
@DeleteMapping("todo/{no}")
public List<TodoVO> todo(@PathVariable("no") int no) {
	service.deleteTodo(no);
	return service.selectTodos();
}

//뷰
axios
  .delete(`http://localhost:8282/TodoAppBackend/todo/${no}`)
  .then((response) => {})
  .catch((error) => {});
