如何僅更新已更改的屬性 - Spring MVC mongoDB

Question

I'm using Spring Data MongoDB and Spring Data Rest to create a REST API which allows GET, POST, PUT and DELETE operations on my MongoDB database and it's all working fine except for the update operations (PUT). 僅當我在請求正文中發送完整的 object 否則變量未在請求中發送它是 null 時才有效。有人可以指導我解決這個問題。

@PutMapping("/update/{id}")
    public void update(@Valid @RequestBody Facture facture, @PathVariable("id") String id){
        Optional<Facture> factureData = factureRepository.findById(id);

            facture.setId_facture(id);
            this.factureRepository.save(facture);
}
