spring - Java Spring 创建新记录而不是更新现有记录

问题描述

我正在使用Javaspringboot，我尝试更新现有记录，但它创建了一个新记录，我一直在寻找原因，但我被卡住了。任何建议将不胜感激。我的商店控制器：

@GetMapping("/store/update/{idStore}")
    public String updateStoreForm(
            @PathVariable Long idStore,
            Model model
    ) {

        StoreModel store = storeService.getStoreByidStore(idStore);
        List<ManagerModel> listManager = managerService.getManagerList();
        model.addAttribute("listManager", listManager);
        model.addAttribute("store", store);
        return "form-update-store";
    }

    @PostMapping("/store/update")
    public String updateStoreSubmit(
            @ModelAttribute StoreModel store,
            Model model
    ) {
        LocalTime now = LocalTime.now();
        if ( (now.isBefore(store.getWaktuBuka()) || now.isAfter(store.getWaktuTutup())) ){
            storeService.updateStore(store);
            model.addAttribute("idStore", store.getIdStore());
            return "update-store";
        }
        return "error-page";
    }

我的模型：

public class StoreModel implements  Serializable {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long idStore;



@NotNull
@Column(nullable = false)
@DateTimeFormat(pattern = "HH:mm")
private LocalTime waktuBuka;

@NotNull
@Column(nullable = false)
@DateTimeFormat(pattern = "HH:mm")
private LocalTime waktuTutup;

//storecode
@NotNull
@Size(max=10)
@Column(name="kode_store", nullable = false, unique = true)
private String kodeStore;

//relasi OnetoOne ke manager
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "id_manager")
private ManagerModel manager;

@OneToMany(mappedBy = "store")
private List<StorebobateaModel> storebobatea;
}

我的提交表格：

数据库：

它创建一个新的“id_store”而不是更新现有的。我该如何解决？
