我正在尝试制作一个页面来编辑我的 Subcategory 条目，它与 Category 进入。
这是你的名字 Category 班

@Entity
@Data
public class Category {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String name;
    private String description;

    @OneToMany(mappedBy = "category", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JsonIgnore
    private Set<SubCategory> subCategories = new HashSet<>();

}

这是你的名字 Subcategory 班

@Entity
@Data
public class SubCategory {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String name;
    private String description;

    @ManyToOne(optional = false, fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    private Category category = new Category();

}

这是你的名字 SubcategoryController ```
@Controller
@RequestMapping("/subcategory")
public class SubcategoryController {

@Autowired
private SubcategoryService subcategoryService;
@Autowired
private CategoryService categoryService;

// ... other methods for other pages, which I don't think are causing the problem

@GetMapping("/new")
public String addSubcategory(Model model) {
    model.addAttribute("subcategory", new SubCategory());
    model.addAttribute("categories", categoryService.findAll());
    model.addAttribute("action", "new");
    return "subcategory/edit";
}

@PostMapping("/new")
public String addSubcategory(@ModelAttribute SubCategory subCategory) {
    subCategory = subcategoryService.save(subCategory);
    return "redirect:/subcategory/" + subCategory.getId();
}

@GetMapping("/{subcategoryId}/edit")
public String edit(@PathVariable int subcategoryId, Model model) {
    model.addAttribute("subcategory", subcategoryService.findById(subcategoryId));
    model.addAttribute("action", "edit");
    return "subcategory/edit";
}

@PostMapping("/{subcategoryId}/edit")
public String editPOST(@PathVariable int subcategoryId, @ModelAttribute SubCategory subCategory) {
    subCategory.setId(subcategoryId);
    subcategoryService.save(subCategory);
    return "redirect:/subcategory/" + subcategoryId;
}

}

这里是 `edit.html` ```
<!DOCTYPE html>

                    </select>
                </label>

                <div>
                    <input type="submit" value="Submit" class="btn btn-success" />
                    <input type="reset" value="Reset" class="btn btn-outline-success"/>
                    <!--                    <input type="submit" value="Delete" class="btn btn-danger"/>-->
                </div>

            </form>

            <a th:if="${action} == 'edit'" th:href="'delete'" class="btn btn-danger">Delete Subcategory</a>
        </div>
    </div>
</div>

<div th:replace="common/header :: body-bottom-scripts"></div>
</body>
</html>

上面的代码在添加新的子类别时起作用，但是，当试图编辑现有的子类别时，会显示以下错误消息
