spring-boot - 我无法更新或删除属性。Get 和 Post 方法工作正常。我正在使用弹簧靴和百里香

Question

我看到这个问题有很多问题，但没有任何帮助。我找不到解决方案，所以我正在分享我自己的代码并寻求帮助

控制器

1. 我用GetMapping（如图（来自Udemy的课程））和@DeleteMapping注释尝试了所有这些方法，但它们都没有工作......
2. 我还尝试添加 @RequestBody 注释，因为有些人对此错误的另一个问题发表了评论
3. 我在 application.properties 文件中添加了 spring.mvc.hiddenmethod.filter.enabled=true
4. 我尝试使用 delete 而不是 deleteById

    @RequestMapping(value="/deleteProperty/{idProperty}", method = {RequestMethod.DELETE, RequestMethod.GET)
        public String deleteProperty1(@PathVariable int idProperty) {
            propertyService.deleteById(idProperty);
            return "redirect:/admin/properties/allProperties";
        }

    @RequestMapping(value="/deleteProperty/{idProperty}", method = RequestMethod.DELETE)
    public String deleteProperty1(@PathVariable int idProperty) {
        propertyService.deleteById(idProperty);
        return "redirect:/admin/properties/allProperties";
    }

    @RequestMapping(value="/deleteProperty/{idProperty}", method = RequestMethod.DELETE)
    public String deleteProperty1(@PathVariable("idProperty") int idProperty) {
        propertyService.deleteById(idProperty);
        return "redirect:/admin/properties/allProperties";
    }

    @RequestMapping(value="/deleteProperty/{idProperty}", method = RequestMethod.DELETE)
    public void deleteProperty1(@PathVariable("idProperty") int idProperty) {
        propertyService.deleteById(idProperty);
    }

    @RequestMapping(value="/deleteProperty/{idProperty}", method = RequestMethod.DELETE)
    public String deleteProperty1(@RequesParam("idProperty") int idProperty) {
        propertyService.deleteById(idProperty);
        return "redirect:/admin/properties/allProperties";
    }

    @RequestMapping(value="/deleteProperty/", method = RequestMethod.DELETE)
    public String deleteProperty1(@RequesParam("idProperty") int idProperty) {
        propertyService.deleteById(idProperty);
        return "redirect:/admin/properties/allProperties";
    }

和更多...

我还是不明白怎么回事……

物业服务

@Service
public class PropertyServiceImpl implements IPropertyService {

    private IPropertyRepository propertyRepository;

    @Autowired
    public PropertyServiceImpl(IPropertyRepository thePropertyRepository) {
        propertyRepository = thePropertyRepository;
    }

属性服务接口

public interface IPropertyService {

    public Property findById(int theId);

    public void save(Property theProperty);

    public void deleteById(int theId);
