jquery - Spring MVC ajax DELETE方法404错误

Question

请帮助我理解。一切都完成得很好，但是一种方法不起作用，我遇到了 404 错误我有几个请求

function deleteFunc(id) {
            $.ajax({
                dataType: "json",
                type: "DELETE",
                url: "/BookList.vw/" + id,
                async: true,
                success: function (response) {
                },
                error: function (e) {
                    alert("Book doesn't found");
                }
            });
        }

        function modifyFunc(id) {
            alert(id);
            $.ajax({
                dataType: "json",
                type: "PUT",
                url: "/EditBook.vw",
                data: id,
                success: function (response) {
                },
                error: function (e) {
                    alert('Server problems. You cannot modify this book.');
                }
            });
        }

Controller :

@Controller
@RequestMapping("/BookList.vw")
public class BookListController {

    @Autowired
    private IBookService bookService;

    public String getModelName() {
        return "BookList";
    }

    public BookListController() {
    }

    @RequestMapping(method = RequestMethod.GET)
    protected ModelAndView openMain(Model m) throws Exception {
        m.addAttribute("book", new Book());

        Map<String, Object> model = new HashMap<String, Object>();
        List<Book> books = bookService.listBooks();
        model.put("books", books);

        return new ModelAndView(getModelName(), "model", model);
    }

    @RequestMapping(method = RequestMethod.DELETE, value = "/{id}")
    public ModelAndView delete(@PathVariable int id) throws Exception {
        bookService.removeBook(id);
        return new ModelAndView(getModelName());
    }

    @RequestMapping(method = RequestMethod.POST)
    public ModelAndView search(@ModelAttribute Book b) throws Exception {
        List<Book> books = bookService.searchBook(b.getName().trim());
        Map<String, Object> model = new HashMap<String, Object>();
        model.put("books", books);

        return new ModelAndView("BookList", "model", model);
    }
}

搜索和主方法工作良好，但我不明白为什么 DELETE 方法出现错误，如下所示:

"NetworkError: 404 Not Found - http://localhost:8080/BookList.vw/2"

Answer 1

"NetworkError: 404 Not Found - http://localhost:8080/BookList.vw/2" 

我认为这个网址不正确，可能是这样的:

"NetworkError: 404 Not Found - http://localhost:8080/{ApplicationRoot}/BookList.vw/2"
