Контроллеры Mapping

Question

Что не так? Мне написали два контроллера, но я не понимаю, что не так. Не знаю, как правильно настроить работу обоих контроллеров.

Cannot map 'bookController' bean method

package com.jackson;


@Controller
public class AuthorController {
    private AuthorService  authorService;

    @Autowired(required = true)
    @Qualifier(value = "authorService")
    public void setBookService(AuthorService authorService) {
        this.authorService = authorService;
    }

    @RequestMapping
            (value = "authors", method = RequestMethod.GET)
    public String listAuthors(Model model){
        model.addAttribute("author", new Author());
        model.addAttribute("listAuthors", this.authorService.list());

        return "authors";
    }

    @RequestMapping
            (value = "authors/add", method = RequestMethod.POST)
    public String addAuthor(@ModelAttribute("author") Author author){
        if(author.getId() == 0){
            this.authorService.addAuthor(author);
        }else {
            this.authorService.updateAuthor(author);
        }

        return "redirect:/authors";
    }


    @RequestMapping("/remove/{id}")
    public String removeAuthor(@PathVariable("id") int id){
        this.authorService.removeAuthor(id);

        return "redirect:/authors";
    }

    @RequestMapping("/edit/{id}")
    public String editAuthor(@PathVariable("id") int id, Model model){
        model.addAttribute("author", this.authorService.getAuthorById(id));
        model.addAttribute("listBooks", this.authorService.list());

        return "authors";
    }

    @RequestMapping("authordata/{id}")
    public String authorData(@PathVariable("id") int id, Model model){
        model.addAttribute("author", this.authorService.getAuthorById(id));

        return "authordata";
    }
}

На мой взгляд, весь код работает правильно, но все еще понимает, что не так

package com.jackson;        
@RestController
public class BookController {

    private BookService bookService;

    @Autowired(required = true)
    @Qualifier(value = "bookService")
    public void setBookService(BookService bookService) {
        this.bookService = bookService;
    }

    @RequestMapping(value = "books", method = RequestMethod.GET)
    public String listBooks(Model model){
        model.addAttribute("book", new Book());
        model.addAttribute("listBooks", this.bookService.listBooks());

        return "books";
    }

    @RequestMapping(value = "/books/add", method = RequestMethod.POST)
    public String addBook(@ModelAttribute("book") Book book){
        if(book.getId() == 0){
            this.bookService.addBook(book);
        }else {
            this.bookService.updateBook(book);
        }

        return "redirect:/books";
    }

    @RequestMapping("/remove/{id}")
    public String removeBook(@PathVariable("id") int id){
        this.bookService.removeBook(id);

        return "redirect:/books";
    }

    @RequestMapping("edit/{id}")
    public String editBook(@PathVariable("id") int id, Model model){
        model.addAttribute("book", this.bookService.getBookById(id));
        model.addAttribute("listBooks", this.bookService.listBooks());

        return "books";
    }

    @RequestMapping("bookdata/{id}")
    public String bookData(@PathVariable("id") int id, Model model){
        model.addAttribute("book", this.bookService.getBookById(id));

        return "bookdata";
    }
}

По моему мнению, весь код работает правильно, но все еще понимает, что не так

Answer 1

У ваших контроллеров есть методы сопоставления конфликтов.Не объявляйте один и тот же метод отображения запросов на разных контроллерах.

Answer 2

BookController должен иметь @Controller вместо @ RestController.
