我正在做网上书店项目。我试图通过使用query作为参数通过postman发送get请求来找到一本书：http：//localhost：8080/api/v1/books/search？查询=托尔斯泰。403错误提示当我调试时，我意识到当我发送get请求时，我的控制器没有被调用。这是我的控制器：

@RestController
@RequiredArgsConstructor
@RequestMapping("/api/v1/books")
public class BookController {

    private final BookService bookService;
    @GetMapping("/search")
    public ResponseEntity<Set<Books>> searchBook(@RequestParam(value = "query",defaultValue = "a") String query){
        return ResponseEntity.ok(bookService.searchBooks(query));
    }
}

字符串
下面是我的服务为这个控制器：

@Service
@RequiredArgsConstructor
@Log4j2
public class BookServiceImpl implements BookService{

    private final BooksRepository booksRepository;
    @Override
    public Optional<Books> getById(Long id) {
        return booksRepository.findById(id);
    }

    @Override
    public Set<Books> searchBooks(String query) {
        List<Books> booksTitle = booksRepository.searchBookByTitle(query);
        List<Books> booksGenre = booksRepository.searchBookByGenre(query);
        List<Books> booksAuthor = booksRepository.searchByAuthor(query);
        Set<Books> books = Stream.of(booksTitle,booksGenre,booksAuthor).flatMap(Collection::stream).collect(Collectors.toSet());
        return books;
    }

这里是repository：

@Repository
public interface BooksRepository extends JpaRepository<Books,Long> {

    Optional<Books> findById(Long id);

    @Query(value = "SELECT b FROM books b WHERE b.title LIKE (%:query%)",nativeQuery = true)
    List<Books> searchBookByTitle(String query);

    @Query(value = "SELECT b FROM books b WHERE b.genre LIKE (%:query%)",nativeQuery = true)
    List<Books> searchBookByGenre(String query);
    @Query(value = "SELECT b FROM books b inner join books_and_authors bas on b.id = bas.book_id " +
            "inner join authors a on bas.author_id = a.id WHERE a.name LIKE (%:query%)",nativeQuery = true)
    List<Books> searchByAuthor(String query);
}
