我正在编写一个简单的基于 spring 的 web 应用程序，在实现分页时遇到了问题。

适合我的 Controller 方法:

@RequestMapping(value = "/search", method = RequestMethod.GET)
public ModelAndView search(@ModelAttribute String ss, @RequestParam Integer page, HttpServletRequest request){

    String author = request.getParameter("author");
    String tittle = request.getParameter("tittle");
    String isbn = request.getParameter("ISBN");
    String language = request.getParameter("language");
    Integer pagesFrom;
    Integer pagesTo;
    Integer quantityFrom;
    Integer quantityTo;

    try{
        pagesFrom = Integer.parseInt(request.getParameter("numberOfPagesFrom"));
    } catch (NumberFormatException e){
        pagesFrom = Integer.valueOf(0);
    }
    try{
        pagesTo = Integer.parseInt(request.getParameter("numberOfPagesTo"));
    } catch (NumberFormatException e){
        pagesTo = Integer.MAX_VALUE;
    }

    try{
        quantityFrom = Integer.parseInt(request.getParameter("quantityFrom"));
    } catch (NumberFormatException e){
        quantityFrom = Integer.valueOf(0);
    }
    try{
        quantityTo = Integer.parseInt(request.getParameter("quantityTo"));
    } catch (NumberFormatException e){
        quantityTo = Integer.MAX_VALUE;
    }

    Predicate predicate = book.author.containsIgnoreCase(author)
            .and(book.tittle.containsIgnoreCase(tittle))
            .and(book.ISBN.contains(isbn))
            .and(book.language.contains(language))
            .and(book.numberOfPages.between(pagesFrom, pagesTo))
            .and(book.bookQuantity.quantity.between(quantityFrom, quantityTo));

    List<Book> books = bookRepository.findAll(predicate);

    PagedListHolder pagedListHolder = new PagedListHolder(bookRepository.findAll(predicate));
    pagedListHolder.setPage(page);
    pagedListHolder.setPageSize(5);
    ModelAndView mav = new ModelAndView("searchResult");
    mav.addObject("books", pagedListHolder.getPageList());

    return mav;
}

以及 View :

<#import "/spring.ftl" as spring/>
<html>
<head>

    <script>
        function goBack() {
            window.history.back();
        }

            text-align: center;
        }
        #books{

            margin-left: 15%;

            <td>${item.bookQuantity.quantity}</td>
        </tr>
        </#list>
    </#if>

    </tr>

    </tbody>

</table>

<div class="container-fluid">

    <nav>
        <ul class="pagination">
            <li class="page-item">
                <a href="#" class="page-link" aria-label="Previous">
                    <span aria-hidden="true">«</span>
                </a>
            </li>
            <li class="page-item"><a class="page-link" href="page=1">2</a></li>
            <li class="page-item"><a class="page-link" href="#">3</a></li>
            <li class="page-item"><a class="page-link" href="#">4</a></li>
            <li class="page-item"><a class="page-link" href="#">5</a></li>

            <li class="page-item">
                <a href="#" class="page-link" aria-label="Next">
                    <span aria-hidden="true">»</span>
                </a>
            </li>
        </ul>
    </nav>

</div>

<button id="goBackButton" type="button" class="btn btn-link" onclick="goBack()">Go Back</button>
</body>
</html>

据我设法将隐藏变量页面传递给0。我不知道如何做其他页面。例如点击 

<li class="page-item"><a class="page-link" href="#">3</a></li>

URI 没有改变，只是页面参数变成了某个号码。感谢任何线索，也包括批评。

最佳答案

我只是通过重定向到另一个仅显示确切页面的方法来解决我的问题。

关于java - Spring分页，如何修改Uri中的参数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40433110/
