Question

我正在编写一个简单的基于Spring的webapp，我在实现分页时遇到了问题。

适用于我的控制器方法：

var f=d=>
  d.forEach(k=>
    alert(k)
  );
let a=[1,2];
f(a);

观点：

@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;
}

据我设法将隐藏变量页传递给0.我不知道如何做其他页面。例如，点击

<#ftl encoding='UTF-8'>
<#import "/spring.ftl" as spring/>
<html>
<head>

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

        }
        #books{
            width: 70%;

        }

URI不会更改，只有页面参数为ceratin编号。感谢任何线索，也批评。

我只是通过重定向到另一个只显示确切页面的方法解决了我的问题。
