Question

我有一个表单，用户可以在其中过滤待处理的事务。我想使用Spring的分页功能。只有在我不想过滤时（与getAll（）查询相同），这才能正常工作（如我所愿）。我的问题是，如果我将表单发布到控制器，它会搜索已过滤的事务，提供有关页数，总数的信息。但是，如果我单击分页按钮，它将转到签名为GET的方法（ URL例如是localhost ... / pending？page = 2＆amp; size = 20），我的表单使用默认值初始化。所以过滤器不起作用，只是分页。

@RequestMapping(value = "/pending", method = RequestMethod.GET, produces = "text/html")
public String getPendingTransactions(@ModelAttribute("pendingForm") PendingTransactionForm pendingForm, Model uiModel, HttpServletRequest httpServletRequest, Pageable pageable) {
    PageWrapper<Transaction> transactionItems = new PageWrapper<Transaction>(transactionService.searchPendingItemsByParams(pendingForm, pageable));
    uiModel.addAttribute("pendingForm", pendingForm);
    uiModel.addAttribute("transactionItems", transactionItems);
    uiModel.addAttribute("shoplist", transactionService.getShopListForNotFinishedItems());
    return "transaction/pendingtransactions";
}

@RequestMapping(value = "/pending", method = RequestMethod.POST)
public String processPendingTransactions(@ModelAttribute("pendingForm") PendingTransactionForm pendingForm, Model uiModel, HttpServletRequest httpServletRequest, Pageable pageable) {
    PageWrapper<Transaction> transactionItems = new PageWrapper<Transaction>(transactionService.searchPendingItemsByParams(pendingForm, pageable));
    uiModel.addAttribute("pendingForm", pendingForm);
    uiModel.addAttribute("transactionItems", transactionItems);
    uiModel.addAttribute("shoplist", transactionService.getShopListForNotFinishedItems());
    return "transaction/pendingtransactions";
}

有没有解决方案，如何一起实现过滤和分页？

更新：感谢Jose Luis Martin的回答，它确实有效！

@RequestMapping("/transactions")
@Controller
@SessionAttributes("pendingForm")
public class TransactionsController {

  @ModelAttribute("pendingForm")
  public PendingTransactionForm initializePendingForm() {
        return new PendingTransactionForm();
  }

  @RequestMapping(value = "/pending", method = {RequestMethod.POST, RequestMethod.GET}, produces = "text/html")
  public String getPendingTransactions(@ModelAttribute("pendingForm") PendingTransactionForm pendingForm, Model uiModel, Pageable pageable) {
       PageWrapper<Transaction> transactionItems = new PageWrapper<Transaction>(transactionService.searchPendingItemsByParams(pendingForm, pageable));
       uiModel.addAttribute("transactionItems", transactionItems);
       uiModel.addAttribute("shoplist", transactionService.getShopListForNotFinishedItems());
       return "transaction/pendingtransactions";
  }
}
