Question

我正在尝试将一些值从表单发送到响应主体，以便对这些值执行某些操作。但是这些值根本没有转发到该处理程序。我找不到理由。这可能是什么问题？

我的处理程序

    @RequestMapping(value="/redemptionRedirect1/{userId}", method=RequestMethod.GET)
     @ResponseBody 
     public Transaction submitRedemption(@PathVariable("userId") long userId,@RequestParam(value="amount") String amount1,@RequestParam("bankaccount") int bankaccount,@RequestParam("demataccount") int demataccount)
    {
        boolean flag;
        Double amount=Double.parseDouble(amount1);
        Transaction transaction=new Transaction();
        transaction.setBankAccount(transactionService.getBank(bankaccount));
        transaction.setDematAccount(transactionService.getDemat(demataccount));
        transaction.setTransactionAmount(amount);
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        String name = auth.getName();
        User user=userService.getUser(name);
        transaction.setUser(user);
        flag = transactionService.addRedemptionTransactions(transaction);
        return transaction;
    }

我的JSP

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form  action="redemptionRedirect1/${user.userId}.htm" method="get">
<table>
 <tr><td>Amount: </td><td><input id="amount" type="text" maxlength="5" value='<c:out     value="${amount}"/>' placeholder='<c:out value="${amount}"/>'/></td></tr>
 <tr><td>
 Bank Accounts: </td><td><select id="bankaccount" >
 <c:forEach items="${baccounts}" var="account">
  <option value='<c:out value="${account.accountNumber}"/>'>
 <c:out value="${account.name}"/>
 </option>
 </c:forEach>
 </select>
 </td></tr>
   <tr><td>Demat Account: </td><td><input  id="demataccount" type="text"  placeholder='<c:out value="${daccount.dematName}"/>' value='<c:out  value="${daccount.dematAccountNumber}"/>'/></td></tr>
 <tr><td><input type="submit" value="Confirm"/></td></tr>
 </table>
 </form>
 </body>
 </html>

表单通过每个输入的 name 属性自行序列化因此，首先您可以运行浏览器的开发人员工具功能，并检查值是否已添加到请求中（或仅适用于GET请求）检查提交后是否将值添加到URL。如果不是 - 为每个相应的输入添加name属性。

在使用rest服务时，表单无法将参数传递给requestparam
