如何处理没有绑定对象的多行窗体在春天MVC

Question

我不知道要完美地构造我的问题，但我试图从HTML多行窗体中获取数据，我不想使用绑定对象和我不想在我的请求处理方法上有很多@RequestParam参数。我想表单提交返回一个int数组，但我得到以下错误HTTP Status 400 - Required int[] parameter 'department' is not present。我试着写形式以同样的方式人会做在PHP这样的：

<form action="processForm" method="POST"> 
<select name="department[]"> 
    <option value="NONE">---SELECT---</option> 
    <c:forEach items="${departments}" var="department"> 
    <option value="${department.getId()}">${department.getName()}</option> 
    </c:forEach> 
</select> 
<select name="department[]"> 
    <option value="NONE">---SELECT---</option> 
    <c:forEach items="${departments}" var="department"> 
    <option value="${department.getId()}">${department.getName()}</option> 
    </c:forEach> 
</select> 
<select name="department[]"> 
    <option value="NONE">---SELECT---</option> 
    <c:forEach items="${departments}" var="department"> 
    <option value="${department.getId()}">${department.getName()}</option> 
    </c:forEach> 
</select> 
<select name="department[]"> 
    <option value="NONE">---SELECT---</option> 
    <c:forEach items="${departments}" var="department"> 
    <option value="${department.getId()}">${department.getName()}</option> 
    </c:forEach> 
</select> 
</form> 

我控制器请求映射方法有提前如下

@Request(value = "/form",nethod = RequestMethod.GET) 
public String renderForm(){ 
    return "form" 
} 

@Request(value = "processForm", method = RequestMethod.POST) 
public String processForm(@RequestParam("department") int [] department){ 
    for (int i=0;i<department.lenth;i++){ 
     System.out.println(department[i]); 
    } 
} 

感谢你。

更改@RequestParam到@RequestParam("department[]")

@Request(value = "processForm", method = RequestMethod.POST) 
public String processForm(@RequestParam("department[]") int [] department){ 
    for (int i=0;i<department.lenth;i++){ 
     System.out.println(department[i]); 
    } 
}
