试了好久，当页面输入框有name属性的时候，后台action可以取到参数值；但是页面输入框只有id属性，而没有name属性的时候，后台怎么也取不到参数值，无论是从request对象取还是直接绑定action方法列表，都取不到，求解？
action代码：
[code="java"]
@RequestMapping(value="/showSelf/add", method={RequestMethod.GET, RequestMethod.POST})
public String addContent(Long id, HttpServletRequest request, HttpServletResponse response, ModelMap modelMap) throws Exception{
System.out.println("addContent!");
System.out.println("id is " + id);
String[] v = request.getParameterValues("id");
if(v != null){
System.out.println("getParameterValues is " + v[0]);
}
System.out.println("getParameter is " + request.getParameter("id"));
//HttpServletRequest request, HttpServletResponse response, ModelMap modelMap
// Enumeration pNames = request.getParameterNames();
// while(pNames.hasMoreElements()){
// System.out.println("paramName is " + pNames.nextElement());
// }
return "showSelf";
}
[/code]
页面代码：
[code="java"]
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

[/code]
以上代码action获取不到id为"id"的值，当页面中输入控件的id属性改为name时，后台可以取到
