1、直接把表單的參數寫在Controller相應的方法的形參中
|
1
2
3
4
5
6
|
@RequestMapping("/addUser1") public String addUser1(String userName,String password) { System.out.println("userName is:"+userName); System.out.println("password is:"+password); return "/user/success"; } |
2、通過HttpServletRequest接收
|

8
|
@RequestMapping("/addUser2") public String addUser2(HttpServletRequest request) { String userName = request.getParameter("userName"); String password = request.getParameter("password"); System.out.println("userName is:"+userName); System.out.println("password is:"+password); return "/user/success"; } |
3、通過一個bean來接收
1）建立一個和表單中參數對應的bean
|
1
2
|
public class User { private String userName; private String password; public String getUserName() { return userName; } //getter，setter方法。。. } |
2）用這個bean來封裝接收的參數
|
1
2
3
4
5
6
|
@RequestMapping("/addUser3")public String addUser3(User user) { System.out.println("userName is:"+user.getUserName()); System.out.println("password is:"+user.getPassword()); return "/user/success";} |
4、通過json數據接收

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Add User</title><script type="text/javascript" src="${pageContext.request.contextPath}/resource/script/jquery-1.9.1.min.js"></script><script type="text/javascript"> $(document).ready(function(){ $("#button_submit").click(function(){ var name = $("#userName").val(); var pass = $("#password").val(); var user = {userName:name,password:pass};//拼裝成json格式 $.ajax({ type:"POST", url:"${pageContext.request.contextPath}/user/addUser4", data:user, success:function(data){ alert("成功"); }, error:function(e) { alert("出錯："+e); } }); }); });</script></head><body> <form> <table> <tr> <td>賬號</td> <td> <input type="text" id="userName" name="userName"> </td> </tr> <tr> <td>密碼</td> <td> <input type="password" id="password" name="password"> </td> </tr> <tr> <td> </td> <td> <input type="button" id="button_submit" value="提交"> </td> </tr> </table> </form></body></html> |
依然可以使用bean來接收json數據

@RequestMapping("/addUser4") public String addUser4(User user) { System.out.println("userName is:"+user.getUserName()); System.out.println("password is:"+user.getPassword()); return "/user/success"; } |
5、使用jQuery的serializeArray() 方法序列化表單元素
如果表單元素很多，手工拼裝成json數據非常麻煩，可以使用jQuery提供的serializeArray()方法序列化表單元素，返回json數據結構數據。

@RequestMapping("/addUser5") public String addUser5(User user) { System.out.println("userName is:"+user.getUserName()); System.out.println("password is:"+user.getPassword()); return "/user/success"; } |
