本篇文章主要介绍了SpringMVC接收页面表单参数的相关知识，具有很好的参考价值。下面跟着小编一起来看下吧
1、直接把表单的参数写在Controller相应的方法的形参中
@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、通过HttpServletRequest接收
@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、通过一个bean来接收
1）建立一个和表单中参数对应的bean
public class User { private String userName; private String password; public String getUserName() { return userName; } //getter，setter方法。。. }
2）用这个bean来封装接收的参数
@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、通过json数据接收
<%@ 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};//拼装成json格式 $.ajax({ type:"POST", url:"${pageContext.request.contextPath}/user/addUser4", data:user, success:function(data){ alert("成功"); }, error:function(e) { alert("出错："+e); } }); }); });</script></head><body> <form> <table> <tr> <td>账号</td> <td> <input type="text" id="userName" name="userName"> </td> </tr> <tr> <td>密码</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来接收json数据
@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() 方法序列化表单元素
如果表单元素很多，手工拼装成json数据非常麻烦，可以使用jQuery提供的serializeArray()方法序列化表单元素，返回json数据结构数据。
<%@ 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(){ //序列化表单元素，返回json数据 var params = $("#userForm").serializeArray(); //也可以把表单之外的元素按照name value的格式存进来 //params.push({name:"hello",value:"man"}); $.ajax({ type:"POST", url:"${pageContext.request.contextPath}/user/addUser5", data:params, success:function(data){ alert("成功"); }, error:function(e) { alert("出错："+e); } }); }); });</script></head><body> <form id="userForm"> <table> <tr> <td>账号</td> <td> <input type="text" id="userName" name="userName"> </td> </tr> <tr> <td>密码</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来接收json数据：
@RequestMapping("/addUser5") public String addUser5(User user) { System.out.println("userName is:"+user.getUserName()); System.out.println("password is:"+user.getPassword()); return "/user/success"; }
