springmvc可以通过requestparam注解来映射获得参数，具体用法如下：
例子：
配置过程省略
1.新建controller类

package com.loger.controller;import org.springframework.stereotype.controller;import org.springframework.web.bind.annotation.requestmapping;@controllerpublic class requestparam { public static final string success = "success"; @requestmapping(value="/requestparam") public string requestparam(@org.springframework.web.bind.annotation. requestparam(value="username") string un, @org.springframework.web.bind.annotation.requestparam(value="age") integer age){ system.out.println(un + " " + age); return success; }} |
2.index.jsp
运行结果：
补充：如果表单名跟方法的参数名一致的话，无需再用@requestparam注解来映射。
如改为
@requestmapping(value="/requestparam")
public string requestparam(string username,integer age)即可！
用类作为参数，且包含级联属性的参数获取方法：
1.新建adress类

package com.loger.bean;public class address { private string province; private string city; public string getprovince() { return province; } public void setprovince(string province) { this.province = province; } public string getcity() { return city; } public void setcity(string city) { this.city = city; } @override public string tostring() { return "address [province=" + province + ", city=" + city + "]"; } } |
2.新建user类

package com.loger.bean;public class user { private string name; private int age; private address address; public string getname() { return name; } public void setname(string name) { this.name = name; } public int getage() { return age; } public void setage(int age) { this.age = age; } public address getaddress() { return address; } public void setaddress(address address) { this.address = address; } @override public string tostring() { return "user [name=" + name + ", age=" + age + ", address=" + address + "]"; } } |
3.controller
4.表单
user有级联属性address，表单传入的参数是address.city address.province

<form action="pojoparam"> 姓名：<input type="text" name="name"><br> 年龄：<input type="text" name="age"><br> 城市：<input type="text" name="address.city"><br> 省份：<input type="text" name="address.province"><br> <input type="submit" value="提交"><br> </form> |
运行结果：
