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：
