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;
@controller
public 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">

省份：<input type="text" name="address.province"><br>
<input type="submit" value="提交"><br>
</form>
