5、struts2 action获取参数的三种方法
1：ModelDriven方式：

package com.domain;public class User {    private String name;    private String age;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getAge() {        return age;    }    public void setAge(String age) {        this.age = age;    }}
