public class UserAction {    private String name;    private int     age;    public String add(){        System.out.println(name+age);        return "success";    }    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 class UserModelAction {    private User user;        public String add(){        System.out.println(user.getName()+user.getAge());        return "success";    }    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }        }
public class UserModelDrivenAction implements ModelDriven<User>{    private User user  = new User();;    public  String add(){        System.out.println("姓名"+user.getName()+"年龄:"+user.getAge());        return "success";    }    //使用 ModelDriven 将参数值存入对应的对象中，user 对象必须被初始化,在跳转的页面能够得到参数的值    @Override    public User getModel() {        // TODO Auto-generated method stub        return user;    }}
