【Struts2复习知识点九】ModelDriven接收参数

UserAction.java

import com.bjsxt.struts2.user.model.User;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class UserAction extends ActionSupport implements ModelDriven<User>{
    
    private User user = new User();
    
    public String add() {
        System.out.println("name=" + user.getName());
        System.out.println("age=" + user.getAge());
        return SUCCESS;
    }

    @Override
    public User getModel() {
        return user;
    }
    
}

访问：<a href="user/user!add?name=a&age=8">

此方法不常用。

实现ModelDriven接口后，后自动调用getModel方法  然后将值注入到dto中
