Struts2--ModelDriven接收参数
1. JSP文件调用格式:
<a href="user/user!add?name=a&age=8">添加用户</a>
2. struts.xml文件:
<package name="user" extends="struts-default" namespace="/user"> <action name="user" class="com.bjsxt.struts2.user.action.UserAction"> <result>/user_add_success.jsp</result> </action> </package>
3. action文件:和jsp传递过来的name和age一一对应传值进去
package com.bjsxt.struts2.user.action;
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(); //里面并没有name和age,而是通过getModel()返回的对象传值
public String add() {
System.out.println("name=" + user.getName());
System.out.println("age=" + user.getAge());
return SUCCESS;
}
@Override
public User getModel() {
return user;
}
}
