Struts2--DomainModel接收参数---使用广泛!!!

1. JSP文件调用格式:

<a href="user/user!add?user.name=a&user.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;

public class UserAction extends ActionSupport {

private User user;
//private UserDTO userDTO;

public String add() {
　　System.out.println("name=" + user.getName());
　　System.out.println("age=" + user.getAge());
　　return SUCCESS;
}

public User getUser() {
　　return user;
}

public void setUser(User user) {
　　this.user = user;
}

}

Model:

package com.bjsxt.struts2.user.model;

public class User {
	private String name;
	private int age;
	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;
	}
}

衍伸: DTO:通过DTO new一个User对象出来,把值传过去: newUser(UserDTO dto)()

package com.bjsxt.struts2.user.dto;

public class UserDTO {
	private String name;
	private String password;
	private String confirmingPassword;
}
