Struts2_三种传参数方法

1、通过属性传参数(Attr) UserAction.java

代码语言：javascript复制

package com.bebig.struts2.user.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {
    private String name;
    private int age;

    public String add() {
        System.out.println("name:" name);
        System.out.println("age:" age);
        return SUCCESS;
    }

    public int getAge() {
        return age;
    }

    public String getName() {
        return name;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public void setName(String name) {
        this.name = name;
    }
}

2、通过域模型传参数(Domain Model) UserAction.java

代码语言：javascript复制

package com.bebig.struts2.user.action;

import com.bebig.struts2.user.dto.UserDTO;
import com.bebig.struts2.user.model.User;
import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {
    // 通过域模型传参数
    private User user;

    // 通过数据传输对象传参数
    // private UserDTO userDTO;

    public User getUser() {
        return user;
    }

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

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

User.java

代码语言：javascript复制

package com.bebig.struts2.user.model;

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

    public int getAge() {
        return age;
    }

    public String getName() {
        return name;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public void setName(String name) {
        this.name = name;
    }
}

调用方法：

代码语言：javascript复制

<a href="user/userAdd.action?user.name=Don&user.age=26">添加用户</a>

3、通过模型驱动传参数(Model Driven) UserAction.java

代码语言：javascript复制

package com.bebig.struts2.user.action;

import com.bebig.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;
    }

}

代码语言：javascript复制
