Struts2_三种传参数方法

Struts2_三种传参数方法


1、通过属性传参数(Attr)
UserAction.java
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;
    }
}


调用方法：
<a href="user/userAdd.action?name=Don&age=26">添加用户</a>
2、通过域模型传参数(Domain Model)
UserAction.java
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());
        // System.out.println("name:"+userDTO.getName());
        // System.out.println("age:"+userDTO.getAge());
        return SUCCESS;
    }


    // public void setUserDTO(UserDTO userDTO) {
    // this.userDTO = userDTO;
    // }
    //
    // public UserDTO getUserDTO() {
    // return userDTO;
    // }
}


User.java
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;
    }
}


UserDTO.java
package com.bebig.struts2.user.dto;
//数据传输对象
public class UserDTO {
    private String name;
    private String password;
    private String comfirmPassword;


    public String getPassword() {
        return password;
    }


    public void setPassword(String password) {
        this.password = password;
    }


    public String getComfirmPassword() {
        return comfirmPassword;
    }


    public void setComfirmPassword(String comfirmPassword) {
        this.comfirmPassword = comfirmPassword;
    }


    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：
<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
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;
    }


}


User.java
(源代码同上)
调用方法：
<p>使用ModelDriven传参数</p>

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