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>
