struts属性驱动与模型驱动
Struts2的属性驱动是使用Action的属性来封装来回请求参数和处理结果，即在jsp页面的每一个form中的name都对应在action中有一个属性与之对应。
Struts2的模型驱动的意思是使用单独的JavaBean来封装请求参数和处理结果。
一、属性驱动(1)
User JavaBean代码如下：
action代码如下：
在模型驱动中，action类需要继承ModelDriven接口，并必须要实现getModel()方法。

一、属性驱动(1)
User JavaBean代码如下：
package com.hsinghsu.testSSH.model;
public class User {
private Long id;
private String name;
private String pwd;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}action代码如下:
package com.hsinghsu.testSSH.action;
import org.springframework.beans.factory.annotation.Autowired;
import com.hsinghsu.testSSH.service.UserService;
public class LoginAction extends BaseAction {
/**
*
*/
private static final long serialVersionUID = -6144396976094110475L;
@Autowired
private UserService userService;
private String username;
private String password;
public String execute() throws Exception
{
System.out.println("username:"+username+" password:"+password);
if(userService.login(username,password))
{
return "success";
}
return "error";
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}struts.xml配置如下：
<action name="mylogin" class="com.hsinghsu.testSSH.action.LoginAction">
<result name="success">/jsp/welcome.jsp</result>
<result name="error">/jsp/login.jsp</result>
</action>login.jsp代码如下：
<%@ page language="java" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form action="mylogin.action" method="post">
Username:<input type="text" name="username"/><br/>
Password:<input type="password" name="password"/><br/>
<input type="submit" value="Submit"/>
</form>
</body>
</html>welcome.jsp代码如下：
<%@ page language="java" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="s" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>IWelcome</title> </head> <body> Welcome <s:property value="username"/> </body> </html>二、属性驱动(2)：
action代码如下：
package com.hsinghsu.testSSH.action;
import org.springframework.beans.factory.annotation.Autowired;
import com.hsinghsu.testSSH.model.User;
import com.hsinghsu.testSSH.service.UserService;
public class NoUserDrivenLoginAction extends BaseAction {
/**
*
*/
private static final long serialVersionUID = -3116586181830026380L;
private User user;
@Autowired
private UserService userService;
public String execute() throws Exception
{
System.out.println("username:"+user.getName()+" password:"+user.getPwd());
if(userService.login(user.getName(),user.getPwd()))
{
return "success";
}
return "error";
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}struts.xml配置如下：
<action name="noDrivenLogin" class="com.hsinghsu.testSSH.action.NoUserDrivenLoginAction">
<result name="success">/jsp/noDrivenWelcome.jsp</result>
<result name="error">/jsp/noDrivenLogin.jsp</result>
</action>noDrivenLogin.jsp代码如下：
<%@ page language="java" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form action="noDrivenLogin.action" method="post">
Username:<input type="text" name="user.name"/><br/>
Password:<input type="password" name="user.pwd"/><br/>
<input type="submit" value="Submit"/>
</form>
</body>
</html>noDrivenWelcome.jsp代码如下：
<%@ page language="java" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="s" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>IWelcome</title> </head> <body> Welcome <s:property value="user.name"/> </body> </html>三、模型驱动：
在模型驱动中，action类需要继承ModelDriven接口，并必须要实现getModel()方法。
action代码如下：
package com.hsinghsu.testSSH.action;
import org.springframework.beans.factory.annotation.Autowired;
import com.hsinghsu.testSSH.model.User;
import com.hsinghsu.testSSH.service.UserService;
import com.opensymphony.xwork2.ModelDriven;
public class UserDrivenLoginAction extends BaseAction implements ModelDriven<User>{
/**
*
*/
private static final long serialVersionUID = -3116586181830026380L;
private User user = new User();
@Autowired
private UserService userService;
public String execute() throws Exception
{
System.out.println("username:"+user.getName()+" password:"+user.getPwd());
if(userService.login(user.getName(),user.getPwd()))
{
return "success";
}
return "error";
}
@Override
public User getModel() {
return user;
}
}struts.xml配置如下：
<action name="drivenLogin" class="com.hsinghsu.testSSH.action.UserDrivenLoginAction">
<result name="success">/jsp/drivenWelcome.jsp</result>
<result name="error">/jsp/drivenLogin.jsp</result>
</action>drivenLogin.jsp代码如下：
<%@ page language="java" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<form action="drivenLogin.action" method="post">
Username:<input type="text" name="name"/><br/>
Password:<input type="password" name="pwd"/><br/>
<input type="submit" value="Submit"/>
</form>
</body>
</html>drivenWelcome.jsp代码如下：
<%@ page language="java" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="s" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>IWelcome</title> </head> <body> Welcome <s:property value="name"/> </body> </html>
