Action设置数据
第一种方式:属性驱动(FieldDriven)
A:基本数据类型
public class UserAction extends ActionSupport{
/**
* 基本数据类型
*/
private String userName;
private String password;
private User user = new User();
private UserService userService = new UserService();
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;
}
private static final long serialVersionUID = 1L;
public String execute() throws Exception{
user.setUsername(userName);
user.setPassword(password);
if(userService.login(user)){
return SUCCESS;
}else{
return ERROR;
}
}
}
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<form action="hello" method="post">
用户名:<input type="text" name="userName"><br/>
密码:<input type="text" name="password"></br>
<input type="submit" value="提交">
</form>
</body>
</html>
B:javaBean类型属性
public class UserAction2 extends ActionSupport{
/**
* javaBean类型属性
*/
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
private UserService userService = new UserService();
private static final long serialVersionUID = 1L;
public String execute() throws Exception{
if(userService.login(user)){
return SUCCESS;
}else{
return ERROR;
}
}
}
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<form action="user" method="post">
用户名:<input type="text" name="user.userName"><br/>
密码:<input type="text" name="user.password"></br>
<input type="submit" value="提交">
</form>
</body>
</html>
第二种方式:模型驱动
public class UserAction3 extends ActionSupport implements ModelDriven<User>{
/**
* 模型驱动(ModelDriven)
*/
private static final long serialVersionUID = 1L;
private User user = new User();
private UserService userService = new UserService();
@Override
public String execute() throws Exception{
System.out.println("执行了UserAction3的默认方法");
if(userService.login(user)){
return SUCCESS;
}else{
return ERROR;
}
}
@Override
public User getModel() {
// TODO Auto-generated method stub
return user;
}
}
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<form action="user3" method="post">
用户名:<input type="text" name="userName"><br/>
密码:<input type="text" name="password"></br>
<input type="submit" value="提交">
</form>
</body>
</html>
A:基本数据类型
public class UserAction extends ActionSupport{
/**

*/
private String userName;
private String password;
private User user = new User();
private UserService userService = new UserService();
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;
}
private static final long serialVersionUID = 1L;
public String execute() throws Exception{
user.setUsername(userName);
user.setPassword(password);
if(userService.login(user)){
return SUCCESS;
}else{
return ERROR;
}
}
}
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

用户名:<input type="text" name="userName"><br/>
密码:<input type="text" name="password"></br>
<input type="submit" value="提交">
</form>
</body>
</html>

public class UserAction2 extends ActionSupport{
/**

private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
private UserService userService = new UserService();
private static final long serialVersionUID = 1L;
public String execute() throws Exception{
if(userService.login(user)){
return SUCCESS;
}else{
return ERROR;
}
}
}
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<form action="user" method="post">
用户名:<input type="text" name="user.userName"><br/>
密码:<input type="text" name="user.password"></br>
<input type="submit" value="提交">

</body>
</html>

return SUCCESS;
}else{
return ERROR;
}
}
@Override
public User getModel() {
