1. 新建一个web project,
手动导入包:
D:\Java\jar\struts-2.3.24.1\apps\struts2-blank\WEB-INF\lib copy到 WEB-INF/lib下
D:\Java\jar\struts-2.3.24.1\apps\struts2-blank\WEB-INF\src\java下的struts.xml copy到src下进行修改:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.devMode" value="true" />
<package name="default" namespace="/" extends="struts-default">
<default-action-ref name="index" />
<global-results>
<result name="error">/WEB-INF/jsp/error.jsp</result>
</global-results>
<global-exception-mappings>
<exception-mapping exception="java.lang.Exception" result="error"/>
</global-exception-mappings>
<action name="login" class="net.nw.action.LoginAction">
<result name="login_success">login_success.jsp</result>
<result name="login_failure">login_failure.jsp</result>
</action>
</package>
</struts>
web.xml配置:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>Struts2_1900_OGNL</display-name>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>
Myeclipse配置的话:
右键项目->myeclipse->add struts...-> 下面选择*.action, *.do, /*, 选择最后一个
然后下一步选择core那个包, 会自动配置struts.xml和web.xml
2. WebRoot下新建一个login.jsp:
<%@ page language="java" import="java.util.*"%>
<%@ page contentType="text/html; charset=UTF-8" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP ‘login.jsp‘ starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<center>
<h1>系统登陆</h1>
<hr>
<form name="loginForm" action="<%=path%>/LoginServlet" method="post">
用户名: <input type="text" name="username"/><br>
密码 : <input type ="text" name="password"/><br>
<input type="submit" value="登陆"/><br>
</form>
</center>
</body>
</html>
3. 新建登录成功页面和失败页面 login_success.jsp, login_failure.jsp
<%@ page language="java" import="java.util.*"%>
<%@ page contentType="text/html; charset=UTF-8" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP ‘login.jsp‘ starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<center>
<h1>登陆成功</h1>
<hr>
</center>
</body>
</html>
<%@ page language="java" import="java.util.*"%>
<%@ page contentType="text/html; charset=UTF-8" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP ‘login.jsp‘ starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<center>
<h1>登陆失败</h1>
<a href="<%=path%>/login.jsp">返回</a>
<hr>
</center>
</body>
</html>
4. 视图层完毕, 下面是模型层: vo, dao,action
vo层: new package: net.nw.vo,
new class:Users.java:
package net.nw.vo;
public class Users {
private String username;
private String password;
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;
}
}
5. dao类:
new package: net.nw.dao,
dao类: UsersDAO.java:
package net.nw.dao;
import net.nw.vo.Users;
public class UsersDAO {
public boolean usersLogin(Users u){
if(u.getUsername().equals("admin")&&u.getPassword().equals("123456")){
return true;
}
else{
return false;
}
}
}
6. action
vo层: new package: net.nw.action
new class:LoginAction
package net.nw.action;
import net.nw.dao.UsersDAO;
import net.nw.vo.Users;
public class LoginAction {
public String username;
public String password;
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;
}
public String execute(){
Users u=new Users();
u.setUsername(this.getUsername());
u.setPassword(this.getPassword());
UsersDAO dao=new UsersDAO();
if(dao.usersLogin(u)){
return "login_success";
}
else{
return "login_failure";
}
}
}
配置struts如第一步.
