1.从apache官网下载struts2（v2.2.1）的压缩文件，解压缩
2.打开myeclipse（v8.6），将struts2解压缩后lib下的ongl，strtus2-core，xwork-core，commons-logging，freemaker，javassist（该包需要另外下载，老版本里不需要）这六个必须包导入
在struts2（v2.2.3.1）除了上面包外还需导入commons-io,commons-lang,commons-fileupload
3.配置web.xml（WEB-INF下）
01 | <?xml version="1.0" encoding="UTF-8"?> |
02 | <web-app version="2.5" |
03 | xmlns="http://java.sun.com/xml/ns/javaee" |
04 | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" |
05 | xsi:schemaLocation="http://java.sun.com/xml/ns/javaee |
06 | http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> |
07 | <filter> |
08 | <filter-name>struts2</filter-name> |
09 | <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> |
10 | </filter> |
11 | |
12 | <filter-mapping> |
13 | <filter-name>struts2</filter-name> |
14 | <url-pattern>/*</url-pattern> |
15 | </filter-mapping> |
16 | |
17 | |
18 | <welcome-file-list> |
19 | <welcome-file>index.jsp</welcome-file> |
20 | </welcome-file-list> |
21 | </web-app> |
老版本中用的过滤器是Dispatch类
4.编写用户登录表单
01 | <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> |
02 | <% |
03 | String path = request.getContextPath(); |
04 | String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; |
05 | %> |
06 | |
07 | <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> |
08 | <html> |
09 | <head> |
10 | <base href="<%=basePath%>"> |
11 | |
12 | <title>My JSP 'index.jsp' starting page</title> |
13 | <meta http-equiv="pragma" content="no-cache"> |
14 | <meta http-equiv="cache-control" content="no-cache"> |
15 | <meta http-equiv="expires" content="0"> |
16 | <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> |
17 | <meta http-equiv="description" content="This is my page"> |
18 | <!-- |
19 | <link rel="stylesheet" type="text/css" href="styles.css"> |
20 | --> |
21 | </head> |
22 | |
23 | <body> |
24 | <form action="Login" method="post"> |
25 | |
26 | <Table> |
27 | <Tr> |
28 | <td>用户名:</Td> |
29 | <td><input type="text" name="username" /></Td> |
30 | </Tr> |
31 | <Tr> |
32 | <td>密码:</Td> |
33 | <td><input type="password" name="password" /></Td> |
34 | </Tr> |
35 | <Tr> |
36 | <td><input type="submit" name="submit" value="提交"/></Td> |
37 | <td><input type="reset" name="reset" value="重置"/></Td> |
38 | </Tr> |
39 | </Table> |
40 | |
41 | |
42 | </form> |
43 | </body> |
44 | </html> |
5.编写LoginAction.java
01 | package com.struts2.action; |
02 | |
03 | public class LoginAction { |
04 | private String username; |
05 | private String password; |
06 | |
07 | public String execute() throws Exception |
08 | { |
09 | if(this.getUsername().equals("tom")&&this.getPassword().equals("111111")){ |
10 | return "success"; |
11 | }else{ |
12 | return "error" ; |
13 | } |
14 | } |
15 | |
16 | public String getUsername() { |
17 | return username; |
18 | } |
19 | |
20 | public void setUsername(String username) { |
21 | this.username = username; |
22 | } |
23 | |
24 | public String getPassword() { |
25 | return password; |
26 | } |
27 | |
28 | public void setPassword(String password) { |
29 | this.password = password; |
30 | } |
31 | |
32 | |
33 | |
34 | } |
6.配置strtus.xml（src下）
01 | <?xml version="1.0" encoding="UTF-8" ?> |
02 | <!DOCTYPE struts PUBLIC |
03 | "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" |
04 | "http://struts.apache.org/dtds/struts-2.0.dtd"> |
05 | |
06 | <struts> |
07 | |
08 | <package name="strutsqs" extends="struts-default"> |
09 | <action name="Login" class="com.struts2.action.LoginAction"> |
10 | <result name="success">/welcome.jsp</result> |
11 | <result name="error">/error.jsp</result> |
12 | </action> |
13 | </package> |
14 | </struts> |
7.结果页面就一句话，就不写了
