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
