struts2教程1
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
