struts2工程创建步骤
1.添加JAR包
commons-logging-1.0.4.jar
freemarker-2.3.13.jar
ognl-2.6.11.jar
struts2-core-2.1.7.jar
xwork-core-2.1.4.jar
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
2.在web.xml配置文件中配置一个过滤器
<!-- 定义Struts 2的核心控制器：FilterDispatcher -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
3.创建一个Action
4.配置Action在struts.xml中
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
"http://struts.apache.org/dtds/struts-2.1.7.dtd">
<struts>
<package name="example" namespace="/example" extends="struts-default">
<action name="login" id="f1" action="<%=path %>/login.action" method="post">
?? ? ?<table border="0">
?? ? ? ?<tr>
?? ? ? ? ?<td>username:</td>
?? ? ? ? ?<td><input type="text" name="username" id="login"></td>
?? ? ? ?</tr>
?? ? ? ?<tr>
?? ? ? ? ?<td>Password:</td>
?? ? ? ? ?<td><input type="password" name="password" id="password"></td>
?? ? ? ?</tr>?
?? ? ? ?<tr>
?? ? ? ? ?<td colspan="2" align="center"><input type="submit" value="login"></td>
