struts-2.2.3 配置詳解
1、在WEB-INF下面的lib裡面新增下面的jar包
commons-fileupload-1.2.2
commons-io-2.0.1
commons-lang-2.5
commons-logging-1.1.1
freemarker-2.3.16
javassist-3.11.0.ga
ognl-3.0.1
struts2-core-2.2.3
xwork-core-2.2.3
2、WEB-INF下面的web.xml配置
其實只要在web.xml中新增一個filter就行了，web.xml配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- Struts2 Filter-->
<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>
</web-app>
3、src下面的struts.xml的配置
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="struts2" extends="struts-default" >
<action name="login" class="com.login.loginAction">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>
注意：
如果struts2版本是2.1以前
web.xml配置過濾器的時候應該是這樣：
<web-app>
<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>
</web-app>
如果struts2 版本是2.1以上
web.xml配置
<web-app>
<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>
</web-app>
