一:配置stuts2的运行环境,把以下的包放到WEB-INF/lib目录下
1,structs2-core-2.1.6.jar struts的核心库
2,xwork-2.1.2.jar webwork的核心库,需要它的支持
3, ognl-2.6.11.jar ognl表达式语言,struts2支持改EL表达式
4,freemarker-2.3.13.jar 表现层框架,定义了struts的可视组件主题
5,common-logging-1.0.4 .jar 日子管理
6,commons-fileupload-1.2.1.jar 文件上传于下载
二:struts2拦截用户请求,在web.xml里面配置
<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>
三:在src目录下配置struts.xml
内容如下
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<package name="default" namespace="/" extends="struts-default">
<default-action-ref name="index" />
<global-results>
<result name="error">/error.jsp</result>
</global-results>
<global-exception-mappings>
<exception-mapping exception="java.lang.Exception" result="error"/>
</global-exception-mappings>
<action name="index">
<result type="redirectAction">
<param name="actionName">HelloWorld</param>
<param name="namespace">/example</param>
</result>
</action>
</package>
<include file="example.xml"/>
<!-- Add packages here -->
</struts>
