1.导包
将lib文件夹下的jar包导入到项目工程中
2.编写web.xml文件
web.xml
<display-name>goodsmessage</display-name>
<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>
<welcome-file-list>
<welcome-file>/foolish.jsp</welcome-file>
</welcome-file-list>
此段代码包含在<web-app></web-app>中。
3.在src下创建struts.xml文件
struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- 设置为true,当struts.xml文件更改时,不需重启tomcat -->
<constant name="struts.devMode" value="true"/>
<!--此处用来实现<input type="file">文件上传功能 -->
<constant name="struts.multipart.maxSize" value="102400000"/>
<include file="struts-default.xml"></include>
<package name="Login" extends="struts-default">
<action name="login" class="Login.AdminLoginAction">
<result name="loginfail">/loginerror.jsp</result>
<result name="loginsuccess">/newhome.lzw</result>
</action>
<action name="logout" class="Login.logout">
<result name="logout">/login.jsp</result>
</action>
</package>
</struts>
