Struts2系列笔记--入门与配置

MyEclipse下配置Struts2环境

导入Struts2依赖库jar包(核心有5个)：
commons-logging-1.0.4.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.11.1.jar
xwork-2.0.4.jar


配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
	<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>

配置struts.xml文件

<?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>
	<package name="default" extends="struts-default">
		<!-- 在这里添加Action定义 -->
	</package>
</struts>

编写Action类
要继承ActionSupport
复写execute() throws Exception

JSP页面

首先导入struts标签库：

<%@ taglib prefix=”s”  uri=”/struts-tags” %>

常用的几个struts-form 标签：

<s:form action=”*.action” method=”post”>
<s:textfield name=”username” label=”username” />
<s:password name=”password” label=”password” />
<s:submit name=”” value=”” />
<s:reset name=”” value=”” />

要求能熟练配置struts2环境，独立完成struts2登陆
