环境搭建
分为三步
- 引入关键包
- 加入struts的filter
- 配置struts的配置文件 struts.xml
准备 eclipse for javaEE
struts-2.3.16.3
首先是包

将上述包复制到该位置中,其他包按需添加，这里的包只是基本
完全的包是struts-2.3.16.3/lib/里面的包 不用全复制进去
之后配置web.xml
向web.xml中添加如下内容
<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>
配置struts2.xml
<?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>
这里是内容
