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

QQ截图20140813193017.png

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
</struts>
