一   指定数据库：Mysql

　　database：oa

　　建库语句：create database oa default character set utf8

二   指定ide开发工具：MyEclipse

　　项目名称：新建web工程，名字为：OA，并设置项目工程编码：utf-8

　　环境所用主要技术框架：JUnit4，Struts2.3.15.1，Hibernate3.6，Spring2.5.6，jQuery，……

三　添加框架环境：

　　1.添加JUnit环境：

　　　　右击项目名称 --> Build Path --> Add Libraries --> JUnit，点击next，选择版本为JUnit 4，点击finish。完成JUnit环境添加。

　　2.添加Struts2.3.15.1环境：

　　　　添加jar包：

　　　　　　事先到官网下载好对应版本的项目环境，解压后打开进入apps文件夹里，用好压工具打开struts2-blank.war，点击WEB-INF，

　　　　　　将lib下面的jar包全部复制到我们OA项目的lib下面。

　　　　添加配置文件：

　　　　　　用好压工具打开struts2-blank.war，点击WEB-INF，将src --> java下面的struts.xml拷贝到我们OA项目的src下面。然后将

　　　　　　struts.xml里的内容修改为如下内容：

<span> 1</span> <span></span><span>xml version="1.0" encoding="UTF-8" </span><span>?></span>
<span> 2</span> <span><span>DOCTYPE struts PUBLIC
</span><span> 3</span> <span>    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
</span><span> 4</span> <span>    "http://struts.apache.org/dtds/struts-2.3.dtd"</span><span>></span>
<span> 5</span> 
<span> 6</span> <span><span>struts</span><span>></span>
<span> 7</span>     
<span> 8</span>     <span><!--</span><span> 设置为开发者模式 </span><span>--></span>
<span> 9</span>     <span><span>constant </span><span>name</span><span>="struts.devMode"</span><span> value</span><span>="true"</span> <span>/></span>
<span>10</span>     <span><!--</span><span> 把扩展名设置为.action，如name里的内容记不住，请在core包里的default.properties里面找 </span><span>--></span>
<span>11</span>     <span><span>constant </span><span>name</span><span>="struts.action.extension"</span><span> value</span><span>="action"</span> <span>/></span>
<span>12</span>     <span><!--</span><span> 把主题设置为simple，如name里的内容记不住，请在core包里的default.properties里面找 </span><span>--></span>
<span>13</span>     <span><span>constant </span><span>name</span><span>="struts.ui.theme"</span><span> value</span><span>="simple"</span> <span>/></span>
<span>14</span> 
<span>15</span>     <span><span>package </span><span>name</span><span>="default"</span><span> namespace</span><span>="/"</span><span> extends</span><span>="struts-default"</span><span>></span>
<span>16</span>         
<span>17</span>     <span></span><span>package</span><span>></span>
<span>18</span> 
<span>19</span>     <span><!--</span><span> Add packages here </span><span>--></span>
<span>20</span> 
<span>21</span> <span></span><span>struts</span><span>></span></span></span></span></span></span></span>

　　　　　　如果xml的代码不提示，在我们下载的项目包里面找，具体位置为：struts-2.3.15.1/src/core/src/main/resources/struts-2.3.dtd。

　　　　　　然后配置到myeclipse里面即可。

　　　　　　

　　　　　　用好压工具打开struts2-blank.war，点击WEB-INF，将web.xml里面的以下内容拷贝到我们的web.xml里面：

<span> 1</span> <span><span>filter</span><span>></span>
<span> 2</span> 
<span> 3</span>         <span><span>filter-name</span><span>></span>struts2<span></span><span>filter-name</span><span>></span>
<span> 4</span> 
<span> 5</span>         <span><span>filter-class</span><span>></span>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter<span></span><span>filter-class</span><span>></span>
<span> 6</span> 
<span> 7</span>     <span></span><span>filter</span><span>></span>
<span> 8</span> 
<span> 9</span>  
<span>10</span> 
<span>11</span>     <span><span>filter-mapping</span><span>></span>
<span>12</span> 
<span>13</span>         <span><span>filter-name</span><span>></span>struts2<span></span><span>filter-name</span><span>></span>
<span>14</span> 
<span>15</span>         <span><span>url-pattern</span><span>></span>/*<span></span><span>url-pattern</span><span>></span>
<span>16</span> 
<span>17</span>     <span></span><span>filter-mapping</span><span>></span></span></span></span></span></span></span>
