###### **1、eclipse，mysql，apache tomcat的安装和配置见前面几篇文章** ######

建一个Dynamic Web Project，取名叫OATest

###### **2、struts2配置** ######

下载struts2需要的的完整包，将其中的以下文件复制到eclipse的对应web工程的WebContent/WEB-INF/lib的lib目录下：

1）xwork-core-
                2）struts2-core-
                3）ognl-
                4）freemarker-
                5）commons-io-             6）commons-fileupload-             7）javassist-            8）commons-lang3-

###### **3、struts2修改web.xml** ######

修改web.xml增加过滤器filter，最终配置文件如下所示

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" 
    "http://struts.apache.org/dtds/struts-2.1.dtd">
    <struts>
    	<constant name="struts.i18n.encoding" value="GBK"></constant>
    	<package name="default" extends="struts-default">
    		<action name="loginAction" class="com.oa.action.LoginAction">
    			<result name="success">welcome.jsp</result>
    			<result name="error">err.jsp</result>
    		</action>
    	</package>
    </struts>

###### **4、定义表单的JSP页面** ######

<%@ page language="java" contentType="text/html; charset=GBK"
    	pageEncoding="utf-8"%>
    <%@ taglib prefix="c" uri="/struts-tags"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Insert title here</title>
    </head>
    <body>
    	<c:form action="loginAction">
    		<c:textarea name="username" key="username"></c:textarea>
    		<c:textarea name="password" key="password"></c:textarea>
    		<input type="submit" value="提交"/>
    	</c:form>
    </body>
    </html>

###### **5、定义拦截类com.oa.action.LoginAction** ######

**注意，包为com.oa.action**

package com.oa.action;
    
    import com.opensymphony.xwork2.ActionSupport;
    
    public class LoginAction extends ActionSupport {
    	private String username;
    	private String password;
    
    	public String execute() {
    		if (username.equals("a") && password.equals("a"))
    			return SUCCESS;
    		return ERROR;
    	}
    
    	public String getUsername() {
    		return username;
    	}
    
    	public void setUsername(String username) {
    		this.username = username;
    	}
    
    	public String getPassword() {
    		return password;
    	}
    
    	public void setPassword(String password) {
    		this.password = password;
    	}
    
    }
