使用Eclipse 3.1 WST编写Struts文件上传

可以在eclipse.org网站上下载WST with Eclipse3.1文件，该文件包括Eclipse3.1和WST以及它所需要的所有插件，基本上不用装其他插件了。

解包下载的文件后，建立新项目：Dynamic Web Project，这是需要配置调试用的Web服务器。我使用Tomcat 5.5，填写Tomcat 5.5的安装目录。

将Struts所需要的lib和Tld文件拷贝到WEB-INF目录

在WEB-INF/config目录里编写struts-config.xml如下

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

修改Web.xml将struts-config.xml填进去：

编写welcome.jsp和/pages/index.jsp文件

<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<logic:redirect forward="index"/>
<%--
Redirect default requests to Welcome global ActionForward.
By using a redirect, the user-agent will change address to match the path of our Welcome ActionForward.

--%>

index.jsp

<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

<html:html>
<Title>Upload Files</Title>
<body>
<html:form action="/protect/FileLoadAction.do" enctype="multipart/form-data">
<html:file property="theFile"/>
<html:submit/>
</html:form>
<bean:write name="UploadForm" property="theText"/>
</body>
</html:html>

注意红字属性必须填写，否则会出错。该<html:file>只能上传一个文件，如果要上传多个只能

<html:file property="theFile1"/>
<html:file property="theFile2"/>
<html:file property="theFile3"/>
不支持无定数文件上传。

编写Action和ActionForm

调试welcome.jsp。eclipse会启动Tomcat，在Console里打印启动log，其中会出现：web.xml cannot be found

这个错误可以忽略，不会有问题。

选择文件，点击index.jsp的submit。程序会跳转到FunctionImportAction 。如果在FunctionImportAction 设断点，可以停到断点出。非常方便。
