我现在用的struts1框架,然后我做一个上传,用commons.fileupload做.
jsp文件:
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
我在Action中 的代码如下
DiskFileItemFactory factory=new DiskFileItemFactory();
String path=request.getSession().getServletContext().getRealPath("/upload");
System.out.println(path+"000");
factory.setRepository(new File(path));
factory.setSizeThreshold(1024*1024);
ProjectAccountsUploadForm pau=(ProjectAccountsUploadForm)form;
System.out.println("----"+pau.getFileItem());
ServletFileUpload upload=new ServletFileUpload(factory);
try
{
List list=upload.parseRequest(request);
for(FileItem item:list)
{
if(item.isFormField())
{
String name=item.getFieldName();
System.out.println(name+"111");
String value=item.getString("UTF-8");
request.setAttribute(name, value);
}
else
{
String name=item.getFieldName();
System.out.println(name+"222");
String value=item.getName();
System.out.println(value+"222");
int start=value.lastIndexOf("\");
String fileName=value.substring(start+1);
System.out.println(fileName+"222");
//request.setAttribute(name, fileName);
//item.write(new File(path,fileName));将档案写到上存目
}
}
}
catch (Exception e)
{
e.printStackTrace();
}
问1:就这么简单的一个FORM ,发过去就是list 是空的(list.isEmpty()=true) 这是为什么?
我的想法就是用struts的框架,但我不用他的标签,到action中后我用fileupload来上传,请指点!!
问2:有人说用struts的html:file,我在JSP中加入<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
然后用/html:file
这个页面一访问就报错,是什么原因!javax/xml/ws/WebServiceRef

Caused by: java.lang.NoClassDefFoundError: javax/xml/ws/WebServiceRef 应该是这个问题 ,但是我把其相应的jar加到工程里了(jaxws-api.jar),还是报这个错误.
[b]问题补充：[/b]
我现在的模式是用action,然后用的spring,将action交给了spring
http://blog.csdn.net/nalis/archive/2007/05/02/1594756.aspx
这里说不能配置actionForm,我把actionForm去掉了,还是不行,FileItem还是没有,我在想是不是我用了spring代理的问题呢 ?
最好是加个NAME属性，在解析的时候是根据NAME进行赋值的，万一不行就配置FormFile
这种方式进行上传应该没什么问题，唯一的缺点就是如果多上传需要配置多个FormFile
你可以去搜索一下，具体的使用方法，很简单
没了这个类
java.lang.NoClassDefFoundError: javax/xml/ws/WebServiceRef
你确认下你的jar是否少了
[code="java"]
//我的一个项目里面的代码给你贴出来
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List items = (List) upload.parseRequest(request); // 获得上传文件列表
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
File file = new File("保存的到的路径");
item.write(file); // 开始上传写入服务器
}
[/code]
Action 配置
[code="xml"]
[/code]
页面
给你加个name属性
lt0604 说的正是。把你代码调了一下，没加name属性跑不通，加了后正常了。
