UploadForm上传一个form中的多个file

[苦苦的潜行者]

先上图


在一个form里面实现两个文件的不同时上传,两个上传互不干涉.

之前只有一个file 和submit,即Select Excel File那一行;现在我加上了下面的Feedback File 一行file和submit.
结果导致只能Feedback这个submit能够上传文件,Select那一行的submit一上传就出错,说是The input file was not found.
然后我后台输出Select一行的file.getFileName()为空.这是为什么呢!

上代码

这是form体

<html:form action="uploadAction.do?method=upFile"
			enctype="multipart/form-data">
			<c:choose>
				<c:when test="${zn == 'pilot'}">
					<input type="radio"  name="name" value="pilot" 
						checked="checked"  onclick="getZoneDate('pilot');"/>
					<font color="red">PRFQ1</font>
				</c:when>
				<c:otherwise>
					<input type="radio"  name="name" value="pilot" onclick="getZoneDate('pilot');"/>
					<font color="red">PRFQ1</font>
				</c:otherwise>
			</c:choose>
			<c:choose>
				<c:when test="${zn == 'week'}">
					<input type="radio"  name="name" value="week"
						checked="checked" onclick="getZoneDate('week');"/>
					<font color="red">PRFQ2</font>
				</c:when>
				<c:otherwise>
					<input type="radio"  name="name" value="week" onclick="getZoneDate('week');"/>
					<font color="red">PRFQ2</font>
				</c:otherwise>
			</c:choose>
			<br/>
				Select Excel File:<html:file property="theFile" />  
				<html:submit value="upload"/>  
			<br/>
			FeedBack    File:<html:file property="theFile" />  
			<html:submit value="upload" onclick="this.form.action='uploadAction.do?method=upFBFile'"/>  
		</html:form>

这是后台action过程

Select一行的submit

public ActionForward upFile(ActionMapping mapping, ActionForm form,
				HttpServletRequest request, HttpServletResponse response)
				throws Exception {
			String filePathName = "";
			if (form instanceof UploadForm) {
				String encoding = request.getCharacterEncoding();

				if ((encoding != null) && (encoding.equalsIgnoreCase("utf-8"))) {
					response.setContentType("text/html; charset=gb2312");
				}
				UploadForm theForm = (UploadForm) form;
				FormFile file = theForm.getTheFile();
				String contentType = file.getContentType();
				String zoneName = theForm.getName();
				String size = (file.getFileSize() + " bytes");
				String fileName = file.getFileName();
				// 
				System.out.println("fileName="+fileName);  //这里打印为"fileName=",明显没有值
				String timeStr = df.getTime("yyyyMMddhhmmss");
				try {
					InputStream stream = file.getInputStream();
					String filePath = request.getRealPath("/");
					ByteArrayOutputStream baos = new ByteArrayOutputStream();
					OutputStream bos = null;
					filePathName = filePath+ "files" + "\\"+ timeStr+file.getFileName();
					String pathName = request.getSession().getServletContext().getRealPath("/") + "files";
					File files= new File(pathName);
					if(files.exists()&&files.isDirectory()){
						bos = new FileOutputStream(filePath + "files"+ "\\"
								+ timeStr+file.getFileName());
						int bytesRead = 0;
						byte[] buffer = new byte[8192];
						while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
							bos.write(buffer, 0, bytesRead);
						}
					}else{
						boolean flag = files.mkdir();
						if(flag){
							bos = new FileOutputStream(filePath + "files"+ "\\"
									+ timeStr+file.getFileName());
							int bytesRead = 0;
							byte[] buffer = new byte[8192];
							while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
								bos.write(buffer, 0, bytesRead);
							}
						}
					}
					bos.close();
					stream.close();
				} catch (Exception e) {
				}
				request.setAttribute("contentType", contentType);
				request.setAttribute("size", size);
				request.setAttribute("fileName", fileName);
				request.setAttribute("filePathName", filePathName);
				request.setAttribute("zoneName", zoneName);
				return mapping.findForward("display");
			}
			return null;
		}

Feedback一行的submit

public ActionForward upFBFile(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		String filePathName = "";
		if (form instanceof UploadForm) {
			String encoding = request.getCharacterEncoding();

			if ((encoding != null) && (encoding.equalsIgnoreCase("utf-8"))) {
				response.setContentType("text/html; charset=gb2312");
			}
			UploadForm theForm = (UploadForm) form;
			FormFile file = theForm.getTheFile();
			String contentType = file.getContentType();
			String zoneName = theForm.getName();
			String size = (file.getFileSize() + " bytes");
			String fileName = file.getFileName();
			String timeStr = df.getTime("yyyyMMddhhmmss");
			try {
				InputStream stream = file.getInputStream();
				String filePath = request.getRealPath("/");
				ByteArrayOutputStream baos = new ByteArrayOutputStream();
				OutputStream bos = null;
				filePathName = filePath+ "files" + "\\"+ timeStr+file.getFileName();
				String pathName = request.getSession().getServletContext().getRealPath("/") + "files";
				File files= new File(pathName);
				if(files.exists()&&files.isDirectory()){
					bos = new FileOutputStream(filePath + "files"+ "\\"
							+ timeStr+file.getFileName());
					int bytesRead = 0;
					byte[] buffer = new byte[8192];
					while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
						bos.write(buffer, 0, bytesRead);
					}
				}else{
					boolean flag = files.mkdir();
					if(flag){
						bos = new FileOutputStream(filePath + "files"+ "\\"
								+ timeStr+file.getFileName());
						int bytesRead = 0;
						byte[] buffer = new byte[8192];
						while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
							bos.write(buffer, 0, bytesRead);
						}
					}
				}
				bos.close();
				stream.close();
			} catch (Exception e) {
			}
			request.setAttribute("contentType", contentType);
			request.setAttribute("size", size);
			request.setAttribute("fileName", fileName);
			request.setAttribute("filePathName", filePathName);
			request.setAttribute("zoneName", zoneName);
			return mapping.findForward("displayFB");
		}
		return null;
	}

这俩代码几乎似乎一样的,为什么会导致这样呢!

[softroad]

property="theFile" 两个名字 一样了。

[softroad]

Select Excel File:<html:file property="theFile" />
FeedBack File:<html:file property="theFile" />

楼主这么有2个submit

[安心逍遥]

页面上要设置一下

好像也不能用request获得

具体的忘了。楼主搜一下吧

祝你好运

我现在突然发现一种现象
就是我Select行的file没用!!
事实上这两个submit共用第二行的file
......
好惨!怎么办!
如果实在没有好的办法我只有共用file了

应该怎么修改呢?

4楼问题尚未解决,最近在看struts及struts标签,希望能从中获益,暂时共用一个file,希望以后问题解决再来分享答案.
