commons-uploadfile上传文件时无法得到返回的异常信息:
代码如下:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String saveDirectory = gbs.getBasicSetting("UploadFile.saveDirectory");
String tmpDirectory = gbs.getBasicSetting("UploadFile.tmpDirectory");
int maxPostSize = 1024 * 1024;
String FileName = null;
long FileSize = 0;
String strErr = null;
try {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
DiskFileUpload upload = new DiskFileUpload();
upload.setSizeThreshold(Integer.parseInt(gbs.getBasicSetting("UploadFile.sizeThreshold")));
upload.setSizeMax(maxPostSize);
upload.setRepositoryPath(tmpDirectory);
List items = null;
items = upload.parseRequest(request);
Iterator iter = items.iterator();
FileItem item = (FileItem) iter.next();
FileName = item.getName();
FileName = FileName.substring(FileName.lastIndexOf("\\") + 1);
FileName = FileName.substring(FileName.lastIndexOf("/") + 1);
FileSize = item.getSize();
if (FileSize == 0) {
strErr = "请选择上传文件！";
}
if (strErr != null) {
out.println("<script language=\"javascript\">alert('" + strErr + "');history.go(-1);</script>");
}
else {
out.println(FileSize);
File uploadedFile = new File(saveDirectory + FileName);
item.write(uploadedFile);
}
}
catch (Exception ex) {
System.out.println("错误");
}
}
限制上传文件大小后 上传超过小文件通过 但上传大文件 显示内容为空 如何才能捕捉到返回的异常?
------解决方法--------------------------------------------------------
我也加了上传的包，怎么找不到DiskFileUpload这个类呢

你上网查一下资料！应该是缺一个jar，是环境不对！在tomcat网站上有！我前天下了一个，配置上就好了！
