Answer 1

部分代码 采用apache fileUpload
 List upList = new ArrayList();
    try {
      DiskFileUpload fu = new DiskFileUpload();
      //设置最大上传尺寸
      fu.setSizeThreshold(1048576); //10M      List fileItems = fu.parseRequest(request);
      Iterator it = fileItems.iterator();
      String fileName = null;
      boolean flag = false;      while (it.hasNext()) {
        FileItem fi = (FileItem) it.next();
        long size = fi.getSize();
if(size > 10 * 1024 * 1024){
Map model = new HashMap();
model.put("error", "egis.support.taskprocess.error.A7005");
return new ModelAndView(ViewNames.UPLOAD_ATTACHMENTS_VIEW, model);
}
        
        //获取文件名和内容
        fileName = fi.getName();
        if(fileName == null || fileName.equals("")){
         continue;
        } else {
         flag = true;
        }        DevLog.debug("------->original file name is: " + fileName);
        int sindex = fileName.lastIndexOf('\\');
        if (sindex < 0) {
          sindex = fileName.lastIndexOf('/');
        }
        fileName = sindex < 0 ? fileName : fileName.substring(sindex + 1);        UploadAttachmentDTO dto = new UploadAttachmentDTO();
        dto.setBusinessActivityId(businessActivityId);        int dindex = fileName.lastIndexOf(".");
        dto.setAttachmentTypeCode(fileName.substring(dindex + 1).substring(0, 2));
        dto.setAttachmentVersionNo("1");
        dto.setBusinessActivityTypeCode(businessActivityTypeCode);
        dto.setAttachmentHeadline(fileName);
        dto.setAttachmentDescription(fileName);
        dto.setCreatedUser(userId);        String savePath = fileManager.uploadFile(fi.getInputStream(),
DirNameUtil.generateFilePath("", fileName, userId));
dto.setAttachmentPath(savePath);        upList.add(dto);
      }      if(!flag){
       throw new Exception("没有选择文件!");
      }

推荐你用jspsmartupload,非常好用的java上传组件！也非常成熟！网上资料很多，也很详细！

Answer 3

找了很久了，不知道再哪里有下载
它的网站已经不支持下载了。
也不知道如何在APACHE中配置，网上多数说在TOMCAT的配置
晕啊
