fancy公用上传下载

fancy公用上传下载

• 将fancy文件夹放在com.samsung.cs.quality.common.ui 下面的 webapp/csqCommon 的下面

• fileUpload.vm文件公用上传下载

  1.引用插件
  javascript <!--2019.1.15--> <link rel="stylesheet" type="text/css" href="/cs/csqCommon/fancy/style.css" /> <script type="text/javascript" src="/cs/csqCommon/fancy/mootools.js"></script> <script type="text/javascript" src="/cs/csqCommon/fancy/source/Fx.ProgressBar.js"></script> <script type="text/javascript" src="/cs/csqCommon/fancy/source/Swiff.Uploader.js"></script> <script type="text/javascript" src="/cs/csqCommon/fancy/source/FancyUpload3.Attach.js"></script>
  2.前台删除，新增，初始化的函数

        <script language="javascript">
  
      <!--2019.4.15-->
       function removeFiles(id){
  
        var val=document.getElementById("files").value;
        var v="";
        if(val!=''){
          var arr=val.split(",");
          if(arr.length==1){
             document.getElementById("files").value="";
          }else{
             for(var i=0;i<arr.length;i++){
                if(arr[i]!=id){
                  v=v+arr[i]+",";
                }
             }
             if(v!=""){
             //alert(v.substring(0,v.length-1));
               document.getElementById("files").value=v.substring(0,v.length-1);
             }
          }
        }
  
      }
  
      function addFiles(id){
         var val=document.getElementById("files").value;
        if(val==''){
           val=id;
        }else{
          val=val+","+id;
        }
        //alert(val);
        document.getElementById("files").value=val;
      }
  
  
  
  
  
  
    function initFile(apObj, filename, filesize, fileid, resourceId, mimeType){
         var file=new FancyUpload3.Attach.File(up,{id:1,size:filesize,name:filename,status:3,validationError:null});
        file.render();
        file.ui.element.highlight('#e6efc2');
        file.ui.element.getElement('.file-progress').destroy();
        file.ui.element.getElement('.file-cancel').destroy();
        var s=resourceId+"|"+filename+"|"+mimeType+"|"+fileid;
        new Element('span', {'class': 'file-removed', text: 'remove'}).removeEvents().addEvent('click', function() {
                    file.ui.element.destroy();
                    removeFiles(s);
                    //alert(s);
                    return false;
                }).inject(file.ui.size, 'after');
        file.ui.element.addEvent('dblclick',function(){
        var downUrl = "$contextPath/common/download/"+fileid;
        window.open(downUrl,"_blank","toolbar=0, status=0, scrollbars=yes, location=0, menubar=0, resizable=1")
        });     
        addFiles(s);
    }
    </script>

  3.html需要引用的宏，也是在fileupload.vm文件
  ```javascript

  macro (fileUploadSizablePanel $width $height $strID $actionFilePath $inputName $refType $refId $size)

  #if ($refId && \(refId != '') #set (\)fileObj = \(services.fileManager.findFileInfosByRef(\)refType, \(refId)) #else #set (\)fileObj = '')

  end

  
  $languageService.getMessage('seras.addFiles')
  

  end

  4.前台引用宏的地方html
  #fileUploadSizablePanel(670 60 'InnoAP' 'saveTemp.do' 'files' "$refType" $!document.id 10)
  5.点击add添加文件的时候，上传文件到服务器java
  //4.24增加
  @RequestMapping("/common/fileupload1.do")
  public void fileUpload1(HttpServletResponse response,HttpServletRequest request) throws IOException {
  MultipartHttpServletRequest req=(MultipartHttpServletRequest)request;
  Map map=req.getFileMap();
  Set keys=map.keySet();
  MultipartFile file=null;
  for(String key :keys){
  file=(MultipartFile)map.get(key);
  }
  String fileNamesStr=file.getOriginalFilename();
  ServletContext servletContext = req.getSession().getServletContext();
  String mimeType = servletContext.getMimeType(fileNamesStr);
  System.out.println(file.getSize());
  IResource resource= resourceManager.save(file.getInputStream(),file.getSize());
  System.out.println(resource.getId());
  System.out.println(fileNamesStr);
  System.out.println(mimeType);
  String s=resource.getId()+"|"+fileNamesStr+"|"+mimeType+"|"+null;
  String results="{status:1,id:'"+s+"'}";

    ViewUtils.jsonData(response, results.toString());

  }

  public IResource save(InputStream in, long totalTransferLen) throws IOException  {
  MD5 md5 = new MD5();
  File tmpFile = File.createTempFile("TMP", ".TMP", new File(fileUploadPath));
  try {
    byte []buf = new byte[bufferSize];
    int len = 0;
    long totalLen = 0;
    totalTransferLen = totalTransferLen == -1 ? Long.MAX_VALUE : totalTransferLen;
    String compression = this.compression;
    OutputStream tmpOut = null;
    long transferLen = totalTransferLen;
    try {
      while ((len=in.read(buf, 0, (int)(transferLen > buf.length ? buf.length : transferLen))) > 0) {
        md5.engineUpdate(buf, 0, len);
        
        if (tmpOut == null) {
          if (!canCompress(buf, len)) {
            compression = null;
          }
          tmpOut = compressedStream(new FileOutputStream(tmpFile), compression);
        }
        tmpOut.write(buf, 0, len);
        
        totalLen += len;
        transferLen = totalTransferLen - totalLen;
        if (transferLen > buf.length) transferLen = buf.length;
      }
    } finally {
      if (tmpOut != null) {
        tmpOut.close();
      }
    }
    byte[] digest = md5.engineDigest();
    return save(null, tmpFile, totalLen, digest, buf, compression);
  } finally {
    if (tmpFile.exists()) tmpFile.delete();
  }

  }

  private IResource save(InputStream in, File tmpFile, long totalLen, byte[] digest, byte[] buf, String compression)
    throws FileNotFoundException, IOException {
  String md5 = digestToId(digest);
  File file = find(md5, totalLen, compression);
  File parentFile = file.getParentFile();
  String id = file.getParentFile().getName() + file.getName();
  if (file.exists()) {
    if (totalLen > 0 && CompressionUtil.fileSize(file) != totalLen) {
      throw new IllegalStateException("For md5 hash " + md5 + 
        " the file " + file + " exists " +
        "but has conflicting size. The size must be " + totalLen + " bytes, " +
        "but is " + file.length() + " bytes.");
    }
  } else {
    if (!parentFile.exists()) parentFile.mkdirs();
    if (tmpFile != null) {
      if (tmpFile.renameTo(file)) {
        return new ResourceInfo(id, file);
      } else in = new FileInputStream(tmpFile);
    }
    FileOutputStream out = new FileOutputStream(file);
    try {
      transfer(in, out, buf);
    } finally {
      out.close();
    }
  }
  return new ResourceInfo(id, file);

  }
  6.前台提交javascript
  function fn_save(){

              document.frm.submit();
  
  }```

  7.提交之后后台处理
