Question

我正在尝试删除该文件，如果不是电子表格，但在上传testFile.text时不断收到以下错误： ColdFusion无法删除文件D：\ ColdFusion10 \ cfusion \ runtime \ work \ Catalina \ localhost \ tmp \ testFile.text

我验证了它不是权限问题，因为如果我返回并执行代码以尝试再次删除该文件，它将起作用。

<cffile action="upload" destination="#dest#" filefield="xlsfile" result="upload" nameconflict="makeunique">


<cfif upload.fileWasSaved>
    <cfset theFile = dest & upload.serverFile>

    <cfif isSpreadsheetFile(theFile)>

        <cfscript>
            thisFile = theFile;
            fileRead = createObject("java", "java.io.FileInputStream");
            thisThread = CreateObject("java", "java.lang.Thread");
            loopCT = 1;
            while(1 EQ 1)
{
    try
    {
        fileRead.init(thisFile);
        break;
    }
    catch(any ecpt)
    {
        thisThread.sleep(1000);
    }
    incrementValue(loopCT);
    if(loopCT GT 60)
    {
        fileRead.close();
        return;
    }
}

loopCT = 1;
while(1 EQ 1)
{
    sizeA = fileRead.available();
    thisThread.sleep(1000);
    sizeB = fileRead.available();
    if(sizeA EQ sizeB)
    {
        thisThread.sleep(1000);
        sizeC = fileRead.available();
        if(sizeC EQ sizeB)
        {
            break;
        }

    incrementValue(loopCT);

    if(loopCT GT 60)
    {
        fileRead.close();
        return;

}
fileRead.close();

关于cfimage锁定文件并阻止删除，我遇到了完全相同的问题。我想出的解决方案如下。也许有人可以适应他们的情况：

<cflock name="[lockName]" timeout="5" >

   <cfcache action="flush">

    <!---[] Replace cfimage read function (CF BUG work around)  --->
   <cfscript>

      imageObj   = createObject( "java", "java.awt.Toolkit" );
      imagetools = imageObj.getDefaultToolkit();
      objImage   = imagetools.getImage( "#fullpath#" );
      <!---Whatever image I need from the image, or file...--->
      <!---such as ---- myImageStruct["width"] = objImage.getWidth();--->

      <!--- and then flush the object--->
      objImage.flush();

  </cfscript>

</cflock>

为什么我上传的文件被ColdFusion 10锁定？
