Tomcat 6.0大文件上傳（> 2 GB）
[英]Tomcat 6.0 Large File Upload (> 2 GB)
問題描述
我在使用大於2GB的文件上傳HTTP文件時遇到問題。 服務器和客戶端都是64位，因此從系統角度來看，必須沒有2GB的限制。 我做了以下事情：
- 在Apache LimitRequestBody = 0（ http://httpd.apache.org/docs/2.0/mod/core.html#LimitRequestBody ）
- 在Tomcat Connector maxPostSize = 0（ http://tomcat.apache.org/tomcat-5.5-doc/config/ajp.html ）
我正在使用apache commons文件上傳。 我還嘗試使用ServerFileUpload setMaxFileSize方法設置最大文件大小。
我能夠上傳小於2GB的文件（我成功嘗試了1.88GB文件）。 請指導我，我在這里錯過了什么？
更具體的說，ServletFileUpload.parseRequest方法在上傳大文件時返回0 FileItems
這是代碼片段：
if (isMultipartForm()) {
try {
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(SIZE_THRESHOLD);//SIZE_THRESHOLD = 4MB
ServletFileUpload upload = new ServletFileUpload(factory);
//upload.setFileSizeMax(3000000000L); Tried this too
upload.setProgressListener(progressListener);
items = upload.parseRequest(request);
if(items != null && items.size() == 0)
return new CommandResultSet(false, "NoItemsFoundInRequest");
return new CommandResultSet(true, "" + ( (items!=null) ? items.size() : ""));
} catch(FileUploadException e) {
e.printStackTrace();
System.out.println("Exception in MultipartFormManager. Can not parse request.");
return new CommandResultSet(false, e.getMessage());
}
}

如果您使用的是common-fileupload 1.1或者舊版本，則無法上傳（1.9888）~2GB。 這里的問題是這個jar正在調用一個名為getContentLength的方法，該方法是int類型，因此您的請求只能處理大小為Integer.MAX_VALUE的大小。 在像1.3這樣的common-fileupload的最新版本中，這已經解決了。 希望這可以幫助。

我當然可能出現新的錯誤，但我還沒有發現即使64位瀏覽器也能處理大於2GB的上傳。 問題不是服務器而是瀏覽器。 您會發現奇怪的是，大多數現代瀏覽器都會很樂意從標准服務器下載大於2GB的文件，無需特殊配置。

如果您希望上傳這些尺寸的文件，我不會依賴直接的瀏覽器上傳。 Java applet甚至可能是Flash文件（不確定，如果可能，不是Flash人員）將是我的建議，因此您可以將文件分成塊。 如果上傳中斷，您可以從上次停止的位置繼續。
