使用HttpClient上傳大文件

我想用HttpClient將大型視頻文件（> = 1Gb）上載到servlet，但找不到任何實例。你能給我一些有用的代碼示例嗎？使用HttpClient上傳大文件

我想看到HttpClient和FileUpload演示代碼（作爲一個項目）。我可以使用FileUpload lib來下載大文件，這非常有趣嗎？

有趣的是，有上傳的約束這樣的小程序 - > servlet的

這裏的HttpClient和文件上傳的例子：

我不知道你的意思通過「真實」。這足夠真實，即使它不符合你的情況。

1GB？您可能會遇到文件大小限制問題。在本地嘗試，看看。如果失敗了，至少你會有一些真實的代碼和更確切的條件在這裏發佈。

感謝您對這樣一個快速回復我發現眼前這個例子 – user592704 2011-03-14 00:59:51

9-6。 HttpMultiPartFileUpload.java – user592704 2011-03-14 01:00:26

這很有趣，但我沒有看到任何提到的塊或緩衝區？所以HttpClient沒有HttpUrlConnection max_chunk_size限制？ – user592704 2011-03-14 01:03:13

我可以上傳大於200mb的大文件，請查看jsp下面的spring代碼。

Jsp code : 
<script src="../lib/app/configurator.data.ajax.js" type="text/javascript"></script> 
<script src="../lib/ui/jquery.fileupload.js"></script> 
<html> 

<script language="Javascript"> 
var varb = '';

var maxChunkSize = 30000000; //SET CHUNK SIZE HERE 
var your_global_var_for_form_submit = ''; 

var params = { 
     year: threeDSelectedYear, 
     series: threeDSelectedSeries 
}; 
/*File upload bind with form, 'fileupload' is my form id. As sumit triggers 
    for file ulaod will submit my form*/ 
/* replaceFileInput: true, */ 
$('#fileupload').fileupload({ 
maxChunkSize: maxChunkSize, 
url: efccustom.getEfcContext()+'upload/uploadZip?year='+threeDSelectedYear+'&series='+threeDSelectedSeries,    //URL WHERE FILE TO BE UPLOADED 
    error: function (jqXHR, textStatus, errorThrown) { 
    // Called for each failed chunk upload 
     $(".fileupload-loading").html(""); 
     $('.ANALYZE_DIALOG').dialog("close");  
    }, 

    success: function (data, textStatus, jqXHR) { 
    /*This event will be called on success of upload*/ 
    count = parseInt($('#counter').val()) + 1; 
    $('#counter').val(count); 

    $('#ttk').val(count); 
    data.ttk = 7; 
    console.log(" count ",count , data); 
    }, 

    submit: function (e, data) { 
    /*This event will be called on submit here i am 
        adding variable to form*/ 
    //console.log($('#zip_uploaded_file').val());  

    //console.log(data.originalFiles[0].name);    
    test = data.originalFiles[0]; 
    $('#fname').val(data.originalFiles[0].name); 
    $('#trequests').val(Math.ceil(data.originalFiles[0].size/maxChunkSize)); 
    $('#counter').val('1'); 
    }, 

    progress: function (e, data) { 
    /*PROGRESS BAR CODE WILL BE HERE */ 
     $(".fileupload-loading").html('<img src="../public/themeroller/images/throbber.gif" alt="Uploading Please Wait..." title="Uploading Please Wait...." />');  
    }, 

    add: function (e, data) {

    your_global_var_for_form_submit = data; 
    }, 

    done: function (e, data) {

      alert("file upload success ");

    }

    $('#button').click(function(){
