JAVA springboot 大文件分断极速上传带上传进度条
- 效果图
项目部分架构为html+js+springboot+springMVC
因为没有考虑周到，前期开发有试用WEB文件简单上传，WEB文件多线程上传，sevlet文件分断上传+进度条等，虽都成功，但效果差强人意，直到遇见百度的webuploader，这里感谢百度的webuploader插件开源，虽然网上人员对它的吐槽也不少，哈哈。下面正式开始贴上代码
由于这个功能我觉得有必要分享给大家，因为这个功能是半年前写的，现在贴上，写的不好，希望大家少喷
这里主要注意的问题是，CSS或JS引入不生效的问题，可以将它们直接放在JS脚本或CSS脚 本前引入，或注意顺序问题。
这里感谢一个人提供的博客。这里深表感谢。我是把他的代码直接拿过来修改即用的。
webuploader API查阅官网
http://fex.baidu.com/webuploader/doc/index.html
一，首先前端需引入 代码片.
<!--引入CSS-->
<link rel="stylesheet" type="text/css" href="webuploader文件夹/webuploader.css">
<!--引入JS-->
<script type="text/javascript" src="webuploader文件夹/webuploader.js"></script>下载下面这个uploader.swf，并将它放入你的项目内，我放在了lib文件夹里
二，HTML代码
//文件选择按钮
<div id="uploader1" class="wu-example">
<div class="btns">
<span id="picker1"></span><span id="showtotalnumspan1"
style="display: none">您已选择<span
id="showfiletotalnum1"></span>个文件</span>
<br>
</div>
</div>
//进度条面板
<div id="thelist" class="uploader-list" style="display:none;"></div>
//文件上传事件按锯或清除按钮
<button id="ctlBtn" class="btn btn-default">开始上传</button>
<button id="" class="btn btn-default" onclick="clearFileData()">全部清空</button>三，JS部分（重点）
1.初始化Web Uploader
var $btn = $('#ctlBtn'); //此为文件上传按钮
var $thelist = $('#thelist'); //此为进度条
var chunkSize = 5 * 1024 * 1024; //此为文件流管道大小，即一次传输5MB字节，意思是分断大小
// HOOK 这个必须要再uploader实例化前面
WebUploader.Uploader.register({
'before-send-f ile': 'beforeSendFile',
'before-send': 'beforeSend'
}, {
beforeSendFile: function (file) {
console.log("beforeSendFile");
// Deferred对象在钩子回掉函数中经常要用到，用来处理需要等待的异步操作。
var task = new $.Deferred();
// 根据文件内容来查询MD5
uploader.md5File(file).progress(function (percentage) { // 及时显示进度
console.log('计算md5进度:', percentage);
getProgressBar(file, percentage, "MD5", "MD5");
}).then(function (val) { // 完成
console.log('md5 result:', val);
file.md5 = val;
// 模拟用户id
// file.uid = new Date().getTime() + "_" + Math.random() * 100;
file.uid = WebUploader.Base.guid();
// 进行md5判断
$.post("/fileupdown/checkFileMd5", {uid: file.uid, md5: file.md5},
function (data) {
console.log(data.status);
var status = data.status.value;
task.resolve();
if (status == 101) {
// 文件不存在，那就正常流程
} else if (status == 100) {
// 忽略上传过程，直接标识上传成功；
//uploader.skipFile(file);
//file.pass = true;
} else if (status == 102) {
// 部分已经上传到服务器了，但是差几个模块。
file.missChunks = data.data;
}
});
});
return $.when(task);
},
beforeSend: function (block) {
console.log("block")
var task = new $.Deferred();
var file = block.file;
var missChunks = file.missChunks;
var blockChunk = block.chunk;
console.log("当前分块：" + blockChunk);
console.log("missChunks:" + missChunks);
if (missChunks !== null && missChunks !== undefined && missChunks !== '') {
var flag = true;
for (var i = 0; i < missChunks.length; i++) {
if (blockChunk == missChunks[i]) {
console.log(file.name + ":" + blockChunk + ":还没上传，现在上传去吧。");
flag = false;
break;
}
}
if (flag) {
task.reject();
} else {
task.resolve();
}
} else {

}
return $.when(task);
