java uploadify 实现文件上传

1.web端使用uploadify插件 下载地址：http://www.uploadify.com/wp-content/uploads/files/uploadify.zip

web页面代码：

导入部分：

<script type="text/javascript" src="plugin/uploadify/jquery.uploadify-3.1.js"></script>
<script type="text/javascript" src="js/jquery-1.7.2.min.js"></script>
<link href="plugin/uploadify/uploadify.css" rel="stylesheet" type="text/css" />

js代码部分:

$function(){
$("#file_upload").uploadify({
'auto' 		: false,					// 关闭自动提交
	    'multi'          : false,
	    'queueSizeLimit' : 1,
		'fileTypeDesc' 	: '支持格式:zip',			// 文件类型
        'fileTypeExts' 	: '*.zip',	// 文件后缀
        'formData'      : {'paramname1':'paramvalue1','paramname...':'paramvalue...'},						// 提交时跟上去的参数
        'fileObjName'	: 'files',
        'fileSizeLimit' :'200MB',
		//'removeTimeout'	: 1,						// 从界面上移除的时间设置
		"buttonImage"	: path+'manage/plugin/uploadify/img/add_Flie.png',
'swf'			: path+'manage/plugin/uploadify/uploadify.swf',
'uploader'		: path+'jsonmanager/doArticle.action',
		'onQueueComplete' :  function(queueData) {
			$('#file_upload').uploadify('disable', false);
			$('.upload_btn').attr('disabled', false);
},
		'onUploadSuccess' : function(file, data, response) {
			
		},
		'onUploadStart'	: function(file) {
			$('#file_upload').uploadify('disable', true);
			$('.upload_btn').attr('disabled', true);
		}
});

}

页面调用部分：

<div style="width: 700px; height: auto; overflow-x: hidden;clear: both;" >
							<div style="overflow: hidden; float: left;width:200px;"><input type="file" name="files" id="file_upload" style="border: 0px;background-color: #fff;" /></div>
							<a href="javascript:void(0);" class="upload_btn" onclick="$('#file_upload').uploadify('upload', '*')"></a>
						</div>
						<div id="some_file_queue"></div>

请求的java代码：

提交时的参数

private List<File> files = new ArrayList<File>();
private List<String> filesFileName = new ArrayList<String>();
private List<String> filesContentType = new ArrayList<String>();

处理代码：

try {
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();
Long size = Long.parseLong(request.getHeader("Content-Length"));
StringBuffer ss = new StringBuffer();//存放返回的内容
for (int i = 0; i<files.size(); i++) {
String type = filesContentType.get(i);
String name = filesFileName.get(i);
int index = name.lastIndexOf(".");//原名称里倒 数第一个"."在哪里
String ext = name.substring(index+1); //取得后缀，及"."后面的字符
String tempFileName = name.substring(0, index);

byte data[] = new byte[1024 * 1024]; // 用于存放流数据
File file = new File(Utils.SPECIAL_ZIP_ADDRESS,tempFileName + "." + ext); // 新建文件 Utils.SPECIAL_ZIP_ADDRESS 服务器存放地址路径
//上传的文件存在时删除之前的专题文件

OutputStream fileOutputStream = null;
InputStream in = null;
try {
fileOutputStream = new FileOutputStream(file); // 创建文件流
in = new FileInputStream(files.get(i));
int bytesRead = 0;
while ((bytesRead = in.read(data)) > 0) {
fileOutputStream.write(data, 0, bytesRead); // 写入文件流
}
} catch (RuntimeException e) {
e.printStackTrace();
} finally{
if(fileOutputStream != null){
fileOutputStream.close();
fileOutputStream = null;
}
if(in != null){
in.close();
in = null;
}
}
}
}


response.setCharacterEncoding("utf-8");
response.getWriter().write(ss.toString());
response.getWriter().close();
} catch (Exception e) {
exceptionHandler(e);
}
