目前已测上传支持格式:{".rar", ".doc", ".docx", ".zip",
            ".pdf", ".txt", ".swf", ".xlsx", ".gif", ".png", ".jpg", ".jpeg",
            ".bmp", ".xls", ".mp4", ".flv", ".ppt", ".avi", ".mpg", ".wmv",
            ".3gp", ".mov", ".asf", ".asx", ".vob", ".wmv9", ".rm", ".rmvb"{

允许视频转码的格式:{ ".wmv9", ".rm", ".rmvb" }

如需上传多文件,后台需要使用MultipartFile[] 数组接收,然后for循环fileUploadTool.createFile,多文件上传未做测试,有需要的小伙伴自行测试。

1,前端代码

function testUploadVideo(){
	var fileObj = document.getElementById("file").files[0];  //获取文件对象
	var formFile = new FormData();
	formFile.append("param", "100");  //传入需要传的参数
	formFile.append("file", fileObj); // 加入文件对象
	var data = formFile;
	
	$.ajax({
		url : "../../lecture/uploadflv/uploadSave.action",
		type : "post",
		data : data,
		cache : false,// 上传文件无需缓存
		processData : false,// 用于对data参数进行序列化处理 这里必须false
		contentType : false, // 必须
		success : function(res) {
			alert("生成成功");
			alert(JSON.parse(res).result);  //接收前台返回json字符串
		},
		error : function() {
			alert("生成失败");
		}
	})
}
