webupload flash上传和整合springmvc

1.flash点击按钮没反应

最大的可能就是Uploader.swf路径不对，这个问题纠结了我半天

2. 整合springmvc，直接上代码

2.1 jsp页面引入相关js和css

2.2 jsp页面

	<div id="wrapper">
            <div id="container">
                <!--头部，相册选择和格式选择-->
                <div id="uploader">
                    <div class="queueList">
                        <div id="dndArea" class="placeholder">
                            <div id="filePicker"></div>
                            <p>或将照片拖到这里，单次最多可选300张</p>
                        </div>
                    </div>
                    <div class="statusBar" style="display:none;">
                        <div class="progress">
                            <span class="text">0%</span>
                            <span class="percentage"></span>
                        </div><div class="info"></div>
                        <div class="btns">
                            <div id="filePicker2"></div><div class="uploadBtn">开始上传</div>
                        </div>
                    </div>
                </div>
            </div>
        </div>
