看代码：

add.jsp:

<form:form method="Post" action="/uploadDemo/admin/photo/add.spring" commandName="photoBean" id="photoBean_form" class="form-horizontal">
	<fieldset>
		<div class="control-group">
			<label class="control-label" for="focusedInput">NAME</label>
			<div class="controls">
				<form:input class="input-xlarge focused" id="name" path="name" type="text" />
			</div>
		 </div>
		<div class="control-group">
			<label class="control-label" for="focusedInput">IMAGE</label>
				<div class="controls">
					<form:hidden path="path"/>
					<input id="fileUpload" name="fileUpload"  multiple="true" /><img src="" id="imgId" style="display:none"/>
				</div>
		</div>
		<div class="form-actions">
			<button type="submit" class="btn btn-primary">Save changes</button>
		</div>
	</fieldset>
</form:form>

??
js:

<script type="text/javascript">   
var imgId = Math.uuid();
$(document).ready(function() {   

  $("#fileUpload").uploadify({   
    'swf'       : '../img/uploadify.swf',   
    'uploader'         : '/uploadDemo/scripts/uploadify?name=' + imgId,
    height        : 20,
    width         : 120,
    'queueSizeLimit' :1,  
    'fileTypeDesc'   : 'png或者jpg',  
    'fileTypeExts'   : '*.png;*.jpg', 
    'multi'          : false,  
    'buttonText'     : '上传',
    'wmode' : 'transparent',
    onUploadSuccess:function(file,data,response){
    	$("#path").val('/uploads/' + imgId + file.type);
    	showImg('/uploads/' + imgId + file.type);
    }

   });
  });
  
  function showImg(path) {
	  $("#imgId").attr('src', '/uploadDemo/' + path);
	  $("#imgId").show();
  }
	</script>
