一.html中
    
    <tr>
        <td colspan="2" align="left"><label for="typeahead">主管部门（公章）：</label>
    		<form id="uploadForm1" enctype="multipart/form-data"  target="submitFrame">
    			<input type="file" name="upload" /> 										
    			<button id="btnUpload1" type="button" class='avoid-this'>上传</button>
    		</form>
    	</td>
    </tr>
    <link href="css/uploadify.css" rel="stylesheet">
    <script src="js/jqueryjs/jquery.uploadify-3.1.min.js"></script>
    
    二、js中
    
    		//上传
    $("#btnUpload1").bind( "click",function() {
    	$.ajax({
    	    url: '/xxxx/uploadOP.do',
    	    type: 'POST',
    	    cache: false,
    	    async :false,
    	    data: new FormData($('#uploadForm1')[0]),
    	    processData: false,
    	    contentType: false
    	}).done(function(res) {
    		// 保存成功后，初始化页面数据
    		if (res.done !== undefined) {
    			if(res.tb){
                    administrationsFile = res.tb ;
    				$("#administrations").attr("src", administrationsFile);
    
    			}
    		} 
    	}).fail(function(res) {
    		
    	});
    				
     });
     
     三、action中
     
    
    public class UploadOpAction extends ActionSupport {
    
    	/**
    	 * 生成项目内唯一版本ID
    	 */
    	private static final long serialVersionUID = -5210852842439224240L;
    	Logger log = Logger.getLogger(this.getClass());
    	
    
    	private Map<String, Object> dataMap;
    
    	public Map<String, Object> getDataMap() {
    		return dataMap;
    	}
    
    	private String businessId;
    	private String aa;
    	
    
    	// 封装上传文件域的属性
    	private File upload;
    	// 封装上传文件名的属性
    	private String uploadFileName;
    	// 封装上传文件类型的属性
    	private String uploadContentType;
    
    	
    	public File getUpload() {
    		return upload;
    	}
    	public void setUpload(File upload) {
    		this.upload = upload;
    	}
    	public String getUploadFileName() {
    		return uploadFileName;
    	}
    	public void setUploadFileName(String uploadFileName) {
    		this.uploadFileName = uploadFileName;
    	}
    	public String getUploadContentType() {
    		return uploadContentType;
    	}
    	public void setUploadContentType(String uploadContentType) {
    		this.uploadContentType = uploadContentType;
    	}
    	@Override
    	public String execute() throws Exception {
    		// 获取页面的请求信息
    		HttpServletRequest request = ServletActionContext.getRequest();
    		dataMap = new HashMap<String, Object>();
    		HttpSession session = request.getSession(false);
    		if (session == null) {
    			dataMap.put("error", "session不存在");
    			return SUCCESS;
    		}
    
    		businessId = (String) session.getAttribute("businessId");
    
    		String realPath = ServletActionContext.getServletContext().getRealPath("/uploadFiles");
    		String fileName=businessId+"."+uploadFileName;
    		if (upload != null) {
    			File savefile = new File(new File(realPath), fileName);
    			String path = savefile.getAbsolutePath();
    			int i = path.indexOf("CaiYiJia");
    			aa = path.substring(i+9,path.length());
    			dataMap.put("tb",aa);
    			dataMap.put("done","上传成功！");
    
    			if (!savefile.getParentFile().exists()) {
    				savefile.getParentFile().mkdirs();
    			}
    			FileUtils.copyFile(upload, savefile);
    		}
    
    		return SUCCESS;
    	}
    
    	public String errorUtils(Map<String, Object> dataMap, Exception e,
    			String value) {
    		dataMap.put("error", value);
    		e.printStackTrace();
    		return SUCCESS;
    	}
    	
    	
    }
