public  String  openFile(@RequestParam( value="id",required=false)Integer id) { 
    		TiJian tijian = tijianService.selectByPrimaryKey(id);
    		String url;
    		String tips= "1"; 
    		//如果查询到文件路径了，有文件就打开，没有就返回2
    		if(tijian.getFujianid()!=null) { 
    			url = tijian.getFujianid();
    			try { 
    				File file = new File(url);// 创建文件对象
    				Desktop.getDesktop().open(file); // 启动已在本机桌面上注册的关联应用程序，打开文件文件file。
    			}catch(Exception e){ 
    				System.err.println(e);
    			}
    			tips = "2";
    		}
    		return tips;
    	}
