SSM框架-------------获取本地图片接口

最近项目遇到添加用户时，添加用户照片的需求。在展示列表的时候，需要从本地读取已存的图片，并在前端展示出来，下面直接给出接口：

 @RequestMapping("downloadFile.do")
		  public static void download(HttpServletRequest request,  
		      HttpServletResponse response, String storeName
		       ) throws Exception {  
		    
		    request.setCharacterEncoding("UTF-8");  
		    BufferedInputStream bis = null;  
		    BufferedOutputStream bos = null;  
		   			
		    //获取下载文件路径
		    String downLoadPath = "";
		 		
		 	downLoadPath = "D:\\upload\\image\\"+ storeName;  		  
		    //获取文件的长度  
		    long fileLength = new File(downLoadPath).length();  

		    //设置文件输出类型
		    response.setContentType("application/octet-stream");  
		    response.setHeader("Content-disposition", "attachment; filename="  
		        + new String(storeName.getBytes("utf-8"), "ISO8859-1")); 
		    //设置输出长度
		    response.setHeader("Content-Length", String.valueOf(fileLength));  
		    //获取输入流
		    bis = new BufferedInputStream(new FileInputStream(downLoadPath));  
		    //输出流
		    bos = new BufferedOutputStream(response.getOutputStream());  
		    byte[] buff = new byte[2048];  
		    int bytesRead;  
		    while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {  
		      bos.write(buff, 0, bytesRead);  
		    }  	
		    //关闭流
		    bis.close();  
		    bos.close();  
		  }
