java下载附件

java下载附件方法：

 

 	public void downloadAttachment(String fileName, String path, HttpServletResponse response){
		BufferedOutputStream bos = null;
		FileInputStream fis = null;
		
		if (fileName != null && !"".equals(fileName)) {
			try {	String disposition = "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8");//注意(1)

				response.setContentType("application/x-msdownload;charset=UTF-8");//注意(2)
				response.setHeader("Content-disposition", disposition);
				
				fis = new FileInputStream(path + fileName);
				bos = new BufferedOutputStream(response.getOutputStream());
				byte[] buffer = new byte[2048];
				while(fis.read(buffer) != -1){
					bos.write(buffer);
				}
			} catch (IOException e) {
				e.printStackTrace();
			}finally {
				if(fis != null){try {fis.close();} catch (IOException e) {}}
				if(bos != null){try {bos.close();} catch (IOException e) {}}
			}
		}
	}

 

尤其注意以上两个需要注意的地方，如果要下载的文件名不做URLEcode处理，项目部署到linux服务器上的话，下载提示框会显示文件名为乱码！！！！！！！！！！！！！！！！！！
