Jersey RESTful WebService框架学习(八)文件下载防乱码

最近在做下载时候  不同浏览器下载的文件一直出现乱码，不知道怎么设置文件的编码，百度许久，找到一个解决办法如下

/**
	 * 文件下载
	 * @param request
	 * @return
	 */
	@GET
	@Path("/d")
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
	public Response  download(@QueryParam("filemd5") String viFileMd5,@QueryParam("filename") String viFileName,@Context HttpServletResponse response) {
		File nFile = new File(WebConfig.MAIN_UPLOAD_TEMP_PATH + File.separator+ viFileMd5);
		// 如果文件不存在，提示404
		if (!nFile.exists()) {
			return Response.status(Response.Status.NOT_FOUND).build();
		}
		String nFileName = null;
		try {
			nFileName = URLEncoder.encode(viFileName, "UTF-8");
			response.setCharacterEncoding("UTF-8");
		} catch (UnsupportedEncodingException e1) {
			e1.printStackTrace();
		}
		return Response.ok(nFile).header("Content-disposition","attachment;filename=" + nFileName+";filename*=utf-8''"+nFileName).header("Cache-Control", "no-cache").build();
	}

设置header("Content-disposition","attachment;filename=" + nFileName+";filename*=utf-8''"+nFileName)即可
