File file = new File("路径");InputStream is = null;try {is = new FileInputStream(file);} catch (FileNotFoundException e) {e.printStackTrace();}String filename = "";try {filename = new String( "你好百度.doc".getBytes("GBK"), "ISO8859-1" );} catch (UnsupportedEncodingException e2) {e2.printStackTrace();}//response.setHeader("Content-Type", "application/force-download;"); response.setHeader("Content-Disposition", "attachment" + ((!(Util.isNull(filename))) ? "; filename=" + filename : ""));try {Streams.copy(is, response.getOutputStream(), true);} catch (IOException e) {e.printStackTrace();} finally { try { is.close(); } catch (IOException e) { throw new RuntimeException(e); } }
