读取项目包中的文件，读取项目包中文件,//第一种方法Strin

//第一种方法String fileUri = request.getRequestURI();String contextPath = request.getContextPath();if (!contextPath.endsWith( "/ ")) {    contextPath = contextPath + "/ ";}fileUri = fileUri.substring(contextPath.length(), fileUri.length());BufferedReader in = new BufferedReader(new InputStreamReader(getClass().getClassLoader().getResourceAsStream(fileUri)));PrintWriter out = response.getWriter();response.setContentType( "*; charset=GBK ");String line = null;while ((line = in.readLine()) != null) {    out.println(line);}in.close();out.close();//第二种方法URL resource = ActionForward.class.getResource("/vm/allpage/404.ftl");if(resource != null){    URLConnection urlConnection;    try {        urlConnection = resource.openConnection();        byte bytes[] = null;        java.io.InputStream is  = urlConnection.getInputStream();        bytes = IOUtils.toByteArray(is);        IOUtils.closeQuietly(is);        IOUtils.write(bytes, System.out);    } catch (IOException e) {        e.printStackTrace();    }}//该片段来自于http://byrx.net
