y一个简单的工具类,附上:
/** * @param imgStr 图片的base64 * @param path 将要生成的地址 * @return */ public static boolean generateImage(String imgStr, String path) { if (imgStr == null) { return false; } BASE64Decoder decoder = new BASE64Decoder(); try { //解密 byte[] b = decoder.decodeBuffer(imgStr); //处理数据 for (int i = 0; i < b.length; ++i) { if (b[i] < 0) { b[i] += 256; } } OutputStream out = new FileOutputStream(path); out.write(b); out.flush(); out.close(); return true; } catch (IOException e) { e.printStackTrace(); return false; } }
