package qiniu;public class FileUtil {// 圖片允許的后綴擴展名public static String[] IMAGE_FILE_EXTD = new String[]{"png", "bmp", "jpg", "jpeg", "pdf"};/*** 獲取文件后綴* @param fileName* @return*/public static String getSuffix(String fileName) {int i = fileName.lastIndexOf(".");//如果沒有.證明該文件名不正確if (i < 0) {throw new RuntimeException("文件名不正確");};return fileName.substring(i + 1);}/*** 判斷文件后綴是否符合規定* @param fileName* @return*/public static boolean isSuffixAllow(String fileName) {String suffix = FileUtil.getSuffix(fileName);for (String s : IMAGE_FILE_EXTD) {if (s.equals(suffix)) return true;}return false;}
