java项目中怎么对特殊字符进行校验

public static boolean isChineseChar(char c) { try { return String.valueOf(c).getBytes("UTF-8").length > 1; } catch (UnsupportedEncodingException e) { e.printStackTrace(); return false; }}public static char validateLegalString(String content) { String illegal = "`~!#%^&*=+\\|{};:'\",<>/&#63;○●★☆☉♀♂※¤╬の〆"; char isLegalChar = 't'; L1: for (int i = 0; i < content.length(); i++) { for (int j = 0; j < illegal.length(); j++) {  if (content.charAt(i) == illegal.charAt(j)) {  isLegalChar = content.charAt(i);  break L1;  } } } return isLegalChar;}public static boolean isRightChar(char c) { return isChinese(c) || isWord(c);}public static boolean isWord(char c) { String regEx = "[\\w]"; Pattern p = Pattern.compile(regEx); Matcher m = p.matcher("" + c); return m.matches();}public static boolean isChinese(char c) { Character.UnicodeBlock ub = Character.UnicodeBlock.of(c); if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS  || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS  || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A  || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION  || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION  || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) { return true; } return false;}public static boolean checkNameChese(String name) { boolean res = true; char[] cTemp = name.toCharArray(); for (int i = 0; i < name.length(); i++) { if (!isChinese(cTemp[i])) {  res = false;  break; } } return res;}
