utf-8字符集昵称含有特殊表情处理

使用以下两个处理方法即可

 /*** @param str 待转换字符串* @return 转换后字符串* @throws UnsupportedEncodingException exception* @Description 将字符串中的emoji表情转换成可以在utf-8字符集数据库中保存的格式*/public static String emojiConvert1(String str) throws UnsupportedEncodingException {String patternString = "([\\x{10000}-\\x{10ffff}\ud800-\udfff])";Pattern pattern = Pattern.compile(patternString);Matcher matcher = pattern.matcher(str);StringBuffer sb = new StringBuffer();while (matcher.find()) {try {matcher.appendReplacement(sb,"[["+ URLEncoder.encode(matcher.group(1),"UTF-8") + "]]");} catch (UnsupportedEncodingException e) {throw e;}}matcher.appendTail(sb);return sb.toString();}/*** @param str 转换后的字符串* @return 转换前的字符串* @throws UnsupportedEncodingException exception* @Description 还原utf8数据库中保存的含转换后emoji表情的字符串*/public static String emojiRecovery2(String str) throws UnsupportedEncodingException {String patternString = "\\[\\[(.*?)\\]\\]";Pattern pattern = Pattern.compile(patternString);Matcher matcher = pattern.matcher(str);StringBuffer sb = new StringBuffer();while (matcher.find()) {try {matcher.appendReplacement(sb,URLDecoder.decode(matcher.group(1), "UTF-8"));} catch (UnsupportedEncodingException e) {throw e;}}matcher.appendTail(sb);return sb.toString();}
