    public static String[] string2Array(String string) {
        if (string != null && !string.isEmpty()) {
     
            if (string.startsWith(SPLIT_SYMBOL)) {
                string = string.substring(1);
            }
            if (string.endsWith(SPLIT_SYMBOL)) {
                string = string.substring(0, string.length() - 1);
