我有以下模板字符串:"Hello [Name] Please find attached [Invoice Number] which is due on [Due Date]".

我还有名称,发票号和截止日期的字符串变量 - 用变量替换模板中的标记的最佳方法是什么？

(请注意,如果变量恰好包含令牌,则不应替换它).

感谢@laginimaineb和@ alan-moore,这是我的解决方案:

public static String replaceTokens(String text, 
                                   Map<String, String> replacements) {
    Pattern pattern = Pattern.compile("\\[(.+?)\\]");
    Matcher matcher = pattern.matcher(text);
    StringBuffer buffer = new StringBuffer();

    while (matcher.find()) {
        String replacement = replacements.get(matcher.group(1));
        if (replacement != null) {
            // matcher.appendReplacement(buffer, replacement);
            // see comment 
            matcher.appendReplacement(buffer, "");
            buffer.append(replacement);
        }
    }
    matcher.appendTail(buffer);
    return buffer.toString();
}
