提取文本变量? 如 你好{name}? 提取name

正则提取文本

/**
 *  String pattern = "\\{[a-zA-Z0-9]*}";
 * @param regex
 * @param source
 * @return
 */
public static List<String> getMatcher(String regex, String source) {
    String result = "";
    //String pattern = "{[a-zA-Z0-9]*}";
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(source);
    List<String> list = new ArrayList<>();
    while (matcher.find()) {
        result = matcher.group(0);
        list.add(trimStr(result));
    }
    return list;
}
