获取花括号的数据包括花括号
1 public static void main(String[] args) {
2 String fileUrl = "shncchdhd${whc$%^&edmcnvf123r}fdghjhjhhj#{bfghj}dcfhdvvfjhfjhfhj#{bfghj}";
3 Map<String, String> paramMap = new HashMap<>();
4 String regex = "(\\$|\\#)\\{[^{}]*\\})";//匹配的是#{xxx}或者${xxx}
5 Pattern p = Pattern.compile(regex);
6 Integer count = 1;
7 Matcher matcher = p.matcher(fileUrl);
8 while (matcher.find()) {
9 String searchStr = fileUrl.substring(matcher.start(), matcher.end());
10 if (StringUtils.isEmpty(paramMap.get(searchStr))) {
11 paramMap.put(searchStr, "${参数" + count++ + "}");
12 }
13 }
14 System.out.println(paramMap);
15 }
获取花括号内的数据 regex = (?<={)[^}]*(?=})，若解析字符串是：aaaa{b}，解析后是：b
