String url = "/users/{id}/books/{id_book}";
url = url.replaceAll("{\w*}", "\w*");
System.out.println("result url:" + url);
Trying to do a replace with regex, and returns me the following error:
Exception in thread "main" java.util.regex.PatternSyntaxException: Illegal repetition
{\w*}

Result I hope:
/users/\w*/books/\w*
