Java正则表达式在大括号之间获取数据

您需要

( )

只是为了匹配并捕获大括号之间的内容。

String s  = "{one}{two}{three}";Pattern p = Pattern.compile("\{([^}]*)\}");Matcher m = p.matcher(s);while (m.find()) {  System.out.println(m.group(1));}

输出量

onetwothree

如果要三个特定的匹配组…

String s  = "{one}{two}{three}";Pattern p = Pattern.compile("\{([^}]*)\}\{([^}]*)\}\{([^}]*)\}");Matcher m = p.matcher(s);while (m.find()) {  System.out.println(m.group(1) + ", " + m.group(2) + ", " + m.group(3));}

输出量

one, two, three
