Java正则表达式的问题

对于下面给定的字符串，如何提取出其中的变量。
变量用法：{$变量名}

如：{$LOAD_PATH}/61347d650c1a451e98b0fe8389b25f3c/{$TIMESTAMP}

应该识别出包含两个变量，分别是LOAD_PATH和TIMESTAMP。

[code="java"]String str = "{$LOAD_PATH}/61347d650c1a451e98b0fe8389b25f3c/{$TIMESTAMP}";
Pattern pattern = Pattern.compile("\{\$(\w+)\}");

Matcher matcher = pattern.matcher(str);
while (matcher.find()) {
System.out.println(matcher.group(1));
}[/code]

应该还要考虑到{}的情况，否则就会把路径里面有$的给解析了

是要截取两个字符之间的数据吗(?is)(?<={$LOAD_PATH}).*?(?={$TIMESTAMP} )

[code="java"]String str = "{$LOAD_PATH}/61347d650c1a451e98b0fe8389b25f3c/{$TIMESTAMP}";
Pattern pattern = Pattern.compile("\$(\w+)");

    Matcher matcher = pattern.matcher(str);
    while (matcher.find()) {
      System.out.println(matcher.group(1));
    }[/code]

({\$.*?})

lbfhappy 和 bylijinnan 2位仁兄已经给出了拿到变量名称 但是 $LOAD_PATH和$TIMESTAMP 一般我们在页面中是显示了值 所以应该是这样写成这样

String str = "{2222}/61347d650c1a451e98b0fe8389b25f3c/{333}";

Pattern pattern = Pattern.compile("\{(\w+)}");

    Matcher matcher = pattern.matcher(str);   
    while (matcher.find()) {   
        System.out.println(matcher.group(1));   
    } 

如果需求非要拿变量名 直接copy lbfhappy 和 bylijinnan 2位仁兄的代码即可！

[code="java"]
String s = "{$LOAD_PATH}/61347d650c1a451e98b0fe8389b25f3c/{$TIMESTAMP}";
Pattern p = Pattern.compile("(?<=\{\$)[A-Z_]+(?=\})");
Matcher m = p.matcher(s);
while (m.find()) {
System.out.println(m.group());
}
[/code]
