从java中的字符串中删除"$ {anything}"

Question

我想从字符串中删除$ {anything}或$ {somethingelse},但我找不到正则表达式.

我的实际代码

String url = http://test.com/index.jsp?profil=all&value=${value}
String regex = "\\$\\{*\\}";
url = url .replaceAll(regex, ""); // expect http://test.com/index.jsp?profil=all&value= 
//but it is http://test.com/index.jsp?profil=all&value=${value}

我确定解决方案是愚蠢的,但无法找到.

Answer 1

试试这个:

"\\$\\{.*?\\}"

本.*?场比赛后跟最短的字符串}.
