First of all, REST and session identifiers don't sound well in the same sentence.
首先，REST 和会话标识符在同一个句子中听起来不太好。
The Sin RESTmeans statelessand not stateful. In REST applications, the session state must be managed by the client and not by the server. Consequently, there must not be any session identifiers.
在小号在REST手段无国籍，而不是状态。在 REST 应用程序中，会话状态必须由客户端管理，而不是由服务器管理。因此，不得有任何会话标识符。

I think you are looking for the following solution:
我认为您正在寻找以下解决方案：
Cookie cookie = requestContext.getCookies().get("JSESSIONID");
String value = cookie.getValue();
For more information about Cookie, have a look at the documentation.
