红帽全球峰会7.6. HTTP 会话 ID 更改
request.getSession （）.getId （） 调用返回的字符串，以获取分配给 HTTP 会话的唯一标识符，在 JBoss EAP 6.4 和 JBoss EAP 7 之间有所变化。
JBoss EAP 6.4 以 session-id.instance-id 格式返回会话 ID 和实例 ID。
JBoss EAP 7 和 EAP 8 仅返回会话 ID。
对于从 JBoss EAP 6 到 JBoss EAP 8 的一些升级，这个更改可能会造成无路由 Cookie 的问题。如果您的应用根据此方法调用的返回值重新创建 JSESSIONID cookies，您可能需要更新应用程序代码以提供所需的行为。
