我正在尝试通过 JMS/ActiveMQ 组件使用 Camel-Spring-remoting 集成 2 个 spring-mvc 应用程序。

我成功地能够从 App2 调用 App1 中的远程方法。

App1 和 App2 具有共享 Web 会话（使用 Spring-Session/Redis），其中包含 currentUserId 及其属性等数据。调用会话如下所示：

ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
HttpSession session = attributes.getRequest().getSession(false);
session.getSession().getAttribute("SYSTEM_USER_ACCOUNT");

因为远程方法调用是通过 JMS 发生的，所以 App1 无法识别先前经过身份验证的 HTTP 会话，并且我在 App1 中遇到了异常

org.apache.camel.RuntimeCamelException: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

这里的做法是什么？如何从 JMS 调用中访问 servlet 上下文和当前用户的 http-session？
