部署在外部Tomcat10上的Spring Boot 3会话集群错误

Question

我使用 Spring Boot 3.x 和外部 Tomcat 10。 在外部 Tomcat 上设置会话集群 如果我检查jsp页面，会话是共享的，但是 如果我使用 Spring Boot 服务检查相同的逻辑，则会话不会被共享。 如果我用jsp检查，它似乎是共享的，因此外部Tomcat之间的会话集群是不可能的。 看起来好像设置好了，但是为什么在Spring Boot中不能共享呢？ SpringBootServletInitializer已经实现了。

我正在 Windows 上本地使用两个不同的 Tomcat 端口进行测试。 Distributable="true" 在 Context 中设置。

@GetMapping("/session-test")
public String sessionTest(HttpSession session, Model model) {

   log.info("sessionTest  enter ");

    String sessionId = session.getId();
    Integer counter = (Integer) session.getAttribute("counter");
    if (counter == null) {
        counter = 1;
    } else {
        counter++;
    }
    session.setAttribute("counter", counter);

    model.addAttribute("sessionId", sessionId);
    model.addAttribute("counter", counter);

    return "web/sessionTest"; 
}

两个 Spring Boot 服务器希望共享它们的会话...

Answer 1

我是这样处理的...... 我不知道为什么我必须这样做。
