java - Shiro session 集群与 Hazelcast，而不是在 Web 上

Question

我编写了一个基于 Netty 的 REST 服务，该服务直接部署(即没有 Web/应用程序服务器)。对于 authn、authz 和 session 管理，我使用 Apache Shiro。现在我希望能够负载平衡此服务，而无需在负载平衡器上使用粘性 session ；我正在尝试使用进程内 Hazelcast 实例进行设置。

到目前为止，我已经成功让我的服务的两个实例在两台不同的计算机上运行，​​创建了一个具有两个成员的 Hazelcast 集群；但即便如此，如果我在一台机器上进行身份验证，另一台机器仍然无法识别该 session 。所以我认为我可能在 shiro.ini 和/或 hazelcast.xml 配置文件中犯了一个错误。

我本质上是使用这里的 HazelCastCacheManager 类 https://github.com/stormpath/shiro-hazelcast-web-sample/blob/master/src/main/java/com/stormpath/samples/shiro/hazelcast/cache/HazelcastCacheManager.java

这是我的 hazelcast.xml(我们的设置不允许多播，我必须直接指定机器 IP):

<hazelcast>
  <properties>
    <property name="hazelcast.logging.type">slf4j</property>
  </properties>

  <map name="shiro-activeSessionsCache">
    <async-backup-count>1</async-backup-count>
    <time-to-live-seconds>600</time-to-live-seconds>
  </map>

  <network>
    <join>
      <multicast enabled="false"></multicast>
      <tcp-ip enabled="true">
        <member>x.x.x.x:8050</member> <!-- server A -->
        <member>x.x.x.x:8050</member> <!-- server B -->
      </tcp-ip>
    </join>
    <interfaces enabled="true">
        <interface>x.x.x.*</interface>
    </interfaces>
    <port port-count="20" auto-increment="false">8050</port>    
  </network>

</hazelcast>

还有我的 shiro.ini 的一部分

sessionDAO = org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO
sessionManager = org.apache.shiro.session.mgt.DefaultSessionManager

sessionDAO.activeSessionsCacheName = shiro-activeSessionsCache
securityManager.sessionManager.sessionDAO = $sessionDAO

cacheManager = HazelcastCacheManager

securityManager.cacheManager = $cacheManager

sessionManager.globalSessionTimeout = 600000
sessionValidationScheduler = org.apache.shiro.session.mgt.ExecutorServiceSessionValidationScheduler
sessionValidationScheduler.interval = 600000
sessionManager.sessionValidationScheduler = $sessionValidationScheduler

securityManager.sessionManager=$sessionManager

我错过了什么？我如何指示 Shiro 在所有 Hazelcast 实例之间共享 session ？或者是我在 HazelcastCacheManager 类中的错误？

这是我启动两个服务时 Hazelcast 生成的日志:

这是启动的第一个服务:

Answer 1

我认为我的错误是在我的实际 Java 代码中，而不是在配置文件中:

在我所有的初始测试中，在单个服务器上运行该服务，我使用它来获取当前的 Shiro 用户:

Subject currentUser = SecurityUtils.getSubject();

但是，这样产生的 session key 对于一台服务器上的同一用户是相同的，但对于不同服务器上的同一用户来说是不同的； session key 用于标识缓存中的 session 。我最初希望能够不必在 REST 调用中传递 session key 。但是如果我显式传递 session key ，然后使用它来获取当前用户，那么 session 可以在不同的服务器中成功识别:

Subject currentUser = null;
if (parameters.containsKey("session")) {
    sId = parameters.get("session");
    currentUser = new Subject.Builder().sessionId(sId).buildSubject();
} else {
    currentUser = SecurityUtils.getSubject();
}

(在到达此代码片段之前，我使用 Map 来存储所有 URL 参数)

后续问题:是否可以在没有 cookie 的情况下共享 Shiro session ，或者以其他方式从客户端显式地将 session key 传递到服务器？
