未找到 Wildfly 17 分布式 Infinispan 缓存会话

Question

我正在研究使用分布式缓存为会话配置 wf 17，但我无法使其正常工作。这是一种分布式配置，我使用基本身份验证，当我们将帖子发送到 /j_security_check 时，它会发送到一个节点，而 /index.html 的 get 在身份验证成功完成后会发送到另一个节点。当请求到达第二个节点时，我有这个异常：

2019-10-16 17:17:39,901 TRACE [org.wildfly.clustering.web.infinispan] (default task-9) Session _ttZ3PQsisp4qCdTlkY512jYoG02S3DiYgpDUGjJ not found

我可以在发生 /j_security_check 帖子的另一台服务器上看到：

    contentLength=0  
       contentType=null  
            cookie=JSESSIONID=_ttZ3PQsisp4qCdTlkY512jYoG02S3DiYgpDUGjJ.staging-2:staging-2-wildfly; domain=null; path=/

我对 inifinispan 缓存的配置是：

                <cache-container name="web" default-cache="dist" module="org.wildfly.clustering.web.infinispan">
                    <transport lock-timeout="60000"/>
                    <distributed-cache name="dist" remote-timeout="17500" l1-lifespan="0" owners="2">
                        <locking acquire-timeout="60000" isolation="READ_COMMITTED"/>
                        <transaction locking="OPTIMISTIC" mode="BATCH"/>
                        <file-store/>
                    </distributed-cache>
                </cache-container>

只要会话被缓存在 infinispan 中，当请求最初到达第二台服务器时怎么会找不到它，但在尝试创建它时却抱怨它已经存在？

另外，我尝试配置 distributable-web:1.0 wf 子系统以使用上述缓存，但输出是相同的。不确定是否需要，如果我在 web.xml 中有标签，它将是相同的“默认”可分发网络子系统，对吗？

我注意到但我不明白的另一种情况：

这发生在同一个节点上，我收到了上述会话的响应，不久之后它无法找到会话，最终收到 j_security_check 的 404。

Answer 1

问题是重定向的请求在前一个请求完成提交之前试图读取会话。去掉事务并加锁标签即可解决。
