【问题描述】：
我正在尝试在 tomcat 服务器上实现 hazelcast 会话。
我在 tomcat7/lib 中放入了以下 jars：
hazelcast-tomcat8-sessionmanager-1.0.3.jar，
hazelcast-3.7.4.jar 和 hazelcast-client-3.7.4.jar。
在 tomcat8/conf/server.xml 我有：
<Listener className="com.hazelcast.session.ClientServerLifecycleListener" />
在tomcat8/conf/Catalina/localhost/app.xml中：
<Manager className="com.hazelcast.session.HazelcastSessionManager"
clientOnly="true"/>
似乎一切都开始正常，但当我访问应用程序时，我得到：

有人知道我做错了什么吗？谢谢
【问题讨论】：
-
显然
spring-security-web-xxx.jar在您的类路径/库中丢失。HazelcastSessionManager依赖于这个 jar。 -
您使用的是哪个 Tomcat 版本？ 8.0.39 还是 8.5.x？
-
该应用程序在没有 hazelcast 的情况下运行良好。这是一个在生产中运行了 5 年的应用程序，它具有所有依赖项。
-
tomcat-session推荐的tomcat，意思是8.0.36。
-
我无法重现您的问题。我刚刚注意到您在
tomcat8/conf/Catalina/localhost/app.xml中定义了<Manager>元素，但是hazelcast-tomcat-sessionmanager 页面（github.com/hazelcast/…）说它应该在$CATALINA_HOME$/conf/context.xml中定义。你能试试看它是否有效？
