Spring：在Tomcat群集故障转移中，HttpSession为SPRING_SECURITY_CONTEXT返回空对象

tomcat

我们有一个集群的tomcat环境，其中有两个节点（trunk-n1和trunk-n2），每个节点都有apache和tomcat实例，在以下情况下会出现问题

https://trunk/PP指向节点trunk-n1和trunk-n2节点的负载均衡器URL
，当两个节点都启动并且用户登录到应用程序时，如果用户位于N1上并且当我们将N1节点关闭时，负载分配器分配一个节点（假设为N1）。无缝重定向到N2，但有时用户会注销

以下是用于上述情况的无缝重定向的请求标头和Spring Security调试日志

某个节点关闭时，有人可以帮助我解决此随机用户注销问题吗？

一尘不染

Tomcat会话未复制，并且在节点之一发生故障时导致用户注销，配置hazelcast为实现会话复制，如下所示

步骤1：将以下依赖项添加到pom.xml

    <dependency>
        <groupId>com.hazelcast</groupId>
        <artifactId>hazelcast</artifactId>
        <version>3.6.2</version>
    </dependency>
    <dependency>
        <groupId>com.hazelcast</groupId>
        <artifactId>hazelcast-wm</artifactId>
        <version>3.6.2</version>
    </dependency>

第2步：在现有过滤器的顶部添加以下代码段，web.xml以便首先将请求转到hazelcast

<filter>
    <filter-name>hazelcast-filter</filter-name>
    <filter-class>com.hazelcast.web.spring.SpringAwareWebFilter</filter-class>
    <!--
        Name of the distributed map storing
        your web session objects
    -->
    <init-param>
        <param-name>map-name</param-name>
        <param-value>my-sessions</param-value>
    </init-param>
    <init-param>
        <param-name>config-location</param-name>
        <param-value>/WEB-INF/hazelcast.xml</param-value>
    </init-param>
    <init-param>
        <param-name>sticky-session</param-name>
        <param-value>true</param-value>
    </init-param>
    <!-- Are you debugging? Default is false.-->
    <init-param>
        <param-name>debug</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>hazelcast-filter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>REQUEST</dispatcher>
</filter-mapping>
<listener>
    <listener-class>com.hazelcast.web.SessionListener</listener-class>
</listener>

步骤3：建立hazelcast.xml如下

<hazelcast
    xsi:schemaLocation="http://www.hazelcast.com/schema/config http://www.hazelcast.com/schema/config/hazelcast-config-3.6.xsd"
    xmlns="http://www.hazelcast.com/schema/config"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</hazelcast>

第4步：初始化sessionRegistry您的beanapplicationContext.xml

<bean id="sessionRegistry" 
    class="org.springframework.security.core.session.SessionRegistryImpl" />

重新启动您的应用程序，并且会话复制可以在tomcat故障转移上运行
