如何从多个服务器获取与 Spring Security 和 Spring Session 相同的会话

Question

对不起，我的英语还是不太好。 请多多包涵，希望你能理解我的问题..

---

我有两个网络服务器。 （每个 Web 应用程序都是一样的）

Web 服务器共享一个 redis 服务器。 我使用 Spring Security 和 Spring Session。 当我登录第一台服务器并访问第二台服务器时， 我想自动登录第二个服务器，但不是。

我猜，因为会话 id 与不同的服务器 ip 不同。

• 如何获取相同的会话 ID？

Answer 1

这似乎是一个老问题。但是，看起来可以实现想要的行为。查看http://docs.spring.io/spring-session/docs/current/reference/html5/guides/security.html了解更多详情

创建redis bean

<bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
    <property name="port" value="${app.redis.port}" />
    <property name="hostName" value="${app.redis.hostname}" />
</bean>

<context:annotation-config />
<bean
    class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"/>

上面将创建到Redis 服务器的连接，并将创建一个名为springSessionRepositoryFilter 的bean，它将替换常规的HttpSession 实现。

设置弹簧安全

可以通过使用org.springframework.security.web.FilterChainProxy 创建spring filter 即：

<b:bean id="springSecurityFilterChain" class="org.springframework.security.web.FilterChainProxy">
    <filter-chain-map request-matcher="ant">
         <filter-chain pattern="/somelocation/" filters="none" />
         <filter-chain pattern="/someotherlocation"
            filters="springSessionRepositoryFilter, somemorespring filters"/>
    </filter-chain-map>
</b:bean>

注意：spring security 的过滤器顺序很重要，不在此答案中。但是为了能够使用spring Session 和redis，第一个过滤器是springSessionRepositoryFilter。更多信息请访问http://docs.spring.io/spring-security/site/docs/3.0.x/reference/security-filter-chain.html

设置 Http 会话

编辑web.xml

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-  class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
 <filter-mapping> 
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

这将允许tomcat 在任何过滤器之前使用springSecurityFilterChain，因此它将允许springSessionRepositoryFilter 成为第一个过滤器。这将导致Spring session 魔法从redis db 中获取session

使用Spring session + spring security 不使用custom spring filters 可以在http://www.jayway.com/2015/05/31/scaling-out-with-spring-session/ 找到
