Question

所以我在Heroku上部署了我的Spring应用程序，有2个节点，我注意到如果我在购物篮中添加产品并开始刷新购物车页面，有时我会看到产品，有时产品不在那里。所以我想也许每次请求都会遇到不同的节点。

在春季会话网站上，我可以看到This can make clustering much easier. This is nice because the clustering setup is done in a vendor neutral way. Furthermore, in some environments (i.e. PaaS solutions) developers cannot modify the cluster settings easily.但我找不到如何使用spring-session进行粘性会话的设置。我的设置只是框中的一个：

@Bean(name = { "defaultRedisSessionRepository", "sessionRepository" })
@ConditionalOnProperty(name = { "nemesis.platform.redis.url" })
public SessionRepository defaultRedisSessionRepository(RedisTemplate<String,ExpiringSession> redisTemplate) throws Exception {
    return new RedisOperationsSessionRepository(redisTemplate);
}

然后在我的MVC配置中：

@Bean(name = {"defaultSessionFilter", "sessionFilter"})
public Filter sessionFilter() {
    CompositeFilter compositeFilter = new CompositeFilter();
    compositeFilter.setFilters(Arrays.asList(new SessionRepositoryFilter(applicationContext.getBean("sessionRepository", SessionRepository.class)), applicationContext.getBean(UrlEncoderFilter.NAME, UrlEncoderFilter.class)));

    return compositeFilter;
}

然后在我的WebApplicationInitializer：

    final FilterRegistration sessionFilterChainReg = servletContext.addFilter("sessionFilter", DelegatingFilterProxy.class);
    sessionFilterChainReg.addMappingForServletNames(EnumSet.of(DispatcherType.REQUEST, DispatcherType.ERROR, DispatcherType.ASYNC, DispatcherType.FORWARD, DispatcherType.INCLUDE), false, dispatcherServletReg.getName());

Spring Session不会设置粘性会话。相反，它允许任何JVM通过将会话对象放在中央数据存储区（即Redis）中来查找会话对象。
