我可以通过以下spring会话配置连接到azure cache for redis：

<bean id="redisPassword" class="org.springframework.data.redis.connection.RedisPassword">
    <constructor-arg index="0" value="xxxxxxxxxxxxxxxx"/>
</bean>

<bean id="redisStandaloneConfiguration" class="org.springframework.data.redis.connection.RedisStandaloneConfiguration">
    <property name="hostName" value="acmedev.redis.cache.windows.net"/>
    <property name="port" value="6380"/>
    <property name="password" ref="redisPassword"/>
</bean>

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

<bean class="org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory">
    <constructor-arg index="0" ref="redisStandaloneConfiguration"/>
</bean>

我的应用成功连接：

[lettuce-nioEventLoop-4-1] DEBUG io.lettuce.core.RedisClient - Connecting to Redis at acmedev.redis.cache.windows.net:6380: Success

然后应用程序挂起了一段时间，我最终得到了这个错误

当我在上运行redis时，同样的bean工作得很好 localhost .
我做错什么了？

首先 RedisHttpSessionConfiguration 尝试（默认情况下）启用键空间通知。但这只适用于不安全的示例。
文档窗体类configurenotifykeyspaceeventsaction解释为什么它只能在本地主机上工作：
如果redis示例得到了适当的保护，那么这个策略将不起作用。相反，应该在外部配置redis示例，并且应该公开configureredisaction#no#op类型的bean。
并解释如何配置它以使用安全的redis示例。
简单使用方法： RedisHttpSessionConfiguration#setConfigureRedisAction 设置 ConfigureRedisAction#NO_OP 例如，在redis示例调用中： config set notify-keyspace-events Egx

创建名为“enablerediskeyspacenotificationsinitializer”的bean时出错
