我可以使用以下Spring Session配置连接到Redis的Azure缓存:
<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:

该应用程序然后挂了一段时间，最终我得到了这个错误

当我使用在
localhost上运行的redis时，这些相同的bean可以正常工作。我在这里做错了什么？
最佳答案
首先，RedisHttpSessionConfiguration试试(默认情况下)enable键空间通知。但这仅适用于不安全的实例。
Docs表单类ConfigureNotifyKeyspaceEventsAction
解释为什么它只能在本地主机上工作:
并说明如何配置它以与安全的Redis实例一起使用。
简单使用方法:RedisHttpSessionConfiguration#setConfigureRedisAction设置ConfigureRedisAction#NO_OP，然后在您的redis实例调用中设置:config set notify-keyspace-events Egx
关于redis - 创建名称为 'enableRedisKeyspaceNotificationsInitializer'的bean时出错，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/60306331/
