嵌入式redis无法启动

Question

我正在使用embedded-redis 0.6版本和spring-session-data-redis 1.0.1.RELEASE我仍然得到以下例外:
我使用spring引导与mvn spring-boot:运行命令tomcat服务器启动但嵌入式redis给出运行时的异常.

错误通常发生在以下两种情况之一:

Redis版本太旧了

这似乎是最可能的答案.从文档:

要使示例正常工作,必须在localhost上安装Redis 2.8+并使用默认端口(6379)运行它.或者,您可以更新JedisConnectionFactory以指向Redis服务器.

如果您不关心接收事件,可以通过创建ConfigureRedisAction Bean来禁用键空间通知设置:

@Bean
public static ConfigureRedisAction configureRedisAction() {
    return ConfigureRedisAction.NO_OP;
}

或XML

<util:constant
    static-field="org.springframework.session.data.redis.config.ConfigureRedisAction.NO_OP"/>

或者,确保您运行的是Redis 2.8+.

您的Redis实例已禁用或重命名了config命令

嵌入式实例的情况不太可能,因为默认配置也是如此.从文档:

如果您正在使用@EnableRedisHttpSession,则会自动完成SessionMessageListener并启用必要的Redis Keyspace事件.但是,在安全的Redis环境中,config命令被禁用.这意味着Spring Session无法为您配置Redis Keyspace事件.要禁用自动配置,请将ConfigureRedisAction.NO_OP添加为bean.

例如,Java Configuration可以使用以下内容:

@Bean
public static ConfigureRedisAction configureRedisAction() {
    return ConfigureRedisAction.NO_OP;
}

或XML

<util:constant
    static-field="org.springframework.session.data.redis.config.ConfigureRedisAction.NO_OP"/>
