java - 嵌入式redis无法启动 - ERR Unsupported CONFIG parameter : notify-keyspace-events

Question

我使用的是 embedded-redis 0.6 版本和 spring-session-data-redis 1.0.1.RELEASE。在使用 mvn spring-boot:run 命令执行 spring boot 后，tomcat 服务器启动但嵌入式 redis 立即抛出以下异常(参见下面的完整堆栈跟踪):

redis.clients.jedis.exceptions.JedisDataException: ERR Unsupported CONFIG parameter: notify-keyspace-events

我该如何解决这个问题？

我的 pom.xml:

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
    <version>1.0.1.RELEASE</version> 
</dependency>
<dependency>
    <groupId>com.github.kstyrc</groupId>
    <artifactId>embedded-redis</artifactId>
    <version>0.6</version>
</dependency>

错误通常发生在以下两种情况之一:

Redis版本太旧

这似乎是最有可能的答案。来自 the documentation :

For the sample to work, you must install Redis 2.8+ on localhost and run it with the default port (6379). Alternatively, you can update the JedisConnectionFactory to point to a Redis server.

如果您不关心接收事件，您可以通过creating a ConfigureRedisAction Bean 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配置命令

嵌入式实例不太可能出现这种情况，因为默认情况下会进行配置。来自文档:

If you are using @EnableRedisHttpSession the SessionMessageListener and enabling the necessary Redis Keyspace events is done automatically. However, in a secured Redis enviornment the config command is disabled. This means that Spring Session cannot configure Redis Keyspace events for you. To disable the automatic configuration add ConfigureRedisAction.NO_OP as a bean.

For example, Java Configuration can use the following:

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

或XML

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