notify-keyspace-events in Redis

Question

I'd like to work with Redis for manipulating sessions.But I get failure when running the spring boot app.So I guess that this error is coming from maven dependencies especially version conflicts.

Here is my maven dependencies:

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>

        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>io.lettuce</groupId>
            <artifactId>lettuce-core</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>biz.paluch.redis</groupId>
            <artifactId>lettuce</artifactId>
            <version>4.3.1.Final</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session</artifactId>
            <version>1.3.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>com.github.kstyrc</groupId>
            <artifactId>embedded-redis</artifactId>
            <version>0.6</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>


    </dependencies>

I tried to avoid notify-keyspace-events bug by integrating embedded-redis dependency in pom.xml but without success.

Notice that I added two dependencies in above pom.xml which there artifactId are spring-session-data-redis and lettuce-core.These dependencies are respectively responsible for Redis connection and ensuring thread safety for session connections.

Below the config class for redis http session:

@Configuration
@EnableRedisHttpSession
public class HttpSessionConfig {
    @Bean
    public LettuceConnectionFactory connectionFactory() {
        return new LettuceConnectionFactory(); 
    }

}

Also I configured http session management by using spring-session in below component:

import org.springframework.session.web.http.HeaderHttpSessionStrategy;
import org.springframework.session.web.http.HttpSessionStrategy;

    @Configuration
    @EnableWebSecurity
    public class SecurityConfig extends WebSecurityConfigurerAdapter {
        //some code here
        public HttpSessionStrategy httpSessionStrategy() {
                return new HeaderHttpSessionStrategy();
            }
    }

But when I run spring boot app, I get this following runtime error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in class path resource [org/springframework/session/data/redis/config/annotation/web/http/RedisHttpSessionConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.data.redis.RedisSystemException: Error in execution; nested exception is io.lettuce.core.RedisCommandExecutionException: ERR Unsupported CONFIG parameter: notify-keyspace-events

If you have this issue:

io.lettuce.core.RedisCommandExecutionException: ERR Unsupported CONFIG parameter: notify-keyspace-events

then add following configuration class in your application:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.ConfigureRedisAction;

@Configuration
public class RedisConfigureAction {
    @Bean
    public ConfigureRedisAction configureRedisAction() {
        return ConfigureRedisAction.NO_OP;
    }
}

I didn't need to configure a `ConfigureRedisAction` bean when the Redis cluster was not using encryption. Now that the Redis cluster IS using encryption, why is this bean suddenly necessary? What is it about adding encryption that causes this behavior? – Jack Straw Oct 24 '22 at 23:24

In my case - I had misconfigured lettuce client with client config for standalone server connecting to sentinel node. When I have changed client configuration of sentinel connecting to sentinel node exception went away.

FYI when using ConfigureRedisAction.NO_OP you have to have configure Redis redis.conf file with config set notify-keyspace-events Egx. See Redis documentation and default implementation of ConfigureRedisAction at Spring session source code.

Set these parameters in the property

spring:
  session:
    redis:
      configure-action: none
