notify-keyspace-events in Redis

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>

            <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

Please any help is very appreciated.Thanks in advance for your reply.

Solution

  • 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;
    }
}
