Error creating bean with name '...RedisHttpSessionConfiguration': Initialization of bean failed

I'm using Redis and created HttpSessionConfig file. Here is my code in

HttpSessionConfig.java:

@EnableRedisHttpSession
public class HttpSessionConfig {

    @Bean
    public LettuceConnectionFactory connectionFactory() {

        return new LettuceConnectionFactory();
    }

    @Bean
    public HttpSessionIdResolver httpSessionStrategy() {
        return HeaderHttpSessionIdResolver.authenticationInfo();
    }

}

And here is my pom.xml file:

    <!-- Redis -->
    <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>

But I got error: 

Error creating bean with name 'org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration':

Initialization of bean failed

More trace:

Anyone know how to fix it ???

In the stack trace the error tells that

java.lang.NoClassDefFoundError: io/lettuce/core/KeyValue

So add manually the dependency io.lettuce in your pom.xml

<dependency>
    <groupId>io.lettuce</groupId>
    <artifactId>lettuce-core</artifactId>
    <version>5.1.7.RELEASE</version>
</dependency>
