Could not autowire. No beans of 'RedisConnectionFactory' type found.

This error occurs when Spring cannot find a bean of type 'RedisConnectionFactory' to autowire.

To resolve this issue, you should make sure that you have a Redis connection factory bean defined in your Spring configuration. Here's an example of how you can define a Redis connection factory bean in your configuration file:

@Configuration
public class RedisConfig {

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory();
    }

    // Other configuration beans and methods

}

In this example, we are using Lettuce as the Redis client library. You can replace it with any other Redis client library that you are using.

Make sure that you have the necessary dependencies for Redis and the chosen Redis client library in your project's build file (such as pom.xml for Maven or build.gradle for Gradle).

After defining the Redis connection factory bean, Spring should be able to autowire it correctly.
