springboot configuration redis serialization

Question

Why is the error "Could not autowire. No beans of 'RedisConnectionFactory' type found" reported here?

Serialization doesn't work

I used the new way to inject the object and it didn't solve the problem：

@Configuration
public class RedisConfig {
@Resource
private RedisConnectionFactory redisConnectionFactory;
@Bean
public RedisTemplate<Object,Object> redisTemplate(){
    RedisTemplate<Object,Object> redisTemplate=new RedisTemplate<>();
    Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
    redisTemplate.setConnectionFactory(redisConnectionFactory);

    redisTemplate.setKeySerializer(new StringRedisSerializer());
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);

    
    redisTemplate.setHashKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);

    
    redisTemplate.setStringSerializer(new StringRedisSerializer());
    return redisTemplate;
}

}
