spring-boot redisTemplate execute script error: EvalSha is not supported in cluster environment

Question

Trying to execute lua script using redisTemplate, in a spring-boot project. Looks like jedis does not support executing lua script for redis cluster... Is there any other alternatives? Thanks!

redis config:

spring:
  redis:
    cluster:
      nodes:
        - 192.168.0.111:6390
        - 192.168.0.111:6391
        - 192.168.0.111:6392

code:

@Component
public class Example {

@Autowired
private RedisTemplate redisTemplate;

@Autowired
RedisScript<Boolean> script;

public boolean checkAndSet(String expectedValue, String newValue) {
    return (boolean) redisTemplate.execute(script, singletonList("key1"), asList(expectedValue, newValue));
}
}

error logs:

org.springframework.dao.InvalidDataAccessApiUsageException: EvalSha is not supported in cluster environment.

Switch to the Lettuce driver to use EVALSHA in a cluster environment.

A configuration for Spring Boot 1.5.x could look like:

@Bean
LettuceConnectionFactory redisConnectionFactory(RedisProperties redisProperties) {

    Cluster clusterProperties = redisProperties.getCluster();
    RedisClusterConfiguration config = new RedisClusterConfiguration(
            clusterProperties.getNodes());

    if (clusterProperties.getMaxRedirects() != null) {
        config.setMaxRedirects(clusterProperties.getMaxRedirects());
    }

    return new LettuceConnectionFactory(config);
}
