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

Question

尝试在 spring-boot 项目中使用 redisTemplate 执行 lua 脚本。看起来 jedis 不支持为 redis 集群执行 lua 脚本...还有其他选择吗？谢谢！

redis 配置：

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

代码：

@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));
}
}

错误日志：

切换到 Lettuce 驱动程序以在集群环境中使用 EVALSHA。

Spring 引导 1.5.x 的配置可能如下所示：

@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);
}
