在spring boot项目中,尝试使用redisTemplate执行lua脚本。看来绝地武士不支持为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:

切换到要使用的莴苣驱动程序 EVALSHA 在集群环境中。

Spring Boot 1.5的配置。x可能看起来像:

@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);
}
