spring-boot - spring redis运行脚本: how to pass expiry time value

Question

我使用lua脚本:

local lock = redis.call('get', KEYS[1])
if not lock then    
    return redis.call('SETEX', KEYS[1], ARGV[1] ,ARGV[2] );
end
return false

我使用脚本从 spring boot 应用程序调用 redis

DefaultRedisScript<Boolean> redisScript = new
DefaultRedisScript<Boolean>();
redisScript.setScriptSource(new ResourceScriptSource(new ClassPathResource("checkandset2.lua")));
redisScript.setResultType(Boolean.class);
System.out.println(redisTemplate.execute(redisScript , Collections.singletonList("value123"),"10" ,"key123"));

我总是遇到异常:

当我使用

System.out.println(redisTemplate.execute(redisScript , Collections.singletonList("value123"),new Long(10) ,"key123"));

我得到异常

有什么建议可以将到期时间值传递给 lua 脚本吗？

我自己是新手，也遇到过类似的问题。尝试发送字符串 "10"，而不是 Long。为我工作。
