redis简单配置lua

redisSettring.getLUaPath是自己lua文件的路径

实现一个CAS 

文件内容：

local current = redis.call('GET', KEYS[1])
if current == ARGV[1]
  then redis.call('SET', KEYS[1], ARGV[2])
  return true
end
return false

JAVA中的实现

@Autowired
private RedisTemplate redisTemplate;

@Autowired
DefaultRedisScript redisScript;

/**
 * 测试redis  lua
 * @return
 */
@GetMapping("/lua")
public Object testredislua() {
    String key = "lua";
    redisTemplate.opsForValue().set(key, "source");
    String s = (String) redisTemplate.opsForValue().get(key);
    System.out.println(s);
    redisTemplate.execute(redisScript, Collections.singletonList(key), "source", "target");
    s = (String) redisTemplate.opsForValue().get(key);
    System.out.println(s);
    return null;
}
