@JFinal 你好，想跟你请教个问题：就是final整合redisa插件的时候，出现了JedisConnectionException: Could not get a resource from the pool出错。流程是这样子的，我在Linux服务器上安装了redis,修改密码，启动服务，然后jfinal 连接

public static void main(String[] args) {
        RedisPlugin rp = new RedisPlugin("userCache", "主机host", 6379, "redis");
        rp.start();

        Cache userCache = Redis.use("userCache");
        userCache.setex("phone", 20, "123455");
        System.out.println(userCache);
    }

Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
