java - Jedis 中的响应对象 - 抛出 ClassCastException

Question

在 Jedis 中使用响应对象，抛出 ClassCastException 。当我使用管道时，我无法从 Redis 获得任何价值。请帮忙。我正在使用 Jedis 2.1.0

public class JedisPipeline {    
    public static void main(String args[]){
        final JedisPool pool = new JedisPool(new JedisPoolConfig(), "127.0.0.1", 6379);
        Jedis jedis = pool.getResource();
        Pipeline pipeline = jedis.pipelined();
        pipeline.multi();
        HashMap<String,String> map = new HashMap<String,String>();
        map.put("50", "50");
        pipeline.hmset("Id",map);
        Response <Long> incr = pipeline.hincrBy("Id", "100", 100);
        Response<Map<String,String>> map1 = pipeline.hgetAll("Id");
        pipeline.exec();
        List<Object> results = pipeline.syncAndReturnAll();
        System.out.println(results);
        System.out.println( incr.get());
        System.out.println( map1.get());
        pool.returnResource(jedis);
        pool.destroy();
    }
}

Exception in thread "main" java.lang.ClassCastException: [B cannot be cast to java.lang.Long

Answer 1

我使用的 jar 文件有冲突。我在构建路径中错误地保留了 jedis 2.1.0 和 jedis 2.0.0。
