Java代码实现清除Redis缓存

private static Jedis jedis = null;
    public static void del(String key){
        try {
            jedis = RedisPool.getRedis();
            //根据key清除缓存
            jedis.del(key);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
          jedis.close();
        }
    }
