[Java] 解决redisTemplate中leftPushAll隐性bug的问题

String key = String.format("test_key:%s", System.currentTimeMillis()/1000);
  String key2=key+"_2";
  String key3=key+"_3";
  List<String> t1=new ArrayList<>();
  t1.add("2");
  t1.add("3");
  t1.add("4");
  t1.add("5");
  t1.add("1");
  redisTemplate.opsForList().leftPushAll(key, t1);
  redisTemplate.opsForList().leftPushAll(key3, t1.toArray());
  redisTemplate.opsForList().leftPushAll(key2,new String[]{"dfdg","dgdaasdf","gdadfdf"});
