redis zset 延迟合并任务处理

redis zset 延迟合并任务处理

@Autowired
    public RedisTemplate redisTemplate;

##1.发送端：在接口中收集任务ID,累计时间段之后，合并处理。
##redis zset 主键，任务ID(不重复)，时间戳
String key = "任务分组名称";
//延时
redisTemplate.opsForZSet().add(key,taskId,System.currentTimeMillis());
System.out.println("加入任务， taskId: " + taskId + ", exeTime: " + System.currentTimeMillis() + ", 当前时间：" + LocalDateTime.now() +",key = " + key);

##2.接收端
