Redis实现过期监听,类似消息队列

使用Redis实现过期监听,类似消息队列,实现消息到期提醒,工单超时等功能
RedisTimeoutConfiguration配置类

@Configuration
public class RedisTimeoutConfiguration {
 
    @Autowired
    private RedisConnectionFactory redisConnectionFactory;
 
    @Bean
    public RedisMessageListenerContainer redisMessageListenerContainer() {
        RedisMessageListenerContainer redisMessageListenerContainer = new RedisMessageListenerContainer();
        redisMessageListenerContainer.setConnectionFactory(redisConnectionFactory);
        return redisMessageListenerContainer;
    }
 
    @Bean
    public KeyExpiredListener keyExpiredListener() {
        return new KeyExpiredListener(this.redisMessageListenerContainer());
    }
}

redisKey过期监听KeyExpiredListener类

@Slf4j
public class KeyExpiredListener extends KeyExpirationEventMessageListener {

  @Autowired private RedisCache redisCache;
  @Autowired private ISysMessageService sysMessageService;
  @Autowired private JdbcTemplate jdbcTemplate;

  private String sql = "update sys_message set status=? where id=?";

  public KeyExpiredListener(RedisMessageListenerContainer listenerContainer) {
    super(listenerContainer);
  }

  @Override
  public void onMessage(Message message, byte[] pattern) {
    String channel = new String(message.getChannel(), StandardCharsets.UTF_8);
    // 过期的key
    String key = new String(message.getBody(), StandardCharsets.UTF_8);
    System.out.println(message.toString());
    log.info("redis key 过期：pattern={},channel={},key={}", new String(pattern), channel, key);

    // 已过拜访时间
    if (key.contains(TransferConstant.VISIT_RECORD_READY)) {
      String[] split = key.split("-");
      updateMsgStatus(Long.parseLong(split[1]), 1);
      // 提前二十四小时提醒时间,
    } else if (key.contains(TransferConstant.VISIT_RECORD_WILL)) {
      String[] split = key.split("-");
      updateMsgStatus(Long.parseLong(split[1]), 0);
      // 获取当前消息记录
      SysMessage byId = sysMessageService.getById(Long.parseLong(split[1]));
      // 存入redis,准备24小时后过期
      redisCache.setCacheObject(
          TransferConstant.VISIT_RECORD_READY + "-" + byId.getId(),
          byId.getId(),
          Integer.parseInt(String.valueOf(byId.getVisitId() - System.currentTimeMillis())),
          TimeUnit.MILLISECONDS);
    }
  }
