Redisson是架設在Redis基礎上的一個Java駐記憶體資料網格（In-Memory Data Grid）。【Redis官方推薦】
適用場景
主要適用於以下幾種場景：
分散式應用，快取，分散式會話，分散式任務/服務/延遲執行服務，Redis客戶端

redisson初始化：

@Component
@Slf4j
public class RedissonManager {

    private Config config = new Config();

    private Redisson redisson = null;

    public Redisson getRedisson() {
        return redisson;
    }

    private static String redis1Ip = PropertiesUtil.getProperty("redis1.ip");
    private static Integer redis1Port = Integer.parseInt(PropertiesUtil.getProperty("redis1.port"));
    private static String redis2Ip = PropertiesUtil.getProperty("redis2.ip");
    private static Integer redis2Port = Integer.parseInt(PropertiesUtil.getProperty("redis2.port"));

    @PostConstruct
    private void init(){
        try {
            config.useSingleServer().setAddress(new StringBuilder().append(redis1Ip).append(":").append(redis1Port).toString());

            redisson = (Redisson) Redisson.create(config);

            log.info("初始化Redisson結束");
        } catch (Exception e) {
            log.error("redisson init error",e);
        }
    }
}
 

redisson分散式鎖實戰

    @Scheduled(cron="0 */1 * * * ?")
    public void closeOrderTaskV4(){
        RLock lock = redissonManager.getRedisson().getLock(Const.REDIS_LOCK.CLOSE_ORDER_TASK_LOCK);
        boolean getLock = false;
        try {
            if(getLock = lock.tryLock(0,50, TimeUnit.SECONDS)){
                log.info("Redisson獲取到分散式鎖:{},ThreadName:{}",Const.REDIS_LOCK.CLOSE_ORDER_TASK_LOCK,Thread.currentThread().getName());
                int hour = Integer.parseInt(PropertiesUtil.getProperty("close.order.task.time.hour","2"));
//                iOrderService.closeOrder(hour);
            }else{
                log.info("Redisson沒有獲取到分散式鎖:{},ThreadName:{}",Const.REDIS_LOCK.CLOSE_ORDER_TASK_LOCK,Thread.currentThread().getName());
            }
        } catch (InterruptedException e) {
            log.error("Redisson分散式鎖獲取異常",e);
        } finally {
            if(!getLock){
                return;
            }
            lock.unlock();
            log.info("Redisson分散式鎖釋放鎖");
        }
    }
