SpringBoot에서 Redis를 전역 잠금으로 사용하는 방법

public class CommonConsumerService {
    //库存个数
    static int goodsCount = 900;
    //卖出个数
    static int saleCount = 0;
    public static void main(String[] args) throws InterruptedException {
        for (int i = 0; i < 1000; i++) {
            new Thread(() -> {
                try {Thread.sleep(2);} catch (InterruptedException e) {}
                if (goodsCount > 0) {
                    goodsCount--;
                    System.out.println("剩余库存：" + goodsCount + " 卖出个数" + ++saleCount);
                }
            }).start();
        }
        Thread.sleep(3000);
    }
}
