以下是一个基于Java的简单抢单功能实现示例，模拟多线程环境下的并发抢单场景，包含基本逻辑和线程安全处理：

订单类定义

定义一个订单类，包含订单ID和抢单状态：

public class Order {private final String orderId;private volatile boolean isTaken;public Order(String orderId) {this.orderId = orderId;this.isTaken = false;}public synchronized boolean takeOrder(String workerId) {if (!isTaken) {isTaken = true;System.out.println("Worker " + workerId + " took order: " + orderId);return true;}return false;}
}

抢单线程实现

模拟多个工作者线程同时抢单：

public class GrabOrderThread implements Runnable {private final Order order;private final String workerId;public GrabOrderThread(Order order, String workerId) {this.order = order;this.workerId = workerId;}@Overridepublic void run() {order.takeOrder(workerId);}
}

主程序测试

创建订单并启动多个线程模拟抢单：

public class Main {public static void main(String[] args) {Order order = new Order("ORDER_123");Thread worker1 = new Thread(new GrabOrderThread(order, "WORKER_001"));Thread worker2 = new Thread(new GrabOrderThread(order, "WORKER_002"));Thread worker3 = new Thread(new GrabOrderThread(order, "WORKER_003"));worker1.start();worker2.start();worker3.start();}
}
