Java优学网Spring事务管理讲解：掌握声明式事务配置与常见失效场景

@Service @Transactional public class OrderService {

@Transactional(readOnly = true)
public Order findOrderById(Long id) {
    // 查询操作
}

@Transactional(rollbackFor = Exception.class)
public void createOrder(Order order) {
    // 创建订单业务逻辑
}

}

@Service public class PaymentService {

public void processPayment(Payment payment) {
    // 这个方法内部调用不会触发事务
    updateOrderStatus(payment.getOrderId());
}

@Transactional
public void updateOrderStatus(Long orderId) {
    // 事务不会生效
}

}
