@RunWith(SpringRunner.class)
@SpringBootTest(classes = {EventApplication.class})
public class OrderServiceImplTest extends TestCase {

    @Autowired
    private ApplicationContext applicationContext;
    @Test
    public void testCreateOrder() {
        System.out.println("下单成功");
        //事件需要的信息封装
        ArrayList<String> arrayList = new ArrayList<>();
        arrayList.add("订单序号");
        arrayList.add("订单商品名");
        arrayList.add("订单商金额");
        //封装事件对象
        OrderCreateEvent orderCreateEvent = new OrderCreateEvent(this, "油卡充值订单", arrayList);
        //发布事件
        applicationContext.publishEvent(orderCreateEvent);
