Java jUnit测试中自动连线依赖项的注入失败，在控制器中工作

我被这个错误缠住了，希望有人能给我指出正确的方向。我有一个多模块maven项目。我想对我创建的一些服务进行单元测试。有趣的是，我正在为web服务的控制器中自动连接相同的服务。这是可行的，我没有自动布线的例外。所以我编写了下面的测试来检查它是否有效

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:*applicationContext.xml"})
public class ProductControllerTest {

    @Autowired
    TicketService ticketSvc;

    @Test
    public void equals() {
        // random test just to check if autowiring works
        List<Ticket> tickets = ticketSvc.getAll();
        assertEquals(tickets.size(), 2);
    }

}

以下是我在applicationContext.xml中扫描包的方式：

<context:component-scan base-package="nl.chess.mticketing.*"/>
<mvc:annotation-driven />

已解决：

如以下评论所示：

@ContextConfiguration(locations = {"classpath*:*applicationContext.xml"})

此表示法不提供有关applicationContext的反馈（如果实际找到该文件）。它直接进入“无法自动连线异常”。实际问题是找不到applicationContext。我将符号更改为：

@ContextConfiguration("classpath:/META-INF/applicationContext.xml")

---

在我更改了表示法之后，我又遇到了一些ApplicationContext错误，但是能够调试这些错误

注意，当您将

类路径*

与

*

一起使用时，如果找不到文件，Spring不会提供错误。我建议您删除

*

，查看是否找到了文件。我相信不是。我将要发表相同的评论，请将此评论视为对建议的支持谢谢各位，我已经尝试了许多不同的注释来查找应用程序上下文，所有这些都导致了此错误。我将尝试不带*的方法，并返回结果！谢谢约翰B和奴隶主人，你们是对的。我把问题标记为已解决！你能补充你的答案吗？
