当我从 Java8 迁移到 Java11 时，@Autowired 在测试类中失败获得不满意的依赖异常

问题描述

测试在 Java 8 上运行良好。但是一旦我将运行时更改为 JDK11，@Autowired 突然就不起作用了。当我这样做时，我收到以下异常。

这是示例测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:/spring/test-context.xml"})
public class SomeTest {

   @Autowired
   DummyRepositoryImpl dummyRepo;

   @Test
   public void letstest() {
       //Some code that uses dummyRepo
   }
}
