Spring靴。类只在src/java/main中运行，在src/java/test中它有例外

Question

1. 我有一个Java/Spring-Boot类

@SpringBootApplication
@ComponentScan(value = "ignore")
@RunWith(SpringRunner.class)
public class MyApplication {
   @Bean
   YAMLConfig myeadFromYMLFile() {
      return new YAMLConfig();
   }
   public static void main(String[] args) throws InterruptedException {
      ConfigurableApplicationContext context = 
         SpringApplication.run(MyApplication.class, args);
      YAMLConfig myBean = context.getBean(YAMLConfig.class);
      myBean.doSomething();
      myBean.printApi();
   }
}

java prettyprint-override">@Configuration
@EnableConfigurationProperties
public class YAMLConfig {
   @Value("${refresh.rate}")
   private int refreshRate;
   @Value("${datasource.apiUrl}")
   private String apiUrl;
   public void doSomething() {
      System.out.printf("Refresh Rate : %s%n", refreshRate);
   }
   public void printApi() {
      System.out.printf("Refresh Rate : %s%n", apiUrl);
   }
   public String getApiUrl() {
      return apiUrl;
   }
}

问题：当我在src/java/main中运行类MyApplication时，一切都很酷。但是：当我在src/java/test中运行这个类时，它会失败

附注：我有spring-boot-starter-web依赖项。通过@springboottest，我得到了以下信息：
