在测试应用程序之前初始化Spring Boot测试bean

给定一个Spring Boot应用程序,它在启动时执行一些需要模拟服务器的操作:

@SpringBootApplication
public class Application implements ApplicationListener<ApplicationReadyEvent> {

  @Override
  public void onApplicationEvent(ApplicationReadyEvent event) {
    System.err.println("should be 2nd: application init (needs the mock server)");
  }

  public boolean doSomething() {
    System.err.println("should be 3rd: test execution");
    return true;
  }
}

因此,应提前初始化模拟服务器:

@SpringBootTest
@TestInstance(Lifecycle.PER_CLASS)
class ApplicationITest {

  @Autowired
  MockServer mockServer;

  @Autowired
  Application underTest;

  @BeforeAll
  void setUpInfrastructure() {
    mockServer.init();
  }

  @Test
  void doSomething() {
    assertTrue(underTest.doSomething());
  }
}

@Component
class MockServer {
  void init() {
    System.err.println("should be 1st: mock server init");
  }
}

但应用程序似乎总是先初始化:

should be 2nd: application init (needs the mock server)
should be 1st: mock server init
should be 3rd: test execution

我怎样才能按预定的顺序执行这些任务?

我试着用 Order(Ordered.HIGHEST_PRECEDENCE) 和 @AutoConfigureBefore 没有成功。
