服务无法在springboot中启动

Question

我正在使用rest-assured和Spring Boot编写测试。不幸的是，服务没有在测试中开始。这是我的代码：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = ServiceApplication.class)
@WebAppConfiguration
@IntegrationTest("server.port:8083")
@Slf4j
public class ServicePingIT {

    @Value("${local.server.port}")
    int port;
    private String Uri = "/service/ping";
    private String validation = "Service is up and running...";

    @Before
    public void setup() {
        RestAssured.port = port;
        RestAssured.baseURI="http://localhost";
    }

    @Test
    public void validatePingBody() {
        log.info("");
        validateREsponse(Uri, validation);
    }

我的测试设置有什么问题，服务没有启动？在日志中我确实看到Tomcat在端口启动但是失败并出现此错误：

ERROR 7432 --- [cat-startStop-1] org.apache.catalina.core.ContainerBase   : A child container failed during start

java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].StandardContext[/service]]
