我已经为Web应用程序编写了集成测试，但是我不知道如何运行该测试。当我执行mvn test时，Maven构建失败并显示以下错误

[INFO] Compiling Kotlin sources from [src/main/kotlin]

package demo

@SpringBootApplication 
open class Application 
 
fun main(args: Array<String>) { 
    SpringApplication.run(Application::class.java, *args)

package demo

import demo.repository.CityRepository 
 
@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(classes = Application.class) 
@WebIntegrationTest({"server.port=8080"}) 
class CityControllerTest { 
    @Autowired 
    private var cityRepository: CityRepository? 
    private val restTemplate: RestTemplate = TestRestTemplate() 
    // ... 
} 

请您参考如下方法:
