org.springframework.context.ApplicationContextException: пул подключений к базе данных настроен неправильно

Question

У меня есть приложение Spring Boot, которое я создал с помощью jHipster, я пытаюсь запустить некоторые тестовые примеры интеграции, и я настроил класс тестового примера, используя следующие аннотации:

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(classes = Application.class) 
@WebAppConfiguration 
@IntegrationTest 
@Transactional 
public class ScheduleRepositoryTests {.... 

Но все же я получаю вышеупомянутое исключение. Трассировка стека выглядит следующим образом:

Answer 1

Как уже упоминалось здесь: https://github.com/jhipster/generator-jhipster/issues/596

это ошибка. И обходной путь, чтобы сделать его работать, чтобы добавить «@ActiveProfiles („Dev“)» в качестве аннотации уровня класса на классе тестового примера:

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(classes = Application.class) 
@WebAppConfiguration 
@IntegrationTest 
@ActiveProfiles("dev") 
@Transactional 
public class ScheduleRepositoryTests {... 

Здесь «Dev» параметров сигналов в сторону «APPLICATION- dev.yml ', который используется для конфигурации тестов, в зависимости от типа среды, которую вы настроили.
