При попытке развернуть и запустить приложение загрузки spring в отдельном экземпляре tomcat (7), мы столкнулись с проблемой: autoconfigured spring datasource bean не найден и генерируется соответствующее исключение:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type [javax.sql.DataSource] found for dependency:
expected at least 1 bean which qualifies as autowire candidate for this dependency.

Простой jdbc spring.datasource правильно настроен в application.properties, и само приложение отлично работает со встроенным экземпляром tomcat в качестве автономного приложения загрузки spring.
Кажется, что файл application.properties не может быть прочитан и/или обработан надлежащим образом, или запуск какой-либо другой beans (например, службы в REST-контроллере) запускается до того, как была выполнена автоматическая настройка.
Требуется ли дополнительная настройка, если вы не используете встроенный tomcat? Или кто-нибудь сталкивается с подобными проблемами?
Простое приложение и конфигурация:
@EnableAutoConfiguration
@Configuration
@ComponentScan("com.foo")
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
application.properties:
spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driverClassName=com.mysql.jdbc.Driver
Пример использования источника данных:
@Repository
public class MyRepositoryImpl implements MyRepository {
@Autowired
private DataSource dataSource;
...
}
