Spring Boot игнорирует бобы из класса java config, используя профиль Spring
когда я запускаю свое приложение на Eclipse с классической загрузкой контекста, не беспокойтесь, бобы определяют класс config, соответствующий выбранному профилю Spring, правильно инстанцированы.
public class BasketHandlerLoader {
public static void main(String[] args) throws Exception {
@SuppressWarnings("resource")
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:config/spring/spring-archibald-basket-handler-context.xml");
context.registerShutdownHook();
}
}
но, когда я запускаю приложение с Spring Boot, эти бобы не создаются.
@Configuration
@ImportResource("classpath:config/spring/spring-archibald-basket-handler-context.xml")
public class BasketHandlerLoader {
public static void main(String[] args) throws Exception {
SpringApplication.run(BasketHandlerLoader.class, args);
}
}
вот класс конфигурации java для весеннего профиля" dev":
@Configuration
@Profile("dev")
@EnableTransactionManagement
@PropertySources(value = { @PropertySource("classpath:filters/dev.properties") })
public class DevPersistenceConfig extends AbstractPersistenceConfig {
@Inject
private Environment env;
@Override
@Bean
public DataSource dataSource() {
return super.createDataSource(env);
}
@Override
public Properties hibernateProperties() {
return super.createHibernateProperties(env);
}
}
public abstract class AbstractPersistenceConfig {
// Constants...
// ************************** ABSTRACT METHODS **************************
/**

public abstract Properties hibernateProperties();
/**

@Bean
public abstract DataSource dataSource();
/**

@Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(new String[] { HIBERNATE_PACKAGE_TO_SCAN });
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
/**

@Bean
public HibernateTransactionManager transactionManager() {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(sessionFactory().getObject());
return txManager;
}

Я попытался запустить приложение со следующими командами с тем же результатом:
java -jar archibald-basket-handler-1.0-SNAPSHOT.jar --spring.profiles.active=dev
java -jar -Dspring.profiles.active=dev archibald-basket-handler-1.0-SNAPSHOT.jar
конкретно, драже "sessionFactory" не instanciated и не может быть впрыснут в мое GenericDaoImpl класса...

Я использую Spring Boot 1.0.2.Отпустите без родительского POM Spring Boot. Я просто определяю это на POM :

у вас есть какие-то идеи?
Спасибо большое!!

Я думаю, вам нужно @Import код @Configuration класс напрямую или используйте @ComponentScan Примечание. Вы первоначальный пример, который использует ClassPathXmlApplicationContext будет работать, потому что обработка XML происходит рано, и <component-scan> найдете свой @Configuration классы перед их обработкой.
со вторым примером SpringApplication уже начал обработку вашего @Configuration классы и XML загружается через @ImportResource. К этому времени это невозможно для XML <component-scan> добавить больше @Configuration.
сортировка ответ: попробуйте @ComonentScan на BasketHandlerLoader класса.
большой!!! Работает! Большое большое спасибо, Фил (за решение и объяснения!): -)
@Configuration
@ImportResource("classpath:config/spring/spring-archibald-basket-handler-context.xml")
@ComponentScan(basePackages = { "fr.ina.archibald.dao.config.persistence" }, includeFilters = @ComponentScan.Filter(value = Component.class, type = FilterType.ANNOTATION))
public class BasketHandlerLoader {
public static void main(String[] args) throws Exception {
SpringApplication.run(BasketHandlerLoader.class, args);
}
}
