Spring Boot ignores beans from Java config class using Spring Profile

Question

When I run my application on Eclipse with a classical context loading, no worries, the beans defines on the config class corresponding with the Spring Profile chosen are correctly instanciated.

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();
    }
}

But, when I run the application with Spring Boot, these beans are not instanciated.

@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);
    }
}

Here is the java configuration class for the "dev" Spring profile:

@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);
    }
}

Here the AbstractPersistenceConfig class containing the others beans not instanciated:

public abstract class AbstractPersistenceConfig {

    // Constants...

    // ************************** ABSTRACT METHODS **************************

    /**
    * Returns a property list containing the Hibernate properties.
    * 
    * @return the Hibernate properties.
    */
    public abstract Properties hibernateProperties();

    /**
    * Defines the application datasource bean corresponding with the current Spring Profile.
    * 
    * @return the application datasource bean corresponding with the current Spring Profile.
    */
    @Bean
    public abstract DataSource dataSource();

    /**
    * Defines the Hibernate session factory bean.
    * 
    * @return the {@code LocalSessionFactoryBean}.
    */
    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { HIBERNATE_PACKAGE_TO_SCAN });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
    }

    /**
    * Defines the bean allowing to Hibernate to support the transaction handling mechanism.
    * 
    * @return the {@code HibernateTransactionManager}.
    */
    @Bean
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory().getObject());
        return txManager;
    }

    // ************************** PROTECTED METHODS **************************

    // ...

    // ************************** PRIVATE METHODS **************************

    // ...
}

I tried to run the application with the following commands with the same result:

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

Concretely, the bean "sessionFactory" is not instanciated and cannot be injected into my GenericDaoImpl class...

I use the Spring Boot 1.0.2.RELEASE without the Spring Boot parent POM. I just defines this on the POM :

<dependencyManagement>
    <dependency>
        <!-- Import dependency management from Spring Boot -->
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-dependencies</artifactId>
        <version>${org.springframework.boot.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
</dependencyManagement>

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <mainClass>${start-class}</mainClass>
    </configuration>
</plugin>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-integration</artifactId>
    <version>${org.springframework.boot.version}</version>
</dependency>

Do you have some ideas?

Thanks a lot!!

Answer 1

I think you need to @Import your @Configuration class directly or use the @ComponentScan annotation. You initial example that uses ClassPathXmlApplicationContext will work because the XML processing happens early, and the <component-scan> will find your @Configuration classes before they are processed.

With the second example SpringApplication has already started processing your @Configuration classes and the XML is loaded via @ImportResource. By this time it is not possible for the XML <component-scan> to add more @Configuration.

Sort answer: Try @ComonentScan on your BasketHandlerLoader class.
