従来のコンテキストをロードして Eclipse でアプリケーションを実行すると、選択した Spring プロファイルに対応する構成クラスで定義された Bean が正しくインスタンス化されます。

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();
    }
}

しかし、Spring Boot でアプリケーションを実行すると、これらの Bean はインスタンス化されません。

@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);
    }
}

「dev」Spring プロファイルの Java 構成クラスは次のとおりです。

@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);
    }
}

インスタンス化されていない他の Bean を含むAbstractPersistenceConfigクラスを次に示します。

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 **************************

    // ...
}

次のコマンドでアプリケーションを実行しようとしましたが、結果は同じでした:

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

具体的には、Bean「sessionFactory 」はインスタンス化されておらず、 GenericDaoImplクラスに注入できません...

Spring Boot 親 POM なしで Spring Boot 1.0.2.RELEASE を使用します。これを POM で定義するだけです:

<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>

何かアイデアはありますか？

どうもありがとう！！

クラスに直接、または注釈を使用@Importする必要があると思います。XML 処理が早期に行われるため、使用する最初の例が機能し、処理される前にクラスが検出されます。@Configuration@ComponentScanClassPathXmlApplicationContext<component-scan>@Configuration

2 番目の例でSpringApplicationは、すでに@Configurationクラスの処理が開始されており、XML は を介し​​てロードされてい@ImportResourceます。この時点で、XML<component-scan>にさらに を追加することはできません@Configuration。

並べ替えの答え:クラスで試してみ@ComonentScanてください。BasketHandlerLoader
