Comment configurer les paramètres de connexion Hibernate Db dans JAVA based spring config

Actuellement, je déplace mes paramètres de création et de configuration de beans de XML à spring config basé sur JAVA. Je suis coincé avec le déplacement des paramètres de base de données? Comment puis-je écrire ces paramètres de base de données hibernate dans un fichier de configuration basé sur JAVA?

<bean
    class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="hibernateProperties">
        <value>
            hibernate.connection.driver_class=com.mysql.jdbc.Driver
            hibernate.connection.url=jdbc:mysql://url
            hibernate.connection.username=username
            hibernate.connection.password=password
            hibernate.dialect=org.hibernate.dialect.HSQLDialect
            hibernate.show_sql=false
            </value>

    </property>
    <property name="packagesToScan" value="com.test" />

</bean>


<tx:annotation-driven />

<bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven proxy-target-class="true" />

J'ai ajouté les détails de la transaction. Je reçois cette exception:

Causé par: java.lang.ClassNotFoundException: org.hiberner.cadre.le spi.CurrentSessionContext

Voici la configuration. J'ai également ajouté des fonctionnalités de gestion des transactions dont vous aurez certainement besoin dans la solution finale.

import java.util.Properties;
import javax.sql.DataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource
import org.springframework.orm.hibernate3.HibernateTransactionManager;
import org.springframework.orm.hibernate3.LocalSessionFactoryBean
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
public class DbConfig{

@Bean
public DataSource getDatasource() {

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://url");
        dataSource.setUsername("username");
        dataSource.setPassword("password");

        return dataSource;
    }

@Bean
public SessionFactory getSessionFactory() throws IOException{

LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
 sessionFactoryBean.setPackagesToScan("com.test");

//getHibernateProperties method is a private method 

  sessionFactoryBean.setHibernateProperties(getHibernateProperties());
    sessionFactoryBean.setDataSource(getDatasource());
    sessionFactoryBean.afterPropertiesSet();

    return sessionFactoryBean.getObject();
}

@Bean
    public HibernateTransactionManager getTransactionManager() throws IOException{
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(getSessionFactory());

        return transactionManager;
   }


private static Properties getHibernateProperties() {

        Properties hibernateProperties = new Properties();
        hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
        hibernateProperties.put("hibernate.show_sql", false);
        // other properties

        return hibernateProperties;
    }

La réponse acceptée n'est pas complète. Ce code m'a aidé:


@Configuration
@ComponentScan(basePackageClasses = {массив пакетов с классами @Component, @Service, @Repository, @Controller})
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.jdev.blog.admin.crud.repositories", entityManagerFactoryRef = "entityManagerFactory")
public class ApplicationConfiguration { 
   @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
        dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
        dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
        dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));

        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);

        entityManagerFactoryBean.setJpaProperties(hibProperties());

        return entityManagerFactoryBean;
    }

    private Properties hibProperties() {
        Properties properties = new Properties();
        properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
        properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
        return properties;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
        return transactionManager;
    }
}
