带有Karaf、Spring和JPA的LocalContainerEntityManagerFactoryBean

spring hibernate jpa

带有Karaf、Spring和JPA的LocalContainerEntityManagerFactoryBean,spring,hibernate,jpa,karaf,Spring,Hibernate,Jpa,Karaf,在许多情况下，在XML文件中声明数据源和持久性单元都不理想。为此，我尝试使用LocalContainerEntityManagerFactoryBean配置JPA。但首先，一些文献证明这种方法在非OSGI环境中有效： www.baeldung.com/2011/12/22/the-persistence-layer-with-spring-data-jpa/ docs.spring.io/spring/docs/current/spring-framework-reference/html/o

在许多情况下，在XML文件中声明数据源和持久性单元都不理想。为此，我尝试使用LocalContainerEntityManagerFactoryBean配置JPA。但首先，一些文献证明这种方法在非OSGI环境中有效：

  • www.baeldung.com/2011/12/22/the-persistence-layer-with-spring-data-jpa/
  • docs.spring.io/spring/docs/current/spring-framework-reference/html/orm.html
为此，我的Karaf OSGI包的源代码如下所示

    public class AbstractXyzTableServiceImpl
    {
        private static EntityManagerFactory _entityManagerFactory;

        MysqlDataSource mysqlDataSource = null;


        // private static final SessionFactory configurationSessionFactory = buildConfigurationSessionFactory();

        @Bean
        public DataSource dataSource()
        {
            final MysqlDataSource dataSource = new MysqlDataSource();

            dataSource.setServerName("localhost");
            dataSource.setDatabaseName("PSH");
            dataSource.setUser("root");
            dataSource.setPassword("password");

            return dataSource;
        }


        @Bean
        public Properties hibernateProperties()
        {
            final Properties properties = new Properties();

            properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
            properties.put("hibernate.connection.driver_class", "com.mysql.jdbc.Driver");
            // properties.put("hibernate.connection.driver_class", "mysql-pool-xa");
            // properties.put("hibernate.hbm2ddl.auto", "create-drop");

            return properties;
        }


        public EntityManagerFactory getEntityManagerFactory()
        {
            // _entityManagerFactory = Persistence.createEntityManagerFactory("Config");

            if (_entityManagerFactory == null)
                _entityManagerFactory = getEntityManagerFactory(dataSource(), hibernateProperties());
            return _entityManagerFactory;
        }


        @Bean
        public EntityManagerFactory getEntityManagerFactory(DataSource dataSource, Properties hibernateProperties)
        {
            final LocalContainerEntityManagerFactoryBean emfBean = new LocalContainerEntityManagerFactoryBean();
            //emfBean.setPersistenceUnitName("Config");
            emfBean.setDataSource(dataSource);
            emfBean.setPackagesToScan(new String[] { "info.test.configuration.data" });
            emfBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
            emfBean.setJpaProperties(hibernateProperties);
            emfBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
            //emfBean.setPersistenceXmlLocation("META-INF/persistence.xml");
            emfBean.afterPropertiesSet();

            return emfBean.getObject();
        }

    }
不幸的是，Spring/LocalContainerEntityManagerFactoryBean似乎坚持使用一个对应的persistence.xml文件，所有定义的属性都可能被覆盖。这很好，只是当部署在Karaf 4.0.0中时，我无法获得这段代码来查找persistence.xml文件。Karaf提供的堆栈跟踪如下：

这似乎是某种类型的类路径问题：

  • jira.spring.io/browse/SPR-8832
我的问题是：

  • 有没有其他人在Karaf/OSGI中采用了无XML的方法来初始化JPA，并可以分享他们的方法
  • 如果这是一个类路径问题，阻止LocalContainerEntityManagerFactoryBean在resources/META-INF目录中查找persistence.xml，那么有推荐的解决方案吗
提前感谢,，
Randy

对于初学者，我会尝试将您的配置更改为以下内容

public class AbstractConfigurationServiceImpl extends AbstractDao {

    @Bean
    public DataSource dataSource()
    {
        final MysqlDataSource dataSource = new MysqlDataSource();
        dataSource.setServerName("localhost");
        dataSource.setDatabaseName("PSH");
        dataSource.setUser("root");
        dataSource.setPassword("password");
        return dataSource;
    }


    @Bean
    public FactoryBean<EntityManagerFactory> entityManagerFactory()
    {
        final LocalContainerEntityManagerFactoryBean emfBean = new LocalContainerEntityManagerFactoryBean();
        emfBean.setDataSource(dataSource());
        emfBean.setPackagesToScan(new String[] { "info.test.configuration.data" });
        emfBean.setJpaVendorAdapter(hibernateJpaVendorAdapter());
        return emfBean;
    }

    @Bean
    public JpaVendorAdapter hibernateJpaVendorAdapter(){
        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        jpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect"
        return jpaVendorAdapter;
    }

}
}

首先，我会尝试更改您的配置
