java - 没有 Spring 的 Atomikos 事务管理器

Question

我尝试在不使用 spring 的情况下配置 Atomikos Transaction。首先，我尝试在不使用 spring 的情况下设置 EntityManagerFactory，以下是我尝试过的代码

private static AtomikosDataSourceBean prepareDataSource(){
        AtomikosDataSourceBean atomikosDataSourceBean = new AtomikosDataSourceBean();
        atomikosDataSourceBean.setUniqueResourceName("demo");
        atomikosDataSourceBean.setXaDataSourceClassName("oracle.jdbc.xa.client.OracleXADataSource");
        Properties properties = new Properties();
        properties.setProperty("user", "demo");
        properties.setProperty("password", "demo");
        properties.setProperty("URL", "dbc:oracle:thin:@localhost:1521/xe");
        atomikosDataSourceBean.setXaProperties(properties);
        return atomikosDataSourceBean;
    }


    public static EntityManagerFactory getEntityManagerFactory(){
        LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactory.setDataSource(prepareDataSource());
        entityManagerFactory.setPersistenceUnitName("demo");
        entityManagerFactory.setPersistenceXmlLocation("classpath*:META-INF/persistence.xml");
        Properties properties = new Properties();
        properties.setProperty("hibernate.transaction.jta.platform", "com.demo.AtomikosJtaPlatform");
        properties.setProperty("hibernate.show_sql", "true");
        return  (EntityManagerFactory) entityManagerFactory;

    }

上面的代码返回了一个classcastException。我怎样才能在不使用spring的情况下获得相同的entitymanagerfactory

我会引用 Atomikos 的官方文档，其中实际上为那些选择不使用 Spring 的人提供了一个示例:
