会话工厂处于休眠状态

Question

会话工厂是休眠中的重量级对象，因此经常调用重量级对象是错误的，因此如果有人有实例，那么如何在整个项目中使用会话工厂的单个对象，请分享

Answer 1

In a Spring context, expose the sessionFactory as a bean.

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

    final LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource()).scanPackages("yourPackageNameHere");

    builder.addProperties(properties);

    return builder.buildSessionFactory();
}

The use the SessionFactory bean in another class

@Autowired private SessionFactory sessionFactory;
