我写了这样的代码:

import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
...
ApplicationContext context = new ClassPathXmlApplicationContext(
"test/BeanConfig.xml");
LocalSessionFactoryBean localSessionFactoryBean;
localSessionFactoryBean = (LocalSessionFactoryBean) context.getBean("sessionFactory");

我看到了:

Exception in thread "main" java.lang.ClassCastException: org.hibernate.internal.SessionFactoryImpl cannot be cast to org.springframework.orm.hibernate4.LocalSessionFactoryBean

如何解决?

最佳答案

LocalSessionFactoryBean 是一个FactoryBean,基本上是创建另一种类型的对象。在本例中是一个 SessionFactory。您不能按照您正在执行的方式查找 LocalSessionFactoryBean,因为这将导致生成 SessionFactory。 (这也可能是您想要的,而不是工厂)。

ApplicationContext context = new ClassPathXmlApplicationContext("test/BeanConfig.xml");
SessionFactory localSessionFactoryBean context.getBean("sessionFactory", SessionFactory.class);

如果您真的想要 FactoryBean 本身在名称前加上 & ,这将为您提供实际的 FactoryBean 而不是结果/创建FactoryBean

ApplicationContext context = new ClassPathXmlApplicationContext("test/BeanConfig.xml");
LocalSessionFactoryBean localSessionFactoryBean context.getBean("&sessionFactory", LocalSessionFactoryBean .class);
