Question

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
    at com.epam.hhhsystem.services.UtilMethods.createTestDb(UtilMethods.java:21)
    at com.epam.hhhsystem.services.UtilMethods.main(UtilMethods.java:31)

如何解决？

Answer 1

LocalSessionFactoryBean是FactoryBean基本上是创建另一种类型的对象。在这种情况下，SessionFactory。您无法按照自己的方式查找LocalSessionFactoryBean，因为这会导致SessionFactory。（这也可能是你想要的，而不是工厂）。

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

如果您真的希望FactoryBean本身的名称加上&，则会为您提供实际的FactoryBean，而不是FactoryBean的结果/创建。

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