用Spring测试JUnit时Hibernate 4的转换异常

Question

我用org.springframework.orm.Hibernate4.LocalSessionFactoryBean类创建了sessionFactory bean，用org.springframework.orm.Hibernate4.HibernateTransActionManager类创建了transactionManager bean。

请指教。

下面是JUnit测试的datasource.xml。测试在开发人员配置文件下运行。而确切的。xml代码在主应用程序的生产配置文件下平稳地运行。

Answer 1

您必须将引用传递给bean，而不是值。所以改变这个：

<property name="sessionFactory" value="sessionFactory"></property>

到

<property name="sessionFactory" ref="sessionFactory"></property>
