java - 通过@Resource创建bean时出错

Question

我厌倦了使用 spring+hibernate+maven+postgreSQL 构建一个小型应用程序，但是当我厌倦在我的 Controller 和服务类中注入(inject)依赖项时，它会产生注入(inject)依赖项的问题，这里是代码和日志，请提供您的有建议解决这个接线问题吗？

Answer 1

您可能没有使用正确的sessionFactory类。如果您使用的是 Hibernate 4，请使用 LocalSessionFactoryBean 而不是 AnnotationSessionFactoryBean。

替换

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

由

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
