当我尝试运行此代码时，我发现了我发布的异常。自动注射没有发生。有什么问题？
答案 0 :(得分：0)
仔细看看例外，它说
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
看起来你没有创建sessionFactory bean。确保在弹簧配置中添加了sessionFactory
例如：
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:configLocation="${hibernate.config}"
/>
