我的问题与其他问题一样，但我无法找到解决问题的方法。

的web.xml

异常日志：

1）

Error creating bean with name 'userDao' defined in ServletContext resource [/WEB-INF/spring-hibernate.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined

2）

No bean named 'sessionFactory' is defined

答案 0 :(得分：0)

请在spring-hibernate.xml中将sessionfactory id名称从sessionFactoryBean更改为sessionfactory以解决第二个错误（“没有定义名为'sessionFactory'的bean'）。
