我正在尝试创建一个简单的Spring-Hibernate集成的Maven项目，但遇到了
这样的异常"Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mysessionFactory' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError".
还有这个
"Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError".
。

在EmployeeDao类中放入@Autowired注释， 例如，
class EmployeeDao{
@Autowired
HibernateTemplate template;
}
