您的错误堆栈跟踪包含

 nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.hibernate.LocalSessionFactoryBean]

因此无法找到类＆＃34; org.hibernate.LocalSessionFactoryBean＆＃34;。 类＆＃34; LocalSessionFactoryBean＆＃34;实际上存在于spring-orm jar中，并且完全限定名称取决于您使用的hibernate版本。

org.springframework.orm.hibernate3.LocalSessionFactoryBean
or
org.springframework.orm.hibernate4.LocalSessionFactoryBean
or
org.springframework.orm.hibernate5.LocalSessionFactoryBean

而不是

<bean id="mysessionFactory"  class="org.hibernate.LocalSessionFactoryBean">

你必须使用

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