2. Cause of error

Added a section to the Applicationcontext.xml:

<bean id= "Studentserviceimpl" class= "Com.you.user.service.impl.StudentServiceImpl" scope= "Singleton" lazy-init= "False" >
<property name= "Studentdao" ref= "Studentdaoimpl"/>
</bean>

3, the solution of the method

Remove this paragraph

Caused by:org.springframework.beans.factory.NoSuchBeanDefinitionException
