NoSuchBeanDefinitionException How to initialise SessionFactory bean?

Question

I have a question. I tried to run my web application using Spring and Hibernate/ I have a strange error. NoSuchBeanDefinitionException. Stacktrace is:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:486)

I do not know why, because in my servlet-context.xml I declared SessionFacory bean:

Also, I annotated all DAO implementations and service implementations. Any ideas?

Added

This is part of my code:

@Repository
public class HibernateUserDAO implements UserDAO {
   @Autowired
   private SessionFactory sessionFactory;
   ...
}

And Service class:

@Service
public class UserServiceImpl implements UserService, UserDetailsService {
@Autowired
private UserDAO userDAO;

@Override
@Transactional
public void create(User user) throws SQLException {
    userDAO.create(user);
}

Answer 1

I would start with cleaning your configuration

This

<context:component-scan base-package="com.example" />

Includes all this

<context:component-scan base-package="com.example" />
<context:component-scan base-package="com.example.service" />
<context:component-scan base-package="com.example.service.impl" />
<context:component-scan base-package="com.example.dao" />
<context:component-scan base-package="com.example.dao.impl.hibernate" />
<context:component-scan base-package="com.example.web.controller" />
<context:component-scan base-package="com.example.entity" />

You are using component scanning so no need to explicitly define all the beans (it would make component scanning pretty useless if that was still needed).

Next these 2 beans

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

Are already implied by <mvc:annotation-driven />

Basically leaves you with this

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<mvc:annotation-driven />
<tx:annotation-driven />

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/pages/" />
    <property name="suffix" value=".jsp" />
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">

    <property name="url" value="jdbc:h2:~/userdb" />
    <property name="username" value="user" />
    <property name="password" value="pswd" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.example.entity.User</value>
            <value>com.example.entity.Role</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <value>
            hibernate.dialect=org.hibernate.dialect.H2Dialect
            hibernate.show_sql=true
        </value>
  </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

Not that it will solve your problem because the error is not due to the fact that the configuration is incomplete, but the configuration is in the wrong place. The datasource, sessionFactory, transactionManager and <tx:annotation-driven .. /> must be moved to the applicationContext.xml. Nex to that your applicationContext.xml should also include a component-scan which scans for everything but controllers.

    <context:component-scan base-package="com.example">
    <context:exclude-filter type="annotation" value="org.springframework.stereotype.Controller" />
</context:component-scan">

Change the <component-scan .. /> in your servlet-context.xml to

<context:component-scan base-package="com.example" use-default-filters="false">
    <context:include-filter type="annotation" value="org.springframework.stereotype.Controller" />
</context:component-scan">

This to prevent duplicate instantiation of your @Service and @Repository beans. Which is what is happening now (both your ContextLoaderListener and DispatcherServlet are loading and creating the same beans, which would lead you to other nice exceptions and next to that duplication of memory as you have 2 instances of each bean in memory).
