NoSuchBeanDefinitionException How to initialize a SessionFactory bean?

Question

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

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.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:967) at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:837) at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:749) 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 a SessionFacory bean:

 <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" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd"> <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" /> <mvc:annotation-driven /> <tx:annotation-driven /> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> <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="userService" class="com.example.service.impl.UserServiceImpl"> <property name="userDAO" ref="userDAO" /> </bean> <bean id="userDAO" class="com.example.dao.impl.hibernate.HibernateUserDAO" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="org.h2.Driver" /> <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> 

In addition, 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 class of service:

 @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 by clearing your configuration

it

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

Includes it all

 <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 you don’t need to explicitly identify all the beans (this would make scanning components quite useless if it were necessary).

Further these 2 beans

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

Already implies <mvc:annotation-driven />

You basically stay 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" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd"> <context:component-scan base-package="com.example" /> <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="driverClassName" value="org.h2.Driver" /> <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 this solves your problem, because the error is not related to the fact that the configuration is incomplete, but the configuration is in the wrong place. datasource , sessionFactory , transactionManager and <tx:annotation-driven .. /> need to be migrated to applicationContext.xml . Nex to the point that your applicationContext.xml should also include a scan component that scans everything but the controllers.

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

Change <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 will prevent duplicate instances of your @Service and @Repository beans. This is what is happening now (both your ContextLoaderListener and DispatcherServlet load and create the same beans, which will lead you to other nice exceptions and next to this duplication of memory, since you have 2 instances of each bean in memory).

Answer 2

If you use @Autowired, you do not need to declare as a property in context. But it should be in the context ---> NoSuchBeanDefinition -> not find it.

 <bean id="userService" class="com.example.service.impl.UserServiceImpl"> <property name="userDAO" ref="userDAO" /> </bean> 

try removing userDAO from the context of the property .-- if you auto-enlarge it, you don't need it in the context.

but the problem seems to be this bean:

 <bean id="userDAO" class="com.example.dao.impl.hibernate.HibernateUserDAO" /> 

can't introduce sessionFactory dependency, but everything seems to be correct :( why don't you try removing @autowired from the factory session, put get / set for the ref ref property in context in hibernateUserDao, just to check what happens?

Answer 3

Be that as it may, Spring is trying to say:

 There are multiple bean definitions... 

I had this problem:

 Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'metadataGeneratorFilter' is defined 

once when I had an xml file like this:

 <security:custom-filter ref="metadataGeneratorFilter" before="CHANNEL_FILTER"/> <beans:bean id="metadataGeneratorFilter" class="org.springframework.security.saml.metadata. MetadataGeneratorFilter"> <beans:constructor-arg ref="metadataGenerator"/> </beans:bean>
