BeanCreationException во время работы сервера

Question

Я начинаю с небольшого приложения Spring MVC, и когда я запускаю сервер, у меня есть эта ошибка, я не знаю, что я делаю неправильно, и я пытаюсь понять почему @Autowiring не работает:

org.springframework.web.servlet.DispatcherServlet [main] Context initialization failed 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personDataAccesObject': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory org.munaycoop.taskmanager.daos.PersonDataAccesObject.session; nested exception is 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)}

Это мой дао:

@Repository 
@SuppressWarnings("rawtypes") 
public class PersonDataAccesObject implements IPersonDataAccesObject { 

    @Autowired 
    private SessionFactory session; 

, моя служба:

@Service 
@SuppressWarnings("unchecked") 
public class PersonService implements IPersonService { 

    @Autowired 
    private PersonDataAccesObject dao; 

и мой контроллер:}

@Controller 
public class PersonController { 

    @Autowired 
    private PersonService personService; 

это web.xml:

</beans:bean> 

Кажется, все правильно настроено, но что говорит мне Весна?

Если вам нужно что-то еще, сообщите мне.

Answer 1

Внутри вашего файла servlet-context.xml вы должны определить компонент sessionFactory и dataSource, как показано ниже.

<bean id="dataSource" 
    class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="org.hsqldb.jdbcDriver" /> 
    <property name="url" value="jdbc:hsqldb:mem://personDb" /> 
    <property name="username" value="sa" /> 
    <property name="password" value="" /> 
</bean> 


<bean id="sessionFactory" 
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="dataSource" /> 
    <property name="hibernateProperties"> 
    <props> 
     <prop key="hibernate.dialect">${hibernate.dialect}</prop> 
     <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop> 
    </props> 
    </property> 
</property> 

</bean>
