集成Spring和Hibernate3。在創建bean時，應用程序引發異常

Question

下午好！ 我開始使用Spring和Hibernate框架進行依賴注入和具有數據持久性的控制反轉的研究。 我正在嘗試使用Spring集成兩者，以控制Spring監視的所有組件都可以作為依賴的SessionFactory來控制Hibernate SessionFactory，Spring控制一切。不幸的是我無法實現此目標，但收到以下異常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'produtosController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private br.com.caelum.estoque.dao.ProdutoDAO br.com.caelum.estoque.controller.ProdutosController.produtoDAO; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'produtoHibernateDAO' defined in file [C:\Program Files\eclipse\apache-tomcat-8.0.15\wtpwebapps\fj27-projeto-spring\WEB-INF\classes\br\com\caelum\estoque\dao\ProdutoHibernateDAO.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.hibernate.SessionFactory]: : Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/app-config.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/app-config.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]

從他所說的不能創建到“ SessionFactory”的bean，因此不能為持久化數據“ DAOS”創建bean。 我有一個問題的一周時間，我已經查看並查看了app-config.xml中的設置，嘗試了很多事情，嘗試了論壇，但是沒有任何嘗試，現在，我正在尋求您的幫助。

這是我的項目文件：

我試圖像這樣更改構造方法

@Autowired
public ProdutoHibernateDAO(SessionFactory factory) {
    session = factory.getCurrentSession();
}

和方法

public void salvar(Produto produto) {
    session.getSessionFactory().getCurrentSession().save(produto);
}

春季和冬眠的罐子都在版本4中。

Answer 1

我解決了問題。 我將兩個jars Spring都更改為Hibernate版本（Spring 4.1.4.RELEASE，Hibernate 4.3.8.Final）。 因此，我更改了app-config.xml文件，並讓他這樣做：

<!-- Configuração das propriedades do Hibernate -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.connection.url">jdbc:mysql://localhost/fj21</prop>
                <prop key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>
                <prop key="hibernate.connection.username">root</prop>
                <prop key="hibernate.connection.password">m19731973f</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.connection.autocommit">true</prop>
            </props>
        </property>
        <property name="annotatedClasses">
            <list>
                <value>br.com.caelum.estoque.model.Produto</value>
            </list>
        </property>
    </bean>

我認為應該存在jar版本沖突。 現在工作正常。 感謝大家的幫助。
