小贝子编程

升级Spring和Hibernate, HibernateTemplate等于null和classcastexcepti



我一直在尝试升级到最新版本的spring和hibernate。要让所有的东西正常工作，我遇到了很大的麻烦。

我使用Java Server Faces 2.0和Dynamic Web Library 3.0。

所以目前我在我的GenericDao课上得到了java.lang.ClassCastException: com.sun.proxy.$Proxy37 cannot be cast to org.hibernate.engine.spi.SessionImplementor在

return (getHibernateTemplate().execute(new HibernateCallback<T>()
    {
        @Override
        public T doInHibernate(Session session) throws HibernateException
        { // The Error  
            Criteria executableCriteria = criteria.getExecutableCriteria(session); 
            return (T) executableCriteria.uniqueResult();
        }
    }));

全音轨跟踪…

此外，我也一直在获取hibernate模板的NullPointerException s。

我刚刚将项目转换为maven项目，以便更好地了解库。我可以想象这个问题与我正在使用的库有关…

这是我的pom.xml

这是我的applicationContext.xml的一部分

    <bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="configLocation"
        value="classpath:com/xx/hibernate/mappings/hibernate.cfg.xml" />
</bean>
<bean id="abstractDaoTarget" class="com.xx.hibernate.daos.GenericDao"

        </bean>
    </property>
</bean>
作为解释，我稍后将把这些特定于类的dao注入到服务中。

和我的GenericDao类的一部分…

import org.springframework.orm.hibernate4.HibernateCallback;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
public class GenericDao<T> extends HibernateDaoSupport implements IGenericDao<T>, Serializable {

@Override
public void delete(T obj)
{
    getHibernateTemplate().delete(obj);
}
Hibernate配置

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property>
        <property name="hibernate.connection.password">pw</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost/xx</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
        <property name="hibernate.c3p0.min_size">5</property>

        <mapping resource="com/xx/hibernate/mappings/Battery.hbm.xml" />
        ...
    </session-factory>
</hibernate-configuration>

如果你们能帮我解决这个问题，那就帮了我一个大忙了。

如果您还需要看别的东西，请告诉我。

提前感谢!

正如M. Deinum指出的，我的资料完全过时了。

我重写了整个服务和dao…

     BaseDao<T> implements IBaseDao<T>
    {
        private Class<T> type;
        public BaseDao()
        {
        }
        public BaseDao(Class<T> type)
        {
            this.type = type;
        }
        private SessionFactory sessionFactory;
        @Override
        public void delete(T obj)
        {
            getSession().delete(obj);
        }
public Session getSession()
    {
        Session session = getSessionFactory().getCurrentSession();
        if (session == null)
        {
            session = getSessionFactory().openSession();
        }
        return session;
    }
    ...

我的applicationContext…

<bean id="userDao" class="com.xx.hibernate.daos.UserDao">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>    
<bean id="userService" class="com.xx.services.UserService">
    <property name="dao" ref="userDao" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

此外，我一直在我的服务中使用@Transactional注释。

我还更新了我的c3p0和eh-cache库到最新的hibernate版本。
