我知道我的情況不單一，在我搜索之前，但仍然認爲我有個人問題。無法打開Hibernate Session進行事務處理;嵌套的異常是org.hibernate.exception.GenericJDBCException

所以，我的應用程序，其中的context.xml我做的配置Hibernate的Session anatation等
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName"><value>${jdbc.driverClassName}</value></property>
<property name="url"><value>${jdbc.connectionValues}</value></property>
<property name="username"><value>${jdbc.userName}</value></property>
<property name="password"><value>${jdbc.password}</value></property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref ="sessionFactory"/>
</bean>
<context:property-placeholder location="connection.properties"/>
<tx:annotation-driven transaction-manager="transactionManager"/>
<context:component-scan base-package="rus.spring.hibernate" />
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref ="dataSource"/>
<property name="packagesToScan" value="rus.spring.hibernate"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.max_fetch_depth">3</prop>
<prop key="hibernate.jdbc.fetch_size">50</prop>
<prop key="hibernate.jdbc.batch_size">10</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
</beans>
我的屬性文件是：
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.connectionValues=jdbc:mysql://localhost:3306/hibernateDB
jdbc.userName=root
jdbc.password=25051988
我剛剛提到這條線： 訪問拒絕用戶'root'@'localhost'（使用密碼：YES），但是我的所有connection.properties都是絕對正確的。
謝謝你的幫助。
