Question

在我搜索之前，我知道我的情况不单，但仍然认为我有个别问题。

所以，我的app-context.xml用于配置hibernate会话解析等。

<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>

我的属性文件是：

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.connectionValues=jdbc:mysql://localhost:3306/hibernateDB
jdbc.userName=root  
jdbc.password=25051988

我刚才提到这一行：访问被拒绝用户'root'@'localhost'（使用密码：YES）但我的所有connection.properties都是绝对正确的。

感谢您的帮助。

请注意，错误消息显示为Access denied for user 'root '@'localhost'。在属性文件中root之后有两个额外的空格。

无法打开Hibernate Session进行事务处理;嵌套异常是org.hibernate.exception.GenericJDBCException
