Question

我有多个数据源，动态会话映射在我使用“org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean”时工作正常现在我已经将我的应用程序升级到hibernate 4并开始使用“org.springframework”。 orm.hibernate4.LocalSessionFactoryBean”。出于某种原因，hibernate无法映射我的第二个数据源中的表。

这是我的配置。

<bean id="DataSource1" class="org.apache.commons.dbcp.BasicDataSource"
    autowire="byName" destroy-method="close">
    <property name="driverClassName" value="$api{d1.jdbc.driver}" />
    <property name="url" value="$api{d1.jdbc.url}" />
    <property name="username" value="$api{d1.jdbc.username}" />
    <property name="password" value="$api{d1.jdbc.password}" />
    <property name="maxActive" value="$api{dbcp.maxActive}" />
    <property name="maxWait" value="$api{dbcp.maxWait}" />
    <property name="minIdle" value="$api{dbcp.minIdle}" />
    <property name="maxIdle" value="$api{dbcp.maxIdle}" />
    <property name="validationQuery" value="$api{dbcp.validationQuery}" />
    <property name="testOnBorrow" value="true" />
</bean>
<bean id="d1SessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
    autowire="byName">
    <property name="dataSource" ref="DataSource1" />
    <property name="annotatedClasses">
        <list>
            <value>com.class1</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.hbm2ddl.auto">validate</prop>
            <prop key="hibernate.current_session_context_class">thread</prop>
            <prop key="hibernate.transaction.flush_before_completion">true</prop>
            <prop key="hibernate.transaction.auto_close_session">true</prop>

        </props>
    </property>
</bean>
<bean id="d1Dao" class="com.DaoImpl"
    autowire="byName">
    <property name="sessionFactory" ref="d1SessionFactory"></property>
</bean>

第二个会话定义是

<bean id="DataSource2" class="org.apache.commons.dbcp.BasicDataSource"
    autowire="byName" destroy-method="close">
    <property name="driverClassName" value="$api{d1.jdbc.driver}" />
    <property name="url" value="$api{d1.jdbc.url}" />
    <property name="username" value="$api{d2.jdbc.username}" />
    <property name="password" value="$api{d2.jdbc.password}" />
    <property name="maxActive" value="$api{dbcp.maxActive}" />
    <property name="maxWait" value="$api{dbcp.maxWait}" />
    <property name="minIdle" value="$api{dbcp.minIdle}" />
    <property name="maxIdle" value="$api{dbcp.maxIdle}" />
    <property name="validationQuery" value="$api{dbcp.validationQuery}" />
    <property name="testOnBorrow" value="true" />
</bean>
<bean id="d2SessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
    autowire="byName">
    <property name="dataSource" ref="DataSource2" />
    <property name="annotatedClasses">
        <list>
            <value>com.class2</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.hbm2ddl.auto">validate</prop>
            <prop key="hibernate.current_session_context_class">thread</prop>
            <prop key="hibernate.transaction.flush_before_completion">true</prop>
            <prop key="hibernate.transaction.auto_close_session">true</prop>

        </props>
    </property>
</bean>
<bean id="d2Dao" class="com.DaoImpl"
    autowire="byName">
    <property name="sessionFactory" ref="d2SessionFactory"></property>
</bean>

在我执行的运行时

Session session = this.sessionFactory.openSession() ;

即使dao是d2Dao，会话也始终对应于d1SessionFactory。不知道我在这里做错了什么。当我使用“AnnotationSessionFactoryBean”

时，相同的配置工作正常

帮助表示赞赏。

我得到的错误如下

多个LocalSessionFactoryBean不起作用
