Question

这是我的sessionFactory配置。

<beans:bean id="sessionFactory"
            class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <beans:property name="dataSource" ref="dataSource" />
    <beans:property name="packagesToScan">
        <beans:list>
            <beans:value>package</beans:value>
        </beans:list>
    </beans:property>
    <beans:property name="hibernateProperties">
        <beans:props>
            <beans:prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect
                </beans:prop>
            <beans:prop key="hibernate.hbm2ddl.auto">update</beans:prop>
            <beans:prop key="hibernate.show_sql">false</beans:prop>
        </beans:props>
    </beans:property>
</beans:bean>
<beans:bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
            destroy-method="close">
    <beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <beans:property name="url"
                value="jdbc:mysql://localhost:3306/msell" />
    <beans:property name="username" value="root" />
    <beans:property name="password" value="" />
    <beans:property name="initialSize" value="10" />
    <beans:property name="maxActive" value="5" />
    <beans:property name="maxWait" value="5000" />
    <beans:property name="testOnBorrow" value="true"/>
</beans:bean>
<beans:bean id="transactionManager"
            class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <beans:property name="sessionFactory" ref="sessionFactory" />
</beans:bean>
<tx:annotation-driven mode="aspectj"
            transaction-manager="transactionManager" />
<beans:bean id="sessionFactorySports"
            class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <beans:property name="dataSource" ref="dataSourceSports" />
    <beans:property name="packagesToScan">
        <beans:list>
            <beans:value>package</beans:value>
        </beans:list>
    </beans:property>
    <beans:property name="hibernateProperties">
        <beans:props>
            <beans:prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect
                    </beans:prop>
            <beans:prop key="hibernate.hbm2ddl.auto">update</beans:prop>
            <beans:prop key="hibernate.show_sql">false</beans:prop>
        </beans:props>
    </beans:property>
</beans:bean>
<beans:bean id="dataSourceSports" class="org.apache.commons.dbcp.BasicDataSource"
            destroy-method="close">

    <beans:property name="password" value="" />
    <beans:property name="initialSize" value="10" />
    <beans:property name="maxActive" value="5" />
    <beans:property name="maxWait" value="5000" />
    <beans:property name="testOnBorrow" value="true"/>
</beans:bean>
<beans:bean id="transactionManagerSports"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <beans:property name="sessionFactory" ref="sessionFactorySports" />
</beans:bean>
<tx:annotation-driven mode="aspectj"
        transaction-manager="transactionManagerSports" />

我尝试过像下面这样注入sessionFactorySports。

@Autowired(required=false)
@Qualifier(value="sessionFactorySports")
SessionFactory sessionFactory;

但仍然只会注入原始的sessionFactory对象。配置有什么问题？为什么sessionFactorySports没有注入？

编辑1：

我尝试将第一个sessionFactory名称更改为sessionFactoryFashion.But现在我得到了＃34;没有定义类型为[org.hibernate.SessionFactory]的限定bean：期望的单个匹配bean但找到2：sessionFactoryFashion， sessionFactorySports＆＃34;这个错误

Answer 1

不应该是@Qualifier（“sessionFactorySports”）??

Answer 2

如果您打算使用多个数据源，那么正确的方法是拥有多个数据源而不是sessionfactory。

您可以通过使用或实现org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource来实现此目的。

你可以看看这个

dynamic-datasource-routing

spring和hibernate中的多个数据库
