Spring-Hibernate使用多个数据源/数据库

Question

我正在开发一个使用Spring MVC 3和Hibernate的Web应用程序

我想为我的Web应用程序使用2个数据源MySql和Oracle数据库,

我已经阅读了许多关于"spring-hibernate multiple datasource/database"的教程和解决问题的例子:

堆栈溢出

论坛春天

等等.

但是当我每次运行它时,配置只读取我的第一个数据库配置(MySql)并显示此错误Table 'db_prod.ksei_lookup_holiday' doesn't existdb.prod是我的第一个数据库(MySql)而KSEI_LOOKUP_HOLIDAY是我的第二个数据库(Oracle),

这是我的spring.xml

<tx:annotation-driven transaction-manager="transactionManager"/>
<tx:annotation-driven transaction-manager="transactionManagerSOAAPP"/>
<context:annotation-config />


<context:component-scan base-package="prod.support" />

<!-- Database MySql, Desktop -->

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/db_prod" />
    <property name="username" value="root" />
    <property name="password" value="shikamaru" />
</bean>

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration"></property>
    <property name="dataSource" ref="dataSource"></property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
            <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
    <property name="packagesToScan" value="prod.support.model.splatter" />
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager"
    p:sessionFactory-ref="sessionFactory">
</bean>

<!-- Database Oracle, Schema : SOAAPP -->

<bean id="dataSourceSOAAPP" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
    <property name="url" value="jdbc:oracle:thin:@localhost:1521:XE" />
    <property name="username" value="splatter" />
    <property name="password" value="shikamaru" />
</bean>

<bean id="sessionFactorySOAAPP"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration"></property>
    <property name="dataSource" ref="dataSource"></property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
    <property name="packagesToScan" value="prod.support.model.soaapp" />
</bean>

<bean id="transactionManagerSOAAPP"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager"
    p:sessionFactory-ref="sessionFactorySOAAPP">
</bean>

这是我的第一个数据库(MySql)的DAO实现

@Repository
@Qualifier(value="sessionFactory")
public class UserDaoImpl extends HibernateDaoSupport implements UserDao{

@Autowired
private UserDaoImpl(SessionFactory sessionFactory){
    setSessionFactory(sessionFactory);
}

这是我的第二个数据库(Oracle)的DAO实现

@Repository
@Qualifier(value="sessionFactorySOAAPP")
public class UpdateKSEIDaoImpl extends HibernateDaoSupport implements UpdateKSEIDao{

@Autowired
private UpdateKSEIDaoImpl(SessionFactory sessionFactorySOAAPP){
    setSessionFactory(sessionFactorySOAAPP);
}

任何帮助都会很愉快:)

Answer 1

问题是你用过

<property name="dataSource" ref="dataSource"></property>在sessionFactorySOAAPP。

你应该用过<property name="dataSource" ref="dataSourceSOAAPP"></property>
