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，

我已经阅读了很多关于“spring-hibernate multiple datasource/database”的教程和问题解决方案 例如：

directjump2java.blogspot.com

stackoverflow

forum spring

等等

但是当我每次运行它时，配置只是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 exist db.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 -->

    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">

</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);
}

任何帮助都会很高兴:)

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>

Answer 2

如果您选中“sessionFactorySOAAPP”，那么下面的属性名称应该是“dataSourceSOAAPP”而不是“dataSource”。

Answer 3

这是我的配置文件：

<bean id="dataSource"
      class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url"
              value="jdbc:mysql://localhost:3306/gl?characterEncoding=UTF-8" />
    <property name="username" value="root" />
    <property name="password" value="2238295" />
</bean>



<bean id="mainDataSource"
      class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url"
              value="jdbc:mysql://localhost:3306/gl_main?characterEncoding=UTF-8" />
    <property name="username" value="root" />
    <property name="password" value="2238295" />
</bean>

<!-- Hibernate 4 SessionFactory Bean definition -->
<bean id="sfAccounting"
      class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.gl.domain.accounting" />
    <property name="hibernateProperties">

            <prop key="hibernate.show_sql">false</prop>

    </property>
</bean>

    </property>
</bean>

Answer 4

@geoand 在他发现的错误中是正确的。除此之外，上下文 xml 似乎是正确的并且对我有用。 但是，对我来说，这仅在 @qualifier 与 @Autowired 一起使用时才有效。

@Repository
public class BusinessDaoImpl implements BusinessDao
{
@Autowired
@Qualifier(value="sessionFactory")
SessionFactory sessionFactory;
