Spring-Hibernate using multiple datasource/database

Question

I'm working on a web application that uses Spring MVC 3 and Hibernate

I want to use 2 datasource MySql and Oracle databases for my web application,

I've been read many tutorial and problem solving for "spring-hibernate multiple datasource/database" for example :

directjump2java.blogspot.com

stackoverflow

forum spring

and etc.

but when every single time I run it, the config just read my first database config (MySql) and show this error Table 'db_prod.ksei_lookup_holiday' doesn't exist db.prod is my first database(MySql) and KSEI_LOOKUP_HOLIDAY is my second database (Oracle),

this is my 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 -->

    <property name="username" value="root" />
    <property name="password" value="shikamaru" />

</bean>

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

this is my DAO Implementation for my first database (MySql)

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

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

this is my DAO Implementation for my second database (Oracle)

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

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

any help will be pleasure :)

Answer 1

The problem is that you have used

<property name="dataSource" ref="dataSource"></property> in sessionFactorySOAAPP .

You should have used <property name="dataSource" ref="dataSourceSOAAPP"></property>

Answer 2

如果选中“sessionFactorySOAAPP”，则下面的属性名称应为“dataSourceSOAAPP”，而不是“dataSource”。

Answer 3

this my configuration file:

<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>

Answer 4

@geoand is correct in the error he spotted. Other than that the context xml seems correct and works for me. However, for me, this only works if @qualifier is with the @Autowired.

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