我正在尝试实现以下内容:我需要在同一个事务中将两个不同的实体添加到数据库中。每个实体都有不同的 DAO 类和服务类。
public class InvoicesDAO {
@Autowired
protected SessionFactory sessionFactory;
public void save(Invoice object) {
Session session = SessionFactoryUtils.getSession(sessionFactory, false);
session.persist(object);
}
}
public class RequestsDAO {
@Autowired
protected SessionFactory sessionFactory;
public void save(Request object) {
Session session = SessionFactoryUtils.getSession(sessionFactory, false);
session.persist(object);
}
}
public class InvoicesService {
@Autowired
private InvoicesDAO invoicesDAO;
@Autowired
private RequestsDAO requestsDAO;
@Transactional
public void add(Invoice object) throws HibernateException {
invoicesDAO.save(object);
}
@Transactional
public void updateAndGenerate(Invoice object1, Request object2) throws HibernateException {
invoicesDAO.save(object1);
requestsDAO.save(object2);
}
}
配置:
<tx:annotation-driven transaction-manager="transactionManager" />
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:/hibernate.properties" />
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${hibernate.connection.driver_class}" />
<property name="url" value="${hibernate.connection.url}" />
<property name="username" value="${hibernate.connection.username}" />
<property name="password" value="${hibernate.connection.password}" />
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.ejl.butler.object.data" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
<prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop>
<prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop>
</props>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<context:annotation-config />
<context:component-scan base-package="com.service" />
<bean id="invoicesDao" class="com.dao.InvoicesDAO" />
<bean id="requestsDao" class="com.dao.RequestsDAO" />
控制器:
//***
/**
* Invoices access service
*/
@Autowired
private InvoicesService invoicesService;
// objects creation
invoicesService.updateAndGenerate(invoice, request);
//***
因此,当我尝试调用 updateAndGenerate 方法并在那里传递 object2 的无效值时 - 它会在不回滚 object1 的情况下失败。我该如何解决?谢谢
