我在netbeans中实现了spring和hibernate注释。当我尝试将数据保存在数据库中时,它不会发生。当我从netbeans启动应用程序但未能在其中存储数据时,将创建表。
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.apache.derby.jdbc.ClientDriver"/>
<property name="url" value="jdbc:derby://localhost:1527/seed"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="annotatedClasses">
<list>
<value>com.vaannila.domain.User</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.DerbyDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
dao class:
@Repository("userDao")
public class UserDAOImpl implements UserDAO {
@Autowired
private SessionFactory sessionFactory;
/*public void setSessionFactory(SessionFactory sessionFactory) {
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}*/
@Override
public void saveUser(User user) {
sessionFactory.getCurrentSession().saveOrUpdate (user);
}
@Override
@SuppressWarnings("unchecked")
public List<User> listUser() {
return (List<User>) sessionFactory.getCurrentSession().
createCriteria ( User.class ).list();
}
}
服务类:
@Service("userService")
@Transactional(propagation=Propagation.SUPPORTS, readOnly=true)
public class UserServiceImpl implements UserService {
@Autowired
private UserDAO userDAO;
@Override
public void saveUser(User user) {
userDAO.saveUser(user);
}
@Override
@SuppressWarnings("unchecked")
public List<User> listUser() {
return userDAO.listUser();
}
}
请帮帮我。

问题是您使用的交易在服务中被标记为回滚(readOnly)!
因此,您需要将@Transaction(readOnly=false)
添加到您的控制器或服务方法或dao,以触发项目的商店操作。
例如:
@Transactional(propagation=Propagation.SUPPORTS, readOnly=true)
public class UserServiceImpl implements UserService {
...
//Do not role back this transaction
@Transactional(propagation=Propagation.SUPPORTS, readOnly=false)
@Override
public void saveUser(User user) {
userDAO.saveUser(user);
}
}
@See Spring Reference: Chapter 10.5.6 Using @Transactional形成一些细节
