事件监听器休眠 5
EventListener Hibernate 5
我正在使用 Hiberante 5 和 Spring 4.2.3。我找不到将 eventListener 添加到 SessionFactory 范围的方法。我只需要在 hibernate 持久化一个对象之前设置一个日期。我在 spring.xml
中定义了 sessionFactory
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mappingResources">
<list>
<value>com/hibernate/mapping/User.hbm.xml</value>
<value>com/hibernate/mapping/PublicKey.hbm.xml</value>
<value>com/hibernate/mapping/File.hbm.xml</value>
<value>com/hibernate/mapping/Url.hbm.xml</value>
<value>com/hibernate/mapping/Role.hbm.xml</value>
<value>com/hibernate/mapping/Operation.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">validate</prop>
<prop key="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
<prop key="hibernate.c3p0.min_size">5</prop>
<prop key="hibernate.c3p0.max_size">50</prop>
<prop key="hibernate.c3p0.timeout">100</prop>
<prop key="hibernate.c3p0.max_statements">50</prop>
<prop key="hibernate.c3p0.idle_test_period">3000</prop>
<prop key="hibernate.c3p0.validate">true</prop>
</props>
</property>
</bean>
而且我有我的 GenericDAOImpl,可以在其中获取此 sessionFactory:
public abstract class GenericDAOImpl <T, PK extends Serializable> implements GenericDAO<T, PK> {
private SessionFactory sessionFactory;
/** Domain class the DAO instance will be responsible for */
protected Class<T> type;
@SuppressWarnings("unchecked")
public GenericDAOImpl() {
Type t = getClass().getGenericSuperclass();
ParameterizedType pt = (ParameterizedType) t;
type = (Class<T>) pt.getActualTypeArguments()[0];
}
@SuppressWarnings("unchecked")
public PK create(T o) {
return (PK) getSession().save(o);
}
public T read(PK id) {
return (T) getSession().get(type, id);
}
public void update(T o) {
getSession().update(o);
}
public void delete(T o) {
getSession().delete(o);
}
@SuppressWarnings("unchecked")
public List<T> getAll() {
return getSession().createCriteria(type).list();
}
protected Session getSession() {
return sessionFactory.getCurrentSession();
}
// getters and setters
}
我见过几种方法,但其中一些不适用于 Hiberante 5(如 Integrator
)。而且我找不到通过 xml 添加此 eventListener 或仅在 sessionFactory 范围内添加代码的方法。我找到了如何使用 sessionFactory.withOptions().eventListeners(listeners);
添加到会话范围
谢谢!
最后,太简单了,我找到了一种通过 xml 添加拦截器的方法,只需添加:
<property name="entityInterceptor">
<bean class="com.xxx.xxx.className"></bean>
</property>
我在 post 中找到了这个:
