Я работаю над веб-приложением с Wicket, Spring и Hibernate, и у меня возникла проблема с обновлением записей.Я проверил, что метод saveOrUpdate вызывается, и что данные в объекте домена изменились.Вывод SQL, однако, не показывает, что в базу данных были внесены какие-либо изменения (например, UPDATE), а соответствующая запись не была обновлена.
Я думаю, что имеет больше смысла использовать update (), ноЯ saveOrUpdate () удается создать новые записи, но не обновляет их.Я проверил, что этот метод вызывается, и переданный UserVO содержит обновленные поля.Вот метод DAO:
public class SkuldwebDAOImpl extends HibernateDaoSupport implements SkuldwebDAO {
public void updateUser(UserVO userVO) {
getSession().saveOrUpdate(userVO);
}
}
Вот мой файл свойств:
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost/skuldweb_dev;AUTO=MULTI;CURSOR=READONLY
jdbc.username=
jdbc.password=
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.show_sql=true
hibernate.use_outer_join=true<br>
hibernate.cache.use_query_cache=true
hibernate.cache.use_second_level_cache=true
hibernate.cache.provider=org.hibernate.cache.HashtableCacheProvider<br>
hibernate.schemaUpdate=true
Вот бин sessionFactory в applicationContext.xml: <pre>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>

<prop key="use_outer_join">${hibernate.use_outer_join}</prop>
<prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop>
<prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop>
<prop key="hibernate.cache.provider_class">${hibernate.cache.provider}</prop>
<prop key="hibernate.connection.pool_size">10</prop>
<prop key="hibernate.connection.autocommit">true</prop>
<prop key="hibernate.jdbc.batch_size">1000</prop>
<prop key="hibernate.bytecode.use_reflection_optimizer">true</prop>
</props>
</property>
<property name="annotatedClasses">
<list>
<value>com.upbeat.app.skuldweb.domain.UserVO</value>
<value>com.upbeat.app.skuldweb.domain.UserLevelVO</value><br>
</list>
</property>
<property name="schemaUpdate" value="${hibernate.schemaUpdate}"/>
</bean>
Надеемсяодин из вас может мне помочь.
Обновлено Вот некоторая информация из журнала (onSubmit () выделяет эти записи в журнале - последняя запись должна быть, когда запрос обрабатываетсяперенаправлен на другую страницу (после обновления записи).
