我有一个spring integration hibernate应用程序。我的应用程序选择文件并根据数据库检查其条目。为此，我使用的是Hibernate。
我想禁用数据库中的某些行。我正在使用条件检索行。编辑一个字段并使用saveorupdateall方法。这根本不会改变我的数据库行！
以下是代码段
<bean id="dmsdbDetectionJob" class="com.polling.scheduler.job.DMSDBDetectionJob">
</bean>
<bean id="dmsdbDetectionJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="dmsdbDetectionJob" />
<property name="targetMethod" value="deleteDBMaster" />
<property name="concurrent" value="false" />
</bean>
<bean id="simpleTriggerDB" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="dmsdbDetectionJobDetail" />
<!-- <property name="cronExpression" value="1 * * * * ?" /> -->
<!-- <property name="cronExpression" value="0 0/1 * * * ?" /> -->
<property name="cronExpression" value="0 52 11 ? * *" />
</bean>
这在正确的时间点火。 deleteDBMaster方法调用此代码：
//get Document files not having any links
List<DocumentFile> strayFiles = documentDaoImpl.getStrayDocumentFiles();
try
{
if (strayFiles.size() > 0)
{
//delete
strayFiles = documentDaoImpl.softDelete(strayFiles, DocumentFile.class);
documentDaoImpl.saveOrUpdateAll(strayFiles);}
}...
softDelete方法使用泛型
@Override
public <T extends GenericEntity> List<T> softDelete(List<T> stray,
Class<T> clazz)
{
for (T tObj : stray)
{
clazz.cast(tObj).setActive(Constants.INACTIVE.getVal());
}
return stray;
}
当我调试时，我在saveOrUpdateAll（）方法中看到strayFiles列表中对象的active属性中的值已更改。 saveOrUpdateAll方法是：
@Override
public void saveOrUpdateAll(Collection<?> objects) throws DMSException {
try {
for (Object object : objects) {
getCrntSession().saveOrUpdate(object);
}
} catch (final HibernateException e) {
throw new DMSException("Exception while save or update All ", ErrorCode.BASE_DB_ERROR, e);
}
}
当调用saveorupdate时，hibernate不会记录任何查询。 db !!
中没有任何变化由于这是在spring集成中，我刚刚在方法中添加了@Transactional。我假设spring必须执行flush或commit。那是错的吗？即便如此，我应该看到查询正确吗？
请告诉我代码中的错误...
由于
EDIT ::
将我的软删除代码更改为以下内容。想到也许仿制药正在造成这种情况。
@Override
@Transactional
public void softDeleteDocumentFile(
List<DocumentFile> stray)
{
for (DocumentFile tObj : stray)
{
tObj.setActive(Constants.INACTIVE.getVal());
saveEntity(tObj);
}
}
仍然没有变化。行未更新。 Hibernate没有在控制台上打印更新查询!!
如果有人发现代码中有任何错误，请告诉我。

找到了问题的症结所在。根本不涉及交易。我错误地将updatable = false添加到我的实体类属性（活动）get访问器中。抱歉，添麻烦了。真的是一个非常基本的错误！向所有花时间在这上面的人致歉......
答案 1 :(得分：1)
session.saveOrUpdate（Object）方法只将任何临时对象转换为持久对象，意味着对象与当前的hibernate会话关联。当刷新当前的hibernate会话或者提交hibernate事务时，只会运行实际的查询来将对象数据存储到数据库中。
Hibernate saveOrUpdate（Object）的工作方式与上面的注释类似。我对Spring不太了解。 我希望上面的描述对你有用。
示例代码：Hibernate
Session session = sessionFactory.getCurrentSession();
session.setFlush(FlushMode.COMMIT);// Session will be flushed when transation.commit will be called
Transaction tx = session.beginTransaction();
session.saveOrUpdate(Object obj);
tx.commit();// this line will run query to map your object on database
OR
Session session = sessionFactory.getCurrentSession();
session.setFlush(FlushMode.MANUAL);// Session will be only ever flushed when session.flush() will be explicitely called by aaplication
Transaction tx = session.beginTransaction();
session.saveOrUpdate(Object obj);
session.flush();// this line will run query to map your object on database
tx.commit();

到目前为止您所写的内容似乎是您的Spring TransactionManagement配置错误。
如果您不想配置方面，一个简单的解决方案是使用Spring Framework TransactionTemplate
public class DMSDBDetectionJob {
private final TransactionTemplate transactionTemplate;
public DMSDBDetectionJob(PlatformTransactionManager transactionManager) {
Assert.notNull(transactionManager, "The 'transactionManager' argument must not be null.");
this.transactionTemplate = new TransactionTemplate(transactionManager);
// optional configuration of the Transaction like timeout
// this.transactionTemplate.setTimeout(30); // 30 seconds
}
public void deleteDBMaster() {
transactionTemplate.execute(new TransactionCallbackWithoutResult() {
protected void doInTransactionWithoutResult(TransactionStatus status) {
deleteDBMasterImpl();
}
});
}
private void deleteDBMasterImpl() {
List<DocumentFile> strayFiles = documentDaoImpl.getStrayDocumentFiles();
try
{
if (strayFiles.size() > 0)
{
//delete
strayFiles = documentDaoImpl.softDelete(strayFiles, DocumentFile.class);
documentDaoImpl.saveOrUpdateAll(strayFiles);
...
}
} catch (...) {...}
}
您的Spring配置至少应包含两个条目：
<!-- PlatformTransactionManager which are going to drive transaction-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- Instance of transaction template -->
<bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager" ref="transactionManager"></property>
</bean>
