Hibernate saveorupdateall沒有保存不更新

Question

我有一個spring集成的hibernate應用程序。 我的應用程序選擇文件並根據數據庫檢查其條目。 為此，我正在使用Hibernate。

我想禁用數據庫中的某些行。 我正在使用條件檢索行。 編輯一個字段並使用saveorupdateall方法。 這根本不會改變我的數據庫行！

以下是代碼片段

  <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>

這在正確的時間點火。 deleteDBMaster方法調用此代碼：

        //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;
}

當我調試時，我在saveOrUpdateAll（）方法中看到strayFiles列表中對象的active屬性中的值已更改。 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);
    }
} 

調用saveorupdate時，hibernate不會記錄任何查詢。 db中沒有任何變化!!

由於這是在spring集成中，我剛剛在方法中添加了@Transactional。 我假設spring必須執行flush或commit。 那是錯的嗎？ 即便如此，我應該看到查詢正確？

請讓我知道代碼中有什么問題......

謝謝

編輯：：

將我的softdelete代碼更改為以下內容。 想到也許仿制葯正在造成這種情況。

    @Override
@Transactional
public void softDeleteDocumentFile(
        List<DocumentFile> stray)
{
    for (DocumentFile tObj : stray)
    {
        tObj.setActive(Constants.INACTIVE.getVal());
        saveEntity(tObj);
    }
}

仍然沒有變化。 行未更新。 Hibernate沒有在控制台上打印更新查詢!!

如果有人發現代碼中有任何錯誤，請告訴我。

嘗試使用硬編碼的id。 使用更新而不是保存。 但仍然是相同的結果，沒有更新查詢，因此行沒有變化！

Answer 1

找到了問題的症結所在。 根本不涉及交易。 我錯誤地將updatable = false添加到我的實體類屬性（活動）get訪問器中。 抱歉，添麻煩了。 真的是一個非常基本的錯誤！ 向所有花時間在這上面的人致歉

Answer 2

session.saveOrUpdate（Object）方法只將任何臨時對象轉換為持久對象，意味着對象與當前的hibernate會話關聯。 當刷新當前的hibernate會話或提交hibernate事務時，只會運行實際的查詢來將對象數據存儲到數據庫中。

Hibernate saveOrUpdate（Object）的工作方式與上面的注釋類似。 我對Spring不太了解。 我希望上面的描述對你有用。

示例代碼：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();

謝謝

Answer 3

到目前為止您所寫的內容似乎是您的Spring TransactionManagement配置錯誤。

如果您不想配置方面，一個簡單的解決方案是使用Spring Framework TransactionTemplate的編程方法

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配置至少應包含兩個條目：

<!-- 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>
