public class DefaultContentDao extends VersionedHibernateObjectDao<ContentEntityObject> implements ContentDaoInternal
Generic DAO for hibernate objects. Takes care of indexing and unindexing, and setting creation and update times for objects.

For this reason, you should always do object CRUD through the DAO, you shouldn't trust Hibernate to do it for you: Hibernate will save the object, but skip the additional stuff the DAO does.

Subclasses will need to implement the HibernateObjectDao.getPersistentClass() method to return the class that the DAO is serving: that way getByClassId() will perform correctly.

Subclasses should also override HibernateObjectDao.updateModificationData(EntityObject) if they want to perform any additional modifications on objects that are being saved through the DAO. Just remember to call super. (updateModificationData will not be called if an object is saved through #saveRawEntity(EntityObject))

    • getPersistentClass

      public Class<ContentEntityObject> getPersistentClass()
      Specified by:
      getPersistentClass in class HibernateObjectDao<ContentEntityObject>

    • getById

      public ContentEntityObject getById(long id)
      Specified by:
      getById in interface ContentDao

    • getLatestContentCount

      public int getLatestContentCount()
      Specified by:
      getLatestContentCount in interface ContentDao

    • getLatestOrderedWikiContentFromContentId

      public List<ContentEntityObject> getLatestOrderedWikiContentFromContentId(long startContentId, int maxRows)
      Specified by:
      getLatestOrderedWikiContentFromContentId in interface ContentDao
      Parameters:
      startContentId - start content id
      maxRows - max rows
      Returns:
      the latest versions of wiki content within the specified bounds

    • getOrderedXhtmlContentFromContentId

      public List<ContentEntityObject> getOrderedXhtmlContentFromContentId(long startContentId, int maxRows)
      Description copied from interface: ContentDao

      This is for internal use only, Do not rely on it as a public API. This is used to retrieve batches of data during migration or upgrades.

      Warning: You will want to keep maxRows as small as possible because a list of CEO can be a very memory hungry structure. A good example is the default used in content migration which is 500.

      Specified by:
      getOrderedXhtmlContentFromContentId in interface ContentDao
      Returns:
      a list ordered by id of all the ContentEntityObjects with XHTML formatted bodies.

    • updateModificationData

      protected void updateModificationData(ContentEntityObject objectToSave)
      This method overrides the default behaviour which is to get the current user from a thread local and to set the last updated time to the current time. We do not want this for the migration.

      We do however need to set the creationdate if it is not set.

      Overrides:
      updateModificationData in class ConfluenceHibernateObjectDao<ContentEntityObject>
      Parameters:
      objectToSave - the object that is about to be saved
