如何在Component Presentation存储扩展中获取Component对象

Question

我正在尝试在Tridion 2011中编写存储扩展,我将在其中进行扩展JPAComponentPresentationDAO和实现ComponentPresentationDAO.

public void create(ComponentPresentation itemToCreate, ComponentPresentationTypeEnum componentPresentationType) throws StorageException 
{
    super.create(itemToCreate,componentPresentationType);   
    String tcmURI = Integer.toString(itemToCreate.getComponentId());
    Component compObject // I want Component object to get the schema ID 
    PublishActionDAO publishActionDAO = (PublishActionDAO) StorageManagerFactory.getDefaultDAO("PublishAction");
    PublishAction publishAction = new PublishAction();
    publishAction.setAction("ADD"); 
    publishAction.setTcmUri(tcmURI);
    publishActionDAO.store(publishAction);
}

在上面的示例代码中,我想itemToCreate.getComponentId()在我获取组件ID的地方使用Component对象,这样我就可以将一些有用的细节传递给我的实体类,该实体类将该数据存储在我的数据库表中.

您将能够获得ComponentMeta从ItemMeta继承的Schema Id .首先,你需要得到ItemDAO来自StorageManagerFactory然后findByPrimaryKey将给予ComponentMeta.这仅适用于super.create将组件持久保存到代理db之后.试试吧.

示例代码段:

ItemDAO item = (ItemDAO) StorageManagerFactory.getDAO(pubid,StorageTypeMapping.COMPONENT_META);
ComponentMeta meta = (ComponentMeta) item.findByPrimaryKey(pubid,compid);
int schemaID = meta.getSchemaId() ;

注意:您需要从itemToCreate tcmURI传递pubid,compid
