我已成功使用自定义部署程序填充我的存储扩展表,现在我可以看到如果用户发布任何页面,我的记录将完美无缺。

现在我想处理Unpublishing部分,所以我写了自定义页面undeployer,请看下面的示例代码:

@SuppressWarnings({ "rawtypes" })
public void process(TransportPackage data) throws ProcessingException 
{
    ProcessorInstructions instructions = data.getProcessorInstructions();       

    try 
    {
        for (Iterator iterator = instructions.getArguments(); iterator.hasNext(); ) 
        {
            Object argument = iterator.next();
            if (argument instanceof PageKey) 
            {
              PageKey pageKey = (PageKey)argument;
              TCDURI pageMetaURI = new TCDURI(pageKey.getId().getPublicationId(), 1168231104576L, pageKey.getId().getItemId());
              PageMeta pageMeta = this.pageMetaHome.findByPrimaryKey(pageMetaURI.getPublicationId(), 
                (int)pageMetaURI.getItemId());
              if (pageMeta == null)
              {
                  DeploymentHandler.undeploy(pageMetaURI);
              }
              else
              {
                  PublishAction publishAction = new PublishAction();
                  publishAction.setAction("DEL");
                  long id = publishAction.getId();
                  PublishActionDAO publishActionDAO = (PublishActionDAO) StorageManagerFactory.getDefaultDAO("PublishAction");
                  publishAction = publishActionDAO.findByPrimaryKey(id);
                  if (publishAction == null) 
                  {
                      log.debug("FindByPrimaryKey: cannot retrieve object with primary key:" + id);
                  }
                  else
                  {
                      publishAction = publishActionDAO.update(publishAction);
                      log.debug("SearchPageUndeployer Updated bean -" + publishAction);                      
                  }
              }
            }
        }
    }
    catch (Exception e) 
    {
        throw new ProcessingException("SearchPageUndeployer: Could not undeploy page", e);
    }
    super.process(data);
}

在上面的代码中,您可以看到我正在尝试更新我的新存储扩展" PublishAction",但是当我尝试从我想要修改的记录的表中获取ID时,我总是将ID设为0,因为我无法从表中获取ID。

请建议在我的DAO中需要实现什么才能从表中获取需要更新的记录的ID。

感谢。

您可以在DAO中创建类似findByTCMURI的方法,以根据页面tcm uri搜索您的发布操作。代码将是这样的:

public PublishAction findByTCMURI(String tcmURI) throws StorageException {
    StringBuilder queryBuilder = new StringBuilder();
    queryBuilder.append("from PublishAction pa where pa.tcmuri = :tcmuri");

    Map<String, Object> queryParams = new HashMap<String, Object>();
    queryParams.put("tcmuri", tcmURI);

    return executeQuerySingleResult(queryBuilder.toString(), queryParams);
}

应该做的伎俩。 希望这会有所帮助。
