Kaleo Workflow integration custom portlet

先在自己portlet  建立一個service.xml  以下的欄位可供參考，
建立好後即可build-service。
紅色文字部分是參考到database的 WorkflowInstanceLink 資料表


service.xml


<column name="resourcePrimKey" type="long"></column>
<column name="version" type="int"></column>
<column name="title" type="String"></column>
<column name="content" type="String"></column>
<column name="description" type="String"></column>
<column name="priority" type="int"></column>
<column name="status" type="int"></column>
<column name="statusByUserId" type="long"></column>
<column name="statusByUserName" type="String"></column>
<column name="statusDate" type="Date"></column>

<!-- Order -->

<order by="desc">
<order-column name="modifiedDate" />
</order>
<finder name="R_S" return-type="Collection">
<finder-column name="resourcePrimKey"></finder-column>
<finder-column name="status"></finder-column>
</finder>
<reference package-path="com.liferay.portal" entity="WorkflowInstanceLink"></reference>

=====================================================================

接下來 在 Liferay-portlet.xml 中，加入紅色部分<workflow-handler> 的tag，中間包夾的是workflowHandler的JAVA類別路徑。
請自行創建  class  並extends BaseWorkflowHandler ，並orverride 三個 abstract method。


Liferay-portlet.xml

<portlet>

<portlet-name>WorkflowCustom</portlet-name>

<icon>/icon.png</icon>

<workflow-handler>com.xxx.xxx.portlet.ArticleWorkflowHandler</workflow-handler>

<header-portlet-css>/css/main.css</header-portlet-css>

<footer-portlet-javascript>/js/main.js</footer-portlet-javascript>

<css-class-wrapper>WorkflowCustom-portlet</css-class-wrapper>

</portlet>

您需要擴展com.liferay.portal.kernel.workflow.BaseWorkflowHandler

public class ArticleWorkflowHandler extends BaseWorkflowHandler {

public static final String CLASS_NAME = Demo.class.getName();

@Override

public String getClassName() {

// TODO Auto-generated method stub

return CLASS_NAME;

}

@Override

public String getType(Locale locale) {

// TODO Auto-generated method stub

return LanguageUtil.get(locale, "model.resource." + CLASS_NAME);

}

@Override

public Object updateStatus(int status, Map<String, Serializable> workflowContext)

throws PortalException, SystemException {

long userId = GetterUtil.getLong((String) workflowContext.get(WorkflowConstants.CONTEXT_USER_ID));

        long resourcePrimKey = GetterUtil.getLong((String) workflowContext.get(WorkflowConstants.CONTEXT_ENTRY_CLASS_PK));

        ServiceContext serviceContext = (ServiceContext) workflowContext.get("serviceContext");

        return DemoLocalServiceUtil.updateStatus(userId, resourcePrimKey,status, serviceContext);

}

}

====================================================================

Now you need to implement one method called updateStatus() in you LocalServiceImpl class. which will return object of your model class.

public class DemoLocalServiceImpl extends DemoLocalServiceBaseImpl
{
  public Demo updateStatus(long userId, long resourcePrimKey, int status,ServiceContext serviceContext)   
  {
    User user = userPersistence.findByPrimaryKey(userId);
    Date now = new Date();
    // Article
    Demo dempObj = null;
    dempObj.setStatus(status);
    dempObj.setStatusByUserId(user.getUserId());
    dempObj.setStatusByUserName(user.getFullName());
    dempObj.setStatusDate(serviceContext.getModifiedDate(now));
    demoPersistence.update(dempObj, false);
    if (status != WorkflowConstants.STATUS_APPROVED)
    {
      return dempObj;
    }
    return dempObj;
  }
}
=================================================================================


Now Deploy service and portlet you will find out your asset in control panel as showing below .now you can apply any definition on that.
