How to get page id in Confluence programmatically?

[George Lewe (Lewe)]

Here is how I was able to resolve this:

import com.atlassian.confluence.core.ContentEntityObject;
import com.atlassian.confluence.content.render.xhtml.ConversionContext;
...

public class MyClass (...
   ...
   public String execute(...
      ContentEntityObject contentEntityObject = conversionContext.getEntity();
      System.out.println("pageId : " + contentEntityObject.getId());
      ...
   }
}

Hi, George!

Could you show the whole code of page id execution, please? 

[George Lewe (Lewe)]

Here is a template that might help:

public String execute(Map<String, String> map, String body, ConversionContext conversionContext) throws MacroExecutionException {

   pageBuilderService.assembler().resources().requireWebResource("com.xxx.confluence.plugins.myplugin:webresources");
   AttachmentManager attachmentManager = (AttachmentManager) ContainerManager.getComponent("attachmentManager");

   //
   // Get page ID
   //
   ContentEntityObject contentEntityObject = conversionContext.getEntity();
   Long contentId = contentEntityObject.getId();
   String pageId = contentId.toString();

   //
   // Get Base URL
   //
   BootstrapManager bootstrapManager = (BootstrapManager) ContainerManager.getComponent("bootstrapManager");
   String baseUrl = bootstrapManager.getBaseUrl();

   //
   // Build output and return it
   //      
   String output = "<p>Page ID: " + pageId + "</p><p>Base URL: " + baseUrl + "</p>";
   return output;
}

George, thank you very much! you are my hero!

Hi Matti,

did you figure this one out? I have the same challenge, getting the page ID in a plugin macro. How can I retrieve it in the Java class file?

Best regards,
George

Edit: Sorry, this should have been a reply to the first answer.

The answer to that depends on where you are starting from!  Imagine asking someone "how do I get to London?".  When they don't know where you are now.

Where is your code running basically?  A script?  A user macro?  A search result function? An add-on that's adding some form of interface (like the admin fuctions)?  Another way to ask that is "in what context"?

[Matti Kiviharju]

To the macro Java code:

<macro name='grid-user-timesheet' class='${project.groupId}.GridEditorUserMain' key='agile-application-stack-user'>
        <description>Creates a editable Timesheet to Confluence Page.</description>
        <resource type="velocity" name="help" location="templates/extra/editor/grideditoruser-help.vm">
            <param name="help-section" value="advanced"/>
        </resource>        
    </macro>

So, this is an add-on for Confluence that provides a macro?

From memory, there should be a "context" variable, which gets an id via context.entity.id

[Matti Kiviharju]

Yes this is an Add-on for Confluence.

Can it get with this?

That looks right to me.  Not tested it, but it should do it.
