liferay-rest-consumer

This example liferay application is consuming REST service from https://github.com/sammso/simple-jersey (so you need that project too).

Configure address of this REST service to your portal-ext.properties.

rest-consumer-portlet.target=http://localhost:8080/simple-jersey

It is example how to use ServiceBuilder to consume REST services.

If you want to use this with OAuth authentication please try:

Examples:

Integrating to WebContent

You can also use create Service from web content template to fetch web-content:

#set ($noteService = $utilLocator.findUtil("rest-consumer-portlet","org.liferay.portlet.restconsumer.service.NoteLocalService"))

#set ($list = $noteService.findNotes())

<h1>Portlet Rest integration for Web content</h1>

<table>
	<thead>
		<tr><th>ID</th><th>Title</th><th>Body</th></tr>
	</thead>
	<tbody>

#foreach( $note in $list )
    <tr><td>$note.getId()</td><td>$note.getTitle()</td><td>$note.getBody()</td></tr>
#end

	</tbody>
</table>

Using through JSON WS API

To test you can just Copy paste to browser:

http://<your domain and port>/api/jsonws/invoke?cmd=<json here>

All the notes:

{“/rest-consumer-portlet.note/find-notes":{}}

Limit the fields:

{"$note[id,title]=/rest-consumer-portlet.note/find-notes":{}}

Combine

{"$user[userId]=/rest-consumer-portlet.note/get-current-user":
	{
		“$roles[roleId,name]=/role/get-user-roles”:
			{“@userId”:”$user.userId”}
	}
}

Build

To build you need maven or Liferay Developer Studio

mvn package should be enough and then /rest-consumer/rest-consumer-portlet should contain file to be deployed to Liferay.
