liferay indexer hook

post processor indexer HookIndexer hook implements a post processing system on top of the existing indexer.

For example go to Users and Organizations and search based on type.

You wont get the result based on type.

To achieve this just follow the below steps.

Step 1 :

Create a liferay project and choose plugin type as hook and finish.

Step 2 :

Modify in liferay-hook.xml

<?xml version="1.0"?>

<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.1.0//EN" "http://www.liferay.com/dtd/liferay-hook_6_1_0.dtd">

<hook>

<indexer-post-processor>

<indexer-class-name>com.liferay.portal.model.Organization</indexer-class-name>

<indexer-post-processor-impl>com.javaeasyforu.MyCustomPostIndexer</indexer-post-processor-impl>

</indexer-post-processor>

</hook>

Step 3 :

create a package and java class

docroot/WEB-INF/src  ---->create a class as MyCustomPostIndexer

package com.javaeasyforu;

import com.liferay.portal.kernel.search.BaseIndexerPostProcessor;

import com.liferay.portal.kernel.search.Document;

import com.liferay.portal.kernel.search.Field;

import com.liferay.portal.model.Organization;

public class MyCustomPostIndexer extends BaseIndexerPostProcessor 

{

public void postProcessDocument(Document document, Object object)throws Exception {

  Organization orgEntity = (Organization) object;

  String indexerOrgTitle = null;

  try 

  {

    indexerOrgTitle = orgEntity.getType();

  }

  catch (Exception e) 

  {

    e.printStackTrace();

  }

  if (indexerOrgTitle.length() > 0)

  {

    document.addText(Field.TITLE, indexerOrgTitle);

  }

 }

}

Step 4 : Right click on project and deploy

Now go to control panel and click on Users and Organizations

Step 5 :

Search for Type and see the result

Note : It will effect only for new and update records but not for existing records. So edit for some organization and check the result.

Key Point :

Eclipse is not opening properly

# A fatal error has been detected by the Java Runtime Environment 

#

# SIGSEGV (0xb) at pc=0x00007f8e88aaa2a1, pid=7607, tid=140252668163840

Solution: After extracting eclipse you have file called config.ini inside configuration folder. Go there and add the below line at the end

org.eclipse.swt.browser.DefaultType=mozilla

difference between hook and ext

Hook                                                          EXT

Hot Deployable                                                    Not Hot Deployable

No need to Restart the server                              Need to restart the server

Maintenance is Easy                                           Maintenance is difficult

Not overriding code directly                                It will replace the code directly

Undoing is easy                                                   Undoing is difficult

Note : We can deploy only one ext plugin per Liferay installation.

Key Point : To avoid multiple submit in form submission when it got refresh give the below line in  liferay-portlet.xml

<action-url-redirect>true</action-url-redirect>

Liferay Custom Icons

In Liferay Search Container if you want to call your own image you can define as

<liferay-ui:search-container-column-text name="Cancel">

          <liferay-ui:icon image="my-custom-icon"  src="/PortletName/images/cancel.png" />

</liferay-ui:search-container-column-text>

copy your image in images folder and provide the path.

Key Point : If you want to reuse your custom portlet more than one time please give the below line in liferay-portlet.xml 

<instanceable>true</instanceable>
