Liferay module listener : Unable to get who made a change to the model

I have to create custom auditing for the User model to track by whom the user has been deleted. I have tried to create a Liferay module listener for the User model, but I am not able to get the detail by whom the user is being deleted.

Is there any way to get details about who made a change to the User model in Liferay module listener?

My Liferay environment detail

package com.test.useraudit.modellistner;

import org.osgi.service.component.annotations.Component;

import com.liferay.portal.kernel.exception.ModelListenerException;
import com.liferay.portal.kernel.model.BaseModelListener;
import com.liferay.portal.kernel.model.ModelListener;
import com.liferay.portal.kernel.model.User;

@Component(
    immediate = true,
    service = ModelListener.class
)

public class CustomUserModelListner extends BaseModelListener<User>{
    @Override
    public void onBeforeRemove(User user) throws ModelListenerException{
        System.out.println("In onBeforeRemove method");
        System.out.println("User detail :");
        System.out.println(user);
        super.onBeforeRemove(user);
    }

    @Override
    public void onAfterRemove(User user) throws ModelListenerException{
        System.out.println("In onAfterRemove method");
        System.out.println("User detail :");
        System.out.println(user);
        super.onAfterRemove(user);
    }
}
Solution

  • Yes it's possible.

    There's an implicit thread local variable called ServiceContext that contains the calling context details.

    Sample:

       @Override
    public void onBeforeRemove(User user) throws ModelListenerException{
            ServiceContext serviceContext =
                 ServiceContextThreadLocal.getServiceContext();

            System.out.println("Calling user:" + serviceContext.getUserId());
    }
