Liferay is easy: Change Permission of a File/Document by Groovy in Lilferay

In the previous blog we Change the permission of a file to guest programmatically in this blog we change the permission by groovy script.

So Lets start this:-
First go to control panel ->Server Administration->Script->Select Groovy and paste this:-

	import java.util.ArrayList
	import java.util.Iterator
	import java.util.List
	import java.util.ListIterator

	import com.liferay.portal.service.ResourcePermissionLocalServiceUtil
	import com.liferay.portal.service.RoleLocalServiceUtil
	import com.liferay.portal.model.ResourceConstants
	import com.liferay.portal.model.ResourcePermission
	import com.liferay.portal.model.Role
	import com.liferay.portal.model.RoleConstants
	import com.liferay.portal.service.ServiceContext;
	import com.liferay.portlet.documentlibrary.model.*;
	import com.liferay.portlet.documentlibrary.service.*;
	import com.liferay.portlet.documentlibrary.service.persistence.*;
	import com.liferay.portal.security.permission.ActionKeys

	try {

	// Replace companyId and fileEntryId
	long companyId = 10154
	long groupId = 10181
	start = -1
	end = -1

	Role guestRole = RoleLocalServiceUtil.getRole(companyId, RoleConstants.GUEST)
	String resourceName = DLFileEntry.class.getName()
	def keys = new String[1]
	keys[0] = ActionKeys.VIEW

	def files = DLFileEntryLocalServiceUtil.getDLFileEntries(start, end)
	println('>> files found:'+ files.size())
	for( i=0; i<files.size();i++){

	def file = files[i]
	if(file.getGroupId()==groupId){
	String fileEntryId = file.getFileEntryId()

	if (!ResourcePermissionLocalServiceUtil.hasResourcePermission(companyId, resourceName, ResourceConstants.SCOPE_INDIVIDUAL, fileEntryId, guestRole.getRoleId(), ActionKeys.VIEW)) {
	ResourcePermissionLocalServiceUtil.setResourcePermissions(companyId, DLFileEntry.class.getName(), ResourceConstants.SCOPE_INDIVIDUAL, fileEntryId, guestRole.getRoleId(), keys)
	out.print(",member");
	}
	out.println(" ");
	}
	}

	}catch (e) {
	out.println("Error = " + e.getMessage());
	}
