Access catalogVersionService from Groovy class

[former_member633554]

Hi all , i'm trying to access the catalogversionservice through groovy, yet this throws up errors. It works fine if it's not in a class.

The error i get is Script execution has failed [reason: java.lang.NullPointerException: Cannot invoke method getCatalogVersion() on null object]

 import de.hybris.platform.catalog.model.CatalogVersionModel;
 import de.hybris.platform.catalog.model.CatalogModel;
 import de.hybris.platform.core.model.product.ProductModel;
 import de.hybris.platform.product.ProductService;
 import de.hybris.platform.catalog.CatalogVersionService;
 import de.hybris.platform.catalog.model.classification.ClassAttributeAssignmentModel;
 import de.hybris.platform.catalog.model.classification.ClassificationClassModel;
 import de.hybris.platform.classification.features.*;
 
 public class MainClass
 {
   
  def outputData()
   {
     CatalogVersionModel catalogVersion=catalogVersionService.getCatalogVersion("Maincat", "Staged");
  ProductModel product1 = productService.getProductForCode(catalogVersion,"PROD_1");
   
   }
 }
 
 new MainClass().outputData()

catalogVersionService is not in scope. It belongs to the implicit script class and is therefore not accessible from an instance of MainClass

You could do something like this to pass the catalogVersionService in when you construct the instance of MainClass

 public class MainClass {
   def catalogVersionService
   def productService
    
   def outputData() {
     def catalogVersion = catalogVersionService.getCatalogVersion('Maincat', 'Staged')
     def product1 = productService.getProductForCode(catalogVersion, 'PROD_1')
     println product1.name
   }
 }
  
 new MainClass(catalogVersionService: catalogVersionService, productService: productService).outputData()

This also works from within a method in a class.

  CatalogVersionService catalogVersionService = (CatalogVersionService) Registry.getApplicationContext().getBean("catalogVersionService");
   CatalogVersionModel catVersion = catalogVersionService.getCatalogVersion("Maincat", "Staged");

Hi , While using groovy , you can access the spring beans directly by their bean id. In your case , rather using defaultCatalogVersionService would probably do the trick.

Hi,

Have you checked this document? https://help.hybris.com/6.4.0/hcd/8bec04a386691014938a9996a977d07f.html

Have you tried to get catalogVersionService by:

 catalogVersionService = spring.getBean "catalogVersionService"

?
