Class AlterTableNameClassTransformer

java.lang.Object

org.broadleafcommerce.common.extensibility.jpa.copy.AbstractClassTransformer

org.broadleafcommerce.common.extensibility.jpa.convert.AlterTableNameClassTransformer

All Implemented Interfaces:

javax.persistence.spi.ClassTransformer, BroadleafClassTransformer, org.springframework.beans.factory.InitializingBean

public class AlterTableNameClassTransformer
extends AbstractClassTransformer
implements BroadleafClassTransformer

This BroadleafClassTransformer changes the name of the Table for an entity before Hibernate sees it. This allows us to safely change/alter the names of Tables for entities on patch releases.

Example of changing the Table name of Product to "BLC_ALTER_PRODUCT"

In applicationContext.xml

```xml ```

NOTE :* This will add a new table in the database and does *NOT* change the name of existing tables in a database.
