java - JPA (Hibernate) and custom table prefixes

Question

Is it possible to override table names in JPA/Hibernate in order to add a common prefix for all project entities? For instance to be able to prefix all JBPM 5 tables by "JBPM5_" prefix.

Example for the accepted answer:

public class JBPM5NamingStrategy extends ImprovedNamingStrategy {
   public String classToTableName(String className) {
      return StringHelper.unqualify(className);
   }
   public String propertyToColumnName(String propertyName) {
      return propertyName;
   }
   public String tableName(String tableName) {
      return "JBPM5_" + tableName;
   }
   public String columnName(String columnName) {
      return columnName;
   }
   public String propertyToTableName(String className, String propertyName) {
      return "JBPM5_" + classToTableName(className) + '_'
         + propertyToColumnName(propertyName);
   }
}

Answer 1

One way to rename all tables at once, is to implement your own namingStrategy (implementation of org.hibernate.cfg.NamingStrategy).

The NamingStrategy used is specified within persistence.xml by

<property name="hibernate.ejb.naming_strategy"
          value="com.example.MyNamingStrategy" />
