Question

The Hibernate Search documentation for using a ResultTransformer gives the following example:

org.hibernate.search.FullTextQuery query = 
    s.createFullTextQuery( luceneQuery, Book.class );
query.setProjection( "title", "mainAuthor.name" );
query.setResultTransformer( 
    new StaticAliasToBeanResultTransformer( 
        BookView.class, 
        "title", 
        "author" ) 
);
List<BookView> results = (List<BookView>) query.list();
for(BookView view : results) {
    log.info( "Book: " + view.getTitle() + ", " + view.getAuthor() );
}

However, the StaticAliasToBeanResultTransformer class does not exist in the Hibernate core jar.

Does anyone know if this is supposed to be a different class that I have not been able to identify yet? Or does it exist in another Hibernate project that I have not included?

I need to accomplish this idea of mapping indexed fields to properties in my “BookView” bean, since my properties and fields are not named the same. I am using Hibernate 4.1.8 and Hibernate Search 4.1.1

AFAIK there are no such class in Hibernate codebase. I believe it was part of the samples one day, but nowhere to be found since.

The easiest way is to write your own implementation.
