JPA Metamodel generation missing attributes

Question

I'm using JPA metamodel generation http://relation.to/Bloggers/HibernateStaticMetamodelGeneratorAnnotationProcessor to be able to execute criteria queries with names of the attributes.

I'm generating the metamodel classes trough ANT and hibernate-jpamodelgen-4.3.5.Final http://mvnrepository.com/artifact/org.hibernate/hibernate-jpamodelgen/4.3.5.Final

THE PROBLEM IS: If i have an entity like this:

@Entity public class Order 
{
    @Id 
    Integer id;
    @ManyToOne 
    Customer customer;
    @OneToMany 
    Set<Item> items;
    BigDecimal totalCost;
    java.net.URI uri;
    ...
}

with setters and everything...

The metamodel generated will be like this:

@StaticMetamodel(Order.class)
public class Order_ {
    public static volatile SingularAttribute<Order, Integer> id;
    public static volatile SingularAttribute<Order, Customer> customer;
    public static volatile SetAttribute<Order, Item> items;
    public static volatile SingularAttribute<Order, BigDecimal> totalCost;
}

So the URI is missing in the generated class.

Maybe it's because of the missing standard no attribute constructor for the java.net.URI?

THANKS!

Answer 1

Use the @Basic annotation to annotate the field. You may have to provide an attribute converter.

Answer 2

Please have a look at this thread. You should map String to / from java.net.URI in getter / setter methods.
