Some properties are generated at insert or update time by your database. Hibernate can deal with such properties and triggers a subsequent select to read these properties.

@Entity
public class Antenna {
    @Id public Integer id;
    @Generated(GenerationTime.ALWAYS) @Column(insertable = false, updatable = false)
    public String longitude;

    @Generated(GenerationTime.INSERT) @Column(insertable = false)
    public String latitude;
}

Annotate your property as @Generated You have to make sure your insertability or updatability does not conflict with the generation strategy you have chosen. When GenerationTime.INSERT is chosen, the property must not contains insertable columns, when GenerationTime.ALWAYS is chosen, the property must not contains insertable nor updatable columns.

@Version properties cannot be @Generated(INSERT) by design, it has to be either NEVER or ALWAYS.
