java - How can I run a secondary / augmented query in Spring Data JPA to determine calculated value? -
i using spring data 1.4.1 eclipselink 1.5.0.
i have entity such:
@entity public class { // ... other fields ... @transient private boolean calculatedfield; }
i ideally want populate calculated field on post load. value logically rather complicated query. in hibernate, can annotate field @formula. aware eclipselink not provide similar functionality. bound eclipselink.
i wondering if spring data jpa provides mechanisms processing entity information create , run "additional" queries, if will. or augment original query?
my first thought implement repository , set field in secondary query. i'd rather avoid concrete implementations of repository if could.
suggestions?
i ended implementing descriptorcustomizer. prefer orm agnostic solution. time being, solved issue.
