I've been searching for a while and I don't find what i want...
Here is my code :
public List<MasseSalariale> findMasseSalarialeByCriteria(List<Section> sections,
Integer exercice, List<BpCaEtats> etats) {
List<String> etatString = new ArrayList<String>();
for (BpCaEtats e : etats) {
etatString.add(BpCaEtats.bpCaEtatToString(e));
}
CriteriaBuilder builder = this.getCriteriaBuilder();
CriteriaQuery<MasseSalariale> query = builder.createQuery(MasseSalariale.class);
Root<MasseSalariale> masseSalariale = query.from(MasseSalariale.class);
Join<MasseSalariale, Etablissement> etablissement =
masseSalariale.join(MasseSalariale_.etablissement);
Predicate p1 = builder.equal(masseSalariale.get(MasseSalariale_.annee), exercice);
Expression<List<Section>> exp2 = etablissement.get(Etablissement_.sections);
Predicate p2 = exp2.in(sections);
Expression<String> exp3 = masseSalariale.get(MasseSalariale_.etat);
Predicate p3 = exp3.in(etatString);
query.select(masseSalariale).where(builder.and(p1, p2, p3));
return this.find(query);
}
Basically, I need to know if one (at least) value in the section list from etablissement is contained in the section list in parameter. But the predicate p2 is wrong I think...
Using ListJoin, it worked well :
Thanks
