JPA Criteria ParameterExpression - QueryException Named parameter [ard] not set - jpa

Question

I try executing a dynamic query using ParameterExpression but get an exception.
my method:
public List<Atividade> buscarAtividades(Armario armario) {
CriteriaBuilder builder = manager.getCriteriaBuilder();
CriteriaQuery<Atividade> criteriaQuery = builder.createQuery(Atividade.class);
Root<Atividade> atividade = criteriaQuery.from(Atividade.class);
criteriaQuery.select(atividade);
criteriaQuery.distinct(true);
List<Predicate> predicates = new ArrayList<Predicate>();
if(armario != null){
ParameterExpression<Armario> ard = builder.parameter(Armario.class, "ard");
predicates.add(builder.equal(atividade.get("armario").get("numero"), ard));
}
criteriaQuery.where(predicates.toArray(new Predicate[0]));
TypedQuery<Atividade> query = manager.createQuery(criteriaQuery);
return query.getResultList();
}
When my query is executed I receive stack:

Answer 1

When you define a parameter in a Criteria query (builder.parameter(Armario.class, "ard") which creates a parameter with name ard) you then need to set the value of the parameter to use when running it.
In your case this means
query.setParameter("ard", someValue);
before calling query.getResultList().

Answer 2

you can use ParameterExpression like this:
assume that you have some input filter, an example could be this:
in your query you have to check the value of a fiscal Code.
1) inizialize a predicateList(use for where clause) and a paramList(use for param)
Map<ParameterExpression,String> paramList = new HashMap();
List<Predicate> predicateList = new ArrayList<>();
2 )check if the input is null and create predicateList and param
if( input.getFilterCF() != null){
//create ParameterExpression
ParameterExpression<String> cf = cb.parameter(String.class);
//if like clause
predicateList.add(cb.like(root.<String>get("cf"), cf));
paramList.put(cf , input.getFilterCF() + "%");
//if equals clause
//predicateList.add(cb.equal(root.get("cf"), cf));
//paramList.put(cf,input.getFilterCF()());
}
3) create the where clause
cq.where(cb.and(predicateList.toArray(new Predicate[predicateList.size()])));
TypedQuery<Tuple> q = _em.createQuery(cq);
4) set param value
for(Map.Entry<ParameterExpression,String> entry : paramList.entrySet())
{
q.setParameter(entry.getKey(), entry.getValue());
}

Answer 3

You have to join the associated entity to access its fields for operation like adding filter or cascading the joins. Also if you are adding a parameter to query, set the parameter before executing it.
CriteriaBuilder builder = manager.getCriteriaBuilder();
CriteriaQuery<Atividade> criteriaQuery = builder.createQuery(c.class);
Root<Atividade> atividade = criteriaQuery.from(Atividade.class);
criteriaQuery.select(atividade);
criteriaQuery.distinct(true);
Join<Atividade, Armario> armarioJoin = atividade.join("armario", JoinType.INNER)
List<Predicate> predicates = new ArrayList<Predicate>();
if(armario != null){
ParameterExpression<Armario> ard = builder.parameter(String.class, "ard");
predicates.add(builder.equal(armarioJoin.get("numero"), ard));
}
criteriaQuery.where(predicates.toArray(new Predicate[0]));
TypedQuery<Atividade> query = manager.createQuery(criteriaQuery);
query.setParameter("ard", armario.getNumero());
return query.getResultList()
