JPA Criteria ParameterExpression - QueryException名前付きパラメータ[ard]が設定されていません

を使用して動的クエリを実行しようとしましたが、例外が発生します。JPA Criteria ParameterExpression - QueryException名前付きパラメータ[ard]が設定されていません

私の方法：

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(); 

}

私のクエリは、私がスタック受け取る実行された場合：

AtividadeとArmarioクラス – grizzly

追加されたクラスのコードを追加してください。実際、私は動的クエリ用のフィルタを作成したいと思いますが、Atividadeクラスの属性を作成するだけでパラメータエラーが発生します。 tnx – vila

あなたが（名前ardでパラメータを作成しbuilder.parameter(Armario.class, "ard")）基準クエリでパラメータを定義しますが、その後値を設定する必要がありますそれを実行するときに使用するパラメータの値。あなたのケースでは

これはquery.getResultList()を呼び出す前に

query.setParameter("ard", someValue);

を意味します。

tnxたくさんニール、後で試してみます。 – vila

おそらくあなたが今試したことがあるでしょう...一ヶ月後。だから、それを修正した答えを受け入れる –

申し訳ありません、あなたのヒントはcorect tnxでした。 – vila

フィルタの追加や結合のカスケードなどの操作のために、関連するエンティティに参加してそのフィールドにアクセスする必要があります。また、クエリにパラメータを追加する場合は、パラメータを実行する前に設定します。

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());

あなたは、このようParameterExpressionを使用することができます：あなたは財政コードの値をチェックする必要があなたのクエリで

：は例は、この可能性があり、あなたには、いくつかの入力フィルタを持っていることを前提としています。

1）は、句のpredicateList（使用）とparamList PARAMのための（使用）をinizialize

Map<ParameterExpression,String> paramList = new HashMap(); 
List<Predicate> predicateList = new ArrayList<>();

）入力がヌルであるかどうかをチェックし、作成predicateListと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()()); 
     }

）WHERE句

を作成

cq.where(cb.and(predicateList.toArray(new Predicate[predicateList.size()]))); 
TypedQuery<Tuple> q = _em.createQuery(cq);

）設定のparam値

 for(Map.Entry<ParameterExpression,String> entry : paramList.entrySet()) 
     { 
      q.setParameter(entry.getKey(), entry.getValue());
