以任意順序搜索用戶的名字和/或姓氏

Question

我想按任何順序通過名字，姓氏或兩者在我的用戶實體中搜索用戶。 例如： 在數據庫中我有這個用戶名：'jack'和姓''franck' ，我想輸入'ck'或'jack franck'或'franck jack'並返回此用戶。

在JPQL（春季數據），我執行此查詢，但我沒有任何結果......

@Query("select u from User u where " + 
    "((CONCAT(u.firstName, ' ', u.lastName) like CONCAT('%', :user, '%') or :user is null) " + 
    "or (CONCAT(u.lastName, ' ', u.firstName) like CONCAT('%', :user, '%') or :user is null) " + 
    "or (u.firstName like CONCAT('%', :user, '%') or :user is null) " + 
    "or (u.lastName like CONCAT('%', :user, '%') or :user is null)) ") 

編輯：

其實，我有一個需求的實體。在該實體，我有兩個用戶，參考等

整個請求是：

@Query("select d from Demande d where " + 
    "(d.reference like :reference or :reference is null) " + 
    "and (d.dateSouhaitee = :dateSouhaitee or :dateSouhaitee is null) " + 
    "and (d.datePricing = :datePricing or :datePricing is null) " + 
    "and (CONCAT(d.pricer.firstName, ' ', d.pricer.lastName) like :pricer or :pricer is null) " + 
    "and (CONCAT(d.commercial.firstName, ' ', d.commercial.lastName) like :commercial or :commercial is null) " + 
    "and (d.etat like :etat or :etat is null) " + 
    "and (d.client.raisonSociale like :clientRS or :clientRS is null) " 
) 

「定價者」和「商業」是用戶。

我的方法調用：

List<Demande> demandes = demandeRepository.search("%".concat("ref1").concat("%"), dateSouhaitee, datePricing, "%".concat("pricer1").concat("%"), null, null, "%".concat("du nord").concat("%")); 

和生成的SQL是：

select 
demande0_.id as id1_3_, 
demande0_.client_id as client_i9_3_, 
demande0_.commentaire_commercial as commenta2_3_, 
demande0_.commentaire_pricer as commenta3_3_, 
demande0_.commercial_id as commerc10_3_, 
demande0_.contrat_id as contrat11_3_, 
demande0_.date_pricing as date_pri4_3_, 
demande0_.date_souhaitee as date_sou5_3_, 
demande0_.etat as etat6_3_, 
demande0_.pricer_id as pricer_12_3_, 
demande0_.reference as referenc7_3_, 
demande0_.sites as sites8_3_ 
from 
demande demande0_ cross 
join jhi_user user1_ cross 
join jhi_user user3_ cross 
join client client5_ 
where 
demande0_.pricer_id = user1_.id 
and demande0_.commercial_id = user3_.id 
and demande0_.client_id = client5_.id 
and (
demande0_.reference like ? 
or ? is null 
) 
and (
demande0_.date_souhaitee = ? 
or ? is null 
) 
and (
demande0_.date_pricing = ? 
or ? is null 
) 
and (
(
user1_.first_name || ' ' || user1_.last_name 
) like ? 
or ? is null 
) 
and (
(
user3_.first_name || ' ' || user3_.last_name 
) like ? 
or ? is null 
) 
and (
demande0_.etat like ? 
or ? is null 
) 
and (
client5_.raison_sociale like ? 
or ? is null 
) 

感謝:-)

最後我使用的標準API。

@PersistenceContext 
private EntityManager em; 

@Override 
public List<Demande> search(String reference, ZonedDateTime dateSouhaitee, ZonedDateTime datePricing, String pricer, String commercial, EnumEtatDemande etat, String clientRS) { 
    CriteriaBuilder builder = em.getCriteriaBuilder(); 
    CriteriaQuery<Demande> query = builder.createQuery(Demande.class); 
    Root<Demande> root = query.from(Demande.class); 
    EntityType<Demande> model = root.getModel(); 

    List<Predicate> predicates = new ArrayList<>(); 
    if(reference != null){ 
     predicates.add(builder.equal(root.get(model.getSingularAttribute("reference")), reference)); 
    } 
    if(dateSouhaitee != null){ 
     predicates.add(builder.equal(root.get(model.getSingularAttribute("dateSouhaitee")), dateSouhaitee)); 
    } 
    if(datePricing != null){ 
     predicates.add(builder.equal(root.get(model.getSingularAttribute("datePricing")), datePricing)); 
    } 
    if(pricer != null){ 
     Expression<String> pricerExpression = builder.concat(
      builder.concat(root.<String>get("pricer.firstName"), " "), root.<String>get("pricer.lastName")); 
     predicates.add(builder.like(pricerExpression, pricer)); 
    } 
    if(commercial != null){ 
     Expression<String> commercialExpression = builder.concat(
      builder.concat(root.<String>get("commercial.firstName"), " "), root.<String>get("commercial.lastName")); 
     predicates.add(builder.like(commercialExpression, pricer)); 
    } 
    if(etat != null){ 
     predicates.add(builder.equal(root.get(model.getSingularAttribute("etat")), etat)); 
    } 
    if(clientRS != null){ 
     predicates.add(builder.equal(root.get(model.getSingularAttribute("client.raisonSociale")), clientRS)); 
    } 
    query.select(root).where(predicates.toArray(new Predicate[predicates.size()])); 
    return em.createQuery(query).getResultList(); 
}
