@SqlResultSetMapping @ConstructorResult @ColumnResult nicht für java.time.LocalDate funktioniert

Question

Ich habe eine einfache Einheit

@Entity 
@NamedNativeQueries({ 
    @NamedNativeQuery(name = "Account.dailyRegistered", 
     query = "select date(date_trunc('day', creation_date)) as period, count(1) as metric" 
      + " from account " 
      + "group by period " 
      + "order by period", 
     resultSetMapping = "PeriodMetric.byDay") 
}) 
@SqlResultSetMappings({ 
    @SqlResultSetMapping(
     name = "PeriodMetric.byDay", 
     classes = { 
      @ConstructorResult(
       targetClass = PeriodMetric.class, 
       columns = { 
        @ColumnResult(name = "period", type = java.time.LocalDate.class), 
        @ColumnResult(name = "metric", type = Integer.class) 
       } 
      ) 
     } 
    ) 
}) 
public class Account {...} 



public class PeriodMetric { 
    private LocalDate period; 
    private Integer metric; 

    public PeriodMetric(LocalDate period, Integer metric) { 
     ... 
    } 
    ... 
} 

public interface AccountRepository extends JpaRepository<Account, Long> { 
    @Query(name = "Account.dailyRegistered", nativeQuery = true) 
    List<PeriodMetric> findDailyRegistered(); 
} 

Wie man sehen kann ich für POJO als Ergebnis verwenden möchten durch native benannte Abfrage und es zu verwenden, im Frühjahr Daten JPA-Repository. Wenn ich die Repository Methode, die ich die folgende Ausnahme erhalten rufen:

Ich verbringe den ganzen Tag mit der Konfiguration nichts spielen hilft. Irgendwelche Ideen was ich falsch mache?

BTW,

Es sollte wie dieses http://www.thoughts-on-java.org/result-set-mapping-constructor-result-mappings/ basiert auf einem Artikel einfach sein.

Ich verwende Spring Data JPA 1.9.5.RELEASE, Hibernate 5.1.0.Final, Hibernate-Jpa-api 2.1.

Jsr310JpaConverters wird zu @EntityScan hinzugefügt.

Nach dem Debuggen Ich habe bemerkt, dass Hibernate in meinem Fall verwendet org.hibernate.type.SerializableType mit Bezug auf java.time.LocalDate und konnte nicht Ergebnis Wert LOCALDATE deserialisieren, sondern auch für andere Fälle verwendet Hibernate org.hibernate.type.DateType mit Bezug auf java.time.LocalDate und es funktioniert für diese Fälle (zB nicht benannte native Abfragen).

Answer 1

Verwenden Hibernate Typ Java LOCALDATE entspricht, wie unten:

@ColumnResult(name = "period", type = LocalDateType.class),
