Überprüfung für Abfrage nach Methode JPQL fehlgeschlagen

Ich implementiere eine Abfrage, die Ausgabe im benutzerdefinierten Objekt zurückgibt. Bei meiner Implementierung erhalte ich einen Fehler:

"Methode public abstract Java.util.List org.degs.repository.ConsolidateresponseRepository.transactions ()!"

JPQL-Repository-Code:

@Query(value = "SELECT new org.degs.beans.ConsolidateResDB(DATE_FORMAT(ts, '%d-%m-%Y') AS transdate,IFNULL(COUNT(orderreqid),0),IFNULL(COUNT(failamount),0),IFNULL(SUM(amount),0),IFNULL(SUM(successamount),0),IFNULL(SUM(failamount),0),IFNULL(COUNT(successcount),0)) FROM Consolidateresponse GROUP BY DATE_FORMAT(ts, '%d-%m-%Y') ORDER BY ts DESC")
public List<ConsolidateResDB> transactions();

ConsolidateResDB Bean:

public class ConsolidateResDB {
    String transdate;
    long total;
    long failcount;
    double totalamount; double successamount;
    double failamount;
    long successcount;
}

Ich habe bereits Nullwerte in der Abfrage selbst verarbeitet und eine normale Ausgabe erhalten, wenn ich dieselbe Abfrage in mysql db terminal ausführe, aber während der Implementierung in JPA und Spring Boot immer noch den Fehler NullPointerException erhalte:

Sie haben Spring angewiesen, diese Abfrage als native zu behandeln. Andernfalls wird versucht, es gemäß der JPA-Spezifikation zu validieren.

Versuchen:

@Query(value = "SELECT ...", nativeQuery = true)
public List<Object[]> transactions();

Beachten Sie, dass in diesem Fall die NEW-Operatorsyntax nicht verwendet werden kann und Sie das Ergebnis als Array von Object behandeln müssten.

Alternativ

Wenn Sie die Ergebnisse direkt einer POJO-Klasse zuordnen möchten, müssen Sie Folgendes tun (vorausgesetzt, Sie verwenden JPA 2.1+):

1) Definiere das Mapping:

@SqlResultSetMapping(
    name="transactionsMapping",
    classes={
        @ConstructorResult(
            targetClass=ConsolidateResDB.class,
            columns={
                @ColumnResult(name="transdate"),
                @ColumnResult(name="orderreqid")
                // further mappings ...
            }
        )
    }
)

2) Definieren Sie eine native Abfrage

@NamedNativeQuery(name="transactions"
    , query="SELECT DATE_FORMAT(ts, '%d-%m-%Y') AS transdate, IFNULL(COUNT(orderreqid),0) ... ")

) Definiere diese Methode im CrudRepository ohne das @Query Anmerkung:

public List<ConsolidateResDB> transactions();

Für Frühlingsdaten 2.0.5 Und höher

Nachdem ich eine Lösung von Maciej ausprobiert hatte, begann sich mein Code zu beschweren "Got different size of tuples and aliases". Um das Problem in der neuesten Version zu beheben, müssen wir hinzufügen

@Query(<Entity.FunctionName>, nativeQuery=true). 

Dies brachte meinen Code dazu, e2e zu funktionieren.

Ich hatte das gleiche Problem, das unten für mich gearbeitet hat.

@Query(value = "select NEW org.degs.beans.ConsolidateResDB(DATE_FORMAT(c.ts, '%d-%m-%Y') ,IFNULL(COUNT(c.orderreqid),0),IFNULL(COUNT(c.failamount),0),IFNULL(SUM(c.amount),0),IFNULL(SUM(c.successamount),0),IFNULL(SUM(c.failamount),0),IFNULL(COUNT(c.successcount),0)) FROM Consolidateresponse c GROUP BY DATE_FORMAT(c.ts, '%d-%m-%Y') ORDER BY c.ts DESC") 
public List<ConsolidateResDB> transactions();
