JPA Criteria API-Funktion mit Doppel Parametern

Ich bin mit diesem Problem steckt und nach 2 Tagen durch die Web-Suchen Sie sind meine letzte Hoffnung: pJPA Criteria API-Funktion mit Doppel Parametern

Ich bin mit JPA Kriterien api meine Abfrage zu erstellen. Alles funktioniert gut, außer wenn ich dem Mix etwas SQL-Funktion hinzufügen möchte.

Dies ist, was ich tun, SQL-Funktion zu verwenden: Expression makePoint = criteriaBuilder.function("ST_MakePoint", Geometry.class, criteriaBuilder.parameter(double.class, "lat"), criteriaBuilder.parameter(double.class, "lng")); Expression distanceSphere = criteriaBuilder.function("ST_Distance_Sphere", double.class, place.get("coordinates"), makePoint); expression = criteriaBuilder.and(expression, criteriaBuilder.lessThanOrEqualTo(distanceSphere, radius)); criteriaQuery.select(root).where(expression);

die Erklärung funktioniert gut, aber wenn ich die Parameter einstellen: session.createQuery(criteriaQuery).setParameter("lat",lat)

Ich habe diesen Fehler:

java.lang.IllegalArgumentException: Named parameter [lat] type mismatch; expecting [double] but found [Double]

Ich versuche sogar, den Parameter mit zu setzen: double lat = 12.56; double lat = Double.parseDouble("12.552");

nichts funktioniert :(

Eigentlich im Spiel es Autoboxing hier, können Sie die Art von double.class zu Double.class in criteriaBuilder ändern. parameter() -Methode. –

den Typ von

criteriaBuilder.parameter (double.class "lat") Ändern,

criteriaBuilder .Parameter (Double.class, "Lat"),

sollte für Sie arbeiten. Für weitere Informationen refer. Führen Sie das folgende Beispiel außerdem aus, um die Ausnahme zu verstehen, die Sie anzeigen.

import java.util.ArrayList; 
import java.util.List; 

    public class Main { 

     public static void main(String args[]) { 
     List<Double> list = new ArrayList<>(); 
     double var = 1022.222; 
     list.add(var); 
     // Notice that the double is autoboxed to Double type. 
     System.out.println(list.get(0).getClass()); 
     System.out.println(double.class); 
     // System.out.println(list.get(0).getClass().equals(double.class)); 
     } 
    }

Ich versuche es bereits, wenn ich Double, die Funktion ist nicht in meiner Datenbank erkennen, und in SQL können Sie nur "doppelte Genauigkeit". – Arnaud

Können Sie versuchen, die setDouble-Methode im ursprünglichen Code-Snippet zu verwenden, das in Ihrer Frage gepostet wurde, so wird ** session.createQuery (criteriaQuery) .setParameter ("lat", lat) ** zu ** session.createQuery (criteriaQuery) .setDouble ("lat", 123.00d) **. Weitere Informationen finden Sie in den Javadocs. https://docs.jboss.org/hibernate/orm/3.5/api/org/hibernate/Query.html#setDouble(java.lang.String, double) –

Der Fehler, wenn ich von double.class zu Double.class ändern:

org.hibernate.engine.jdbc.spi.SqlExceptionHelper.logExceptions ERROR: function st_makepoint(double precision, double precision) does not exist Indice : No function matches the given name and argument types. You might need to add explicit type casts.
