Benannte Parameter auf Java8

Question

UPD: Schließlich funktioniert dieses feature, mit laufendem Projekt von der Befehlszeile, aber nicht von IntellijIdea. Wie kann ich Junit in Intellijidea zwingen, mit -Parameters Flagge zu arbeiten?

Ich habe eine Java-Anwendung mit Federdaten jpa und Hibernate. Ich verwende Java8 es zu laufen und das ist mein Beispiel CrudRepository:

public interface CRepository extends CrudRepository<C, Integer> { 
@Transactional(readOnly = true) 
@Query("select sum(cnt.went-cnt.left) from C cnt " + 
     "where cnt.shop = :shop " + 
     "and cnt.time between :startDate and :endDate") 
int sumBetweenDatesByShop(Shop shop, Timestamp startDate, Timestamp endDate); 
} 

Wenn ich Unit-Test renne zu überprüfen, es funktioniert, ich bin eine solche Ausnahme bekommen:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Name for parameter binding must not be null or empty! For named parameters you need to use @Param for query method parameters on Java versions < 8.; nested exception is java.lang.IllegalArgumentException: Name for parameter binding must not be null or empty! For named parameters you need to use @Param for query method parameters on Java versions < 8.

Warum bekomme ich es, wenn meine Spring-Boot-Anwendung kompiliert, verpackt und auf dem PC mit dem einzigen installierten Java = Java8 ausgeführt wird.

Vielen Dank für Ihre Zeit und Hilfe.

Wenn ich versuche Params in Abfrage wie '? 1' oder Annotation Params mit @Param() Annotation wird es gut funktionieren, aber ich würde gerne wissen, warum es nicht so funktioniert wie es jetzt ist.

Sieht aus wie die Antwort ist -parameters Flag zum Compiler hinzufügen, aber ich habe keine Ahnung, wie dieses Flag für Spring-Boot-Anwendung hinzufügen, habe ich versucht, es so hinzuzufügen, aber ich denke Maven Compiler-Plugin wird nicht verwendet im Frühjahr-Boot-Anwendung überhaupt kompilieren (wahrscheinlich wegen IntelliJ IDEA?):

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <configuration> 
      <compilerArgs> 
        <arg>-parameters</arg> 
      </compilerArgs> 
    </configuration> 
</plugin> 

Answer 1

Unter der Annahme, dass Sie die folgende Konfiguration in Ihrem pom haben:

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <configuration> 
      <compilerArgs> 
        <arg>-parameters</arg> 
      </compilerArgs> 
    </configuration> 
</plugin> 

in Intellij, gehen/Debug-Konfigurationen zu starten , finden Sie die Konfiguration, mit der Sie den Komponententest ausführen (Oder erstellen Sie eine neue für das Projekt/Klasse Sie betroffen sein) wollen und am botton gibt es eine „Vor dem Start eines“ Abschnitt, der in ihm ein Element hat:

• Machen

das Element entfernen indem Sie es auswählen und auf die Schaltfläche - klicken. Dann fügen Sie mit der + Schaltfläche einen neuen "Run Maven Goal" Gegenstand hinzu. Wählen Sie im Dialogfeld "Hinzufügen" das entsprechende Verzeichnis aus, in dem sich Ihr Pom befindet. Und in der Befehlszeile Typ "test-compile". Führen Sie einen "mvn clean" von Intellij oder der Befehlszeile aus. Fertig.
