Wie kann ich mit Wildfly auf meine REST-Ressource zugreifen?

Question

Hallo Ich entwickle eine Rest API mit IntelliJ folgende the official doc.

Aber ich bekomme eine 404 nicht gefunden Fehler beim Zugriff auf die Ressource ... Ich kann weiterhin auf die index.jsp Seite zugreifen. Ich habe jeden Schritt von De Doc verfolgt, aber ich benutze Wildfly anstelle von Glassfish. Hier

ist die Ressource:

@Path("devices") 
public class DevicesResource { 

    @GET 
    @Produces(MediaType.TEXT_PLAIN) 
    public String getAllDevices() { 
     return "Hello world from thingsplay."; 
    } 

} 

Hier ist die Anwendung Kind Klasse:

@ApplicationPath("/api/v2.0") 
public class ApplicationConfig extends Application { 

    @Override 
    public Set<Class<?>> getClasses() { 
     Set<Class<?>> resources = new HashSet<>(); 
     addResourceClasses(resources); 
     return resources; 
    } 

    public void addResourceClasses(Set<Class<?>> resources) { 
     resources.add(be.thingsplay.resources.DevicesResource.class); 
    } 

} 

Also, wenn ich http://localhost:8080/api/v2.0 greife ich auf die Index-Seite zu bekommen, aber wenn ich versuche, http://localhost:8080/api/v2.0/devices zuzugreifen ich ein 404 Nicht gefunden Fehler.

Als ich mir das Artefakt ansah, bemerkte ich, dass die Jersey-Bibliothek nicht im Krieg enthalten war. Aber wenn ich versuche, es dem Krieg hinzuzufügen, erhalte ich Ausnahmen, wenn ich versuche, die Anwendung zu implementieren.

Die Ausnahmen erhalte ich:

Answer 1

Zu allererst Sie keine REST Implementierung Gläser (wie Jersey) hinzufügen müssen, um Ihre Anwendung, da Java EE 7 Server wie WildFly und GlassFish kommen damit kostenlos.

Das Problem besteht darin, dass in Ihren URLs der Kontextpfad Ihrer Anwendung fehlt (rest_glassfish_hello_world_war_exploded in dem von Ihnen referenzierten Lernprogramm).

dh.

http://localhost:8080/rest_glassfish_hello_world_war_exploded /api/v2.0/devices

wo rest_glassfish_hello_world_war_exploded sollten mit Ihrem tatsächlichen Anwendungsnamen ersetzt werden, wenn es anders ist: die richtige Service-URL sollte etwas ähnliches sein.
