Mehrere resouceBean Konfiguration in CXF mit Spring

Also verbringe ich einige Zeit mit der Suche im internet, fand aber keine Lösung für dieses problem. Es ist ein Hinweis in der SCHRIFTLICHEN Dokumentation, die verwendet werden können, um daraus die Lösung.

http://cxf.apache.org/docs/jax-rs-basics.html#JAX-RSBasics-Customselectionbetweenmultipleresources

Daher schrieb ich eine benutzerdefinierte Ressource-Komparator, haben die entsprechenden jaxrs:server-Konfiguration und-Eureka! es funktionierte!. Nun, ich habe 2 Implementierung Klassen zugeordnet, um eine einzelne Ressource/Adresse in javax:rs-Adresse.

Bitte beachten Sie, dass Logik in benutzerdefinierten Ressource Komparator unten gezeigt variieren, basierend auf der URL-Muster.

Ich würde lösen das problem auf diese Weise:

• Entfernen "Benutzerdefinierte Ressource-Komparator" (es gibt keine Notwendigkeit zu)

• Entfernen diese:

  <dependency>
      <groupId>org.apache.cxf</groupId>
      <artifactId>cxf-bundle-jaxrs</artifactId>
      <version>2.5.0</version>
  </dependency> 

• In der account-servlet.xml/Datei ApplicationContext:

  <beans>
      <jaxrs:server id="accountService" address="/rest">
          <jaxrs:serviceBeans>
              <ref bean="accountServiceImpl" />
              <ref bean="transferServiceImpl" />
          </jaxrs:serviceBeans>
      </jaxrs:server>
  </beans>

• In der Bohnen/Klasse Umsetzung:

  ...
  @Context("accountServiceImpl")
  @Path("/account")
  public class Accountservice{
  ...

Und das ist alles. 🙂
