Question

我正在使用Apache Tomcat上托管的Java Alexa Skills Kit SDK实现Alexa Skills逻辑（speechlets）。但是，我需要将项目移动到基于Apache Sling的服务器。它基于OSGi容器（Apache Felix）。我发现Sling DI机制非常有用。然而，看起来Java Alexa Skills Kit SDK完全没有为此类用途做好准备。主要问题是SDK servlet是一个普通的Java servlet，而Sling不支持它。此外，SDK甚至不是OSGi包。在Sling风格中使用它会很好，但我不想从头开始复制SDK。

有没有人在OSGi容器中创建Skills作为Sling服务？我必须自己创建一个SlingServlet吗？ Java Alexa Skills Kit SDK可以与Sling服务一起使用吗？

Answer 1

你是对的，Java Alexa Skills Kit SDK不支持OSGi，servlet也不能与Sling一起使用。但是，API的其余部分（除了servlet之外）由普通的Java对象组成，因此可以将它与Sling一起使用。这就是我创建alexa-skills-sling库的原因，它将Java Alexa Skills Kit SDK包装成Sling功能，以便您可以使用服务和DI机制。

要使用它，您需要添加依赖项：

<dependency>
  <groupId>eu.zacheusz.sling.alexa</groupId>
  <artifactId>alexa-skills-sling</artifactId>
  <version>1.2.1</version>
</dependency>

并将其安装为OSGi包。例如：

<plugins>
   <plugin>
      <groupId>org.apache.sling</groupId>
      <artifactId>maven-sling-plugin</artifactId>
      <executions>
         <execution>
            <id>install-dependency</id>
            <goals>
               <goal>install-file</goal>
            </goals>
            <phase>install</phase>
            <configuration>
               <!-- install dependency to test AEM Server -->
               <slingUrl>http://${vm.host}:${vm.port}/apps/alexa/install</slingUrl>
               <deploymentMethod>WebDAV</deploymentMethod>
               <user>${vm.username}</user>
               <password>${vm.password}</password>
               <groupId>eu.zacheusz.sling.alexa</groupId>
               <artifactId>alexa-skills-sling</artifactId>
               <version>${alexa-skills-sling.version}</version>
               <packaging>jar</packaging>
            </configuration>
         </execution>
      </executions>
   </plugin>
</plugins>

然后，为了实现单个意图逻辑，只需将吊索注释添加到实现中，它就会被库拾取。

@Component
@Service(IntentHandler.class)

Here is a very basic example的Intent逻辑实现和you can find more examples in this project：

@Component
@Service(IntentHandler.class)
public class ExampleSimpleIntentHandlerService implements IntentHandler {

    private static final String SLOT_NAME = "mySlot";
    private static final String INTENT_NAME = "myIntent";

    @Override
    public boolean supportsIntent(String intentName) {
        return INTENT_NAME.equals(intentName);
    }

    @Override
    public SpeechletResponse handleIntent(final SpeechletRequestEnvelope<IntentRequest> requestEnvelope) {

        final IntentRequest request = requestEnvelope.getRequest();
        final Intent intent = request.getIntent();
        final Slot slot = intent.getSlot(SLOT_NAME);

        final String responseMessage;
        if (slot == null) {
            responseMessage = format(
                    "I got your request, but there is no slot %",
                    SLOT_NAME);
        } else {
            responseMessage = format(
                    "I got your request. Slot value is %s. Thanks!",
                    slot.getValue());
        }
        return newTellResponse(responseMessage);
    }

    private SpeechletResponse newTellResponse(final String text) {
        return SpeechletResponse.newTellResponse(newPlainTextOutputSpeech(text));
    }

    private PlainTextOutputSpeech newPlainTextOutputSpeech(final String text) {
        final PlainTextOutputSpeech speech = new PlainTextOutputSpeech();
        speech.setText(text);
        return speech;
    }
}
