OpenDaylight 控制器应用程序缺少依赖项 (Sodium SR1)答案

【问题描述】：

我正在按照这里的说明编写一个简单的 hello world RPC：https://docs.opendaylight.org/en/stable-sodium/developer-guide/developing-apps-on-the-opendaylight-controller.html

在示例 HelloProvider 类中，构造函数是：

 public HelloProvider(final DataBroker dataBroker, final RpcProviderService rpcProviderService) {
     this.dataBroker = dataBroker;
     this.rpcProviderService = rpcProviderService;
 }

需要 RpcProviderService，因此编译失败。所以我添加到 impl/src/main/resources/OSGI-INF/blueprint/impl-blueprint.xml：

      <reference id="rpcProviderService"
         interface="org.opendaylight.mdsal.binding.api.RpcProviderService"/>
         odl:type="default" />

这导致项目编译，但在测试阶段失败：

Missing dependencies: 
(objectClass=org.opendaylight.controller.md.sal.dom.api.DOMNotificationPublishService) 
(objectClass=org.opendaylight.controller.md.sal.dom.api.DOMDataBroker) 
(objectClass=org.opendaylight.controller.md.sal.dom.spi.DOMNotificationSubscriptionListenerRegistry) 
(objectClass=org.opendaylight.controller.md.sal.dom.api.DOMMountPointService) 
(objectClass=org.opendaylight.controller.md.sal.dom.api.DOMRpcService) 
(objectClass=org.opendaylight.controller.md.sal.dom.api.DOMNotificationService) 
(objectClass=org.opendaylight.controller.md.sal.dom.api.DOMDataBroker) 
(objectClass=org.opendaylight.controller.md.sal.dom.api.DOMRpcProviderService)

org.opendaylight.controller 包已经被拉入，所以也许我还缺少其他东西。有什么建议吗？

我也面临同样的问题。我修改了 impl-blueprint.xml 如下：

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
   xmlns:odl="http://opendaylight.org/xmlns/blueprint/v1.0.0"
   odl:use-default-for-reference-types="true">

<reference id="dataBroker"
  interface="org.opendaylight.mdsal.binding.api.DataBroker"
  odl:type="default" />

<reference id="rpcProviderService"
         interface="org.opendaylight.mdsal.binding.api.RpcProviderService"
         odl:type="default" />

<bean id="provider"
  class="org.opendaylight.hello.impl.HelloProvider"
  init-method="init" destroy-method="close">
  <argument ref="dataBroker" />
  <argument ref="rpcProviderService" />
</bean>

在此之后，我在通过 HTTP 方法访问 REST API 时遇到了另一个问题。我收到错误 401 - 未经授权。为此，我安装了 odl-mdsal-apidocs 并开始工作。

<dependency>
  <groupId>org.opendaylight.netconf</groupId>
  <artifactId>odl-mdsal-apidocs</artifactId>
  <version>1.10.2</version>
  <type>xml</type>
  <classifier>features</classifier>
</dependency>
