我试图让基于OSGI的应用程序通过Google平台Java与pub/sub进行通信。不过，我不能让它打电话。它在文章底部的堆栈跟踪中出错。我尝试将它要求的依赖项添加到同一个包中，但没有运气。下面是我用来尝试调用的代码。

        GoogleCredentials googleCredentials = GoogleCredentials.fromStream(AbTestGoogleCloudUpdaterJobHandler.class.getResourceAsStream("/GoogleCloudPlatformKey.json"));
        Publisher publisher = Publisher.defaultBuilder(
                TopicName.create("foobar-172318", "dev-foo"))
                .setCredentialsProvider(FixedCredentialsProvider.create(googleCredentials))
                .build();
        PubsubMessage pubsubMessage =
                PubsubMessage.newBuilder().setData(ByteString.copyFromUtf8("WOOT!")).build();
        publisher.publish(pubsubMessage);

我遇到了同样的问题，并能够解决这个问题。我知道这个答案不会对原来的海报有所帮助。但张贴以供日后参考。这里的主要问题是gRPC使用SPI并依赖于ServiceLoader在运行时加载适当的impl。要想克服这一问题，我们必须

  1. 将以下依赖项转换为元-INF中保存SPI资源的包 grpc-核心 grpc-netty netty-tcnative-boringssl-static
  2. 将(私有包)依赖项打包到我们的包中，并复制SPI资源以输出META。

我选择第二种选择。在这里，我们也可以遵循两种方法。

  1. 使用带包插件的maven依赖插件来解压缩和复制资源，正如解释的这里。
  2. 手动将SPI资源复制到我们的项目资源目录中。

目前，我使用的选项2及以下是最终资源目录。

在决定时，请参考这。希望这能帮上忙！
