PUSHY APNS - AnnotatedSocketException：网络无法访问：api.sandbox.push.apple.com/2620

Question

我使用PUSHY库0.15.2版本通过Spring boot向ios设备发送推送通知。

APNS 代码如下 -

ApnsClientBuilder clientBuilder = new ApnsClientBuilder();
            clientBuilder.setApnsServer(ApnsClientBuilder.DEVELOPMENT_APNS_HOST);
            clientBuilder.setConnectionTimeout(Duration.ofMillis(60000));
            File file = new File(getClass().getClassLoader().getResource("zzzzz").getFile());
            clientBuilder.setClientCredentials(file, "yyyyy");

            apnsClient = clientBuilder.build();

            ApnsPayloadBuilder payloadBuilder = new SimpleApnsPayloadBuilder();
            payloadBuilder.setAlertTitle("xxxx");
            payloadBuilder.setAlertBody("This is test message");

            SimpleApnsPushNotification pushNotification = new SimpleApnsPushNotification(messageDto.getDeviceId(),
                    "com.np.gotprint", payloadBuilder.build());
            apnsClient.sendNotification(pushNotification).get();
            
            System.out.println("send successfully");

但我收到以下错误 -

Caused by: io.netty.channel.AbstractChannel$AnnotatedSocketException: Network is unreachable: api.sandbox.push.apple.com/2620:149:208:304:0:0:0:1f:443

    at io.netty.util.internal.SocketUtils.connect(SocketUtils.java:80)

注意 - 当我在本地运行代码时，它工作正常，当我在临时环境中部署时抛出错误。

我在这里做错了什么吗？

基于您得到的异常

“网络无法访问：api.sandbox.push.apple.com/2620:149:208:304:0:0:0:1f:443”,

您似乎正在尝试使用 IPv6，但您的网络不支持它。 您可以使用以下系统属性强制 IPv4 首选项。

-Djava.net.preferIPv4Stack=true.
