jpush-api-java-client v3.2.17

更新日志：

PushClient 增加 setHttpClient 方法，用户可以切换 NettyHttpClient 或 NativeHttpClient 来发送请求。
代码示例：

public static void testSendPush() {
        // HttpProxy proxy = new HttpProxy("localhost", 3128);
        // Can use this https proxy: https://github.com/Exa-Networks/exaproxy
        ClientConfig clientConfig = ClientConfig.getInstance();
        JPushClient jpushClient = new JPushClient(MASTER_SECRET, APP_KEY, null, clientConfig);
        String authCode = ServiceHelper.getBasicAuthorization(APP_KEY, MASTER_SECRET);
        // Here you can use NativeHttpClient or NettyHttpClient.
        NativeHttpClient httpClient = new NativeHttpClient(authCode, null, clientConfig);
        // Call setHttpClient to set httpClient,
        // If you don't invoke this method, default httpClient will use NativeHttpClient.
        jpushClient.getPushClient().setHttpClient(httpClient);


        // For push, all you need do is to build PushPayload object.
        PushPayload payload = buildPushObject_all_alias_alert();
        try {
            PushResult result = jpushClient.sendPush(payload);
            LOG.info("Got result - " + result);
            // 如果使用 NettyHttpClient，需要手动调用 close 方法退出进程
            // If uses NettyHttpClient, call close when finished sending request, otherwise process will not exit.
            // jpushClient.close();
        } catch (APIConnectionException e) {
            LOG.error("Connection error. Should retry later. ", e);
            LOG.error("Sendno: " + payload.getSendno());

        } catch (APIRequestException e) {
            LOG.error("Error response from JPush server. Should review and fix it. ", e);
            LOG.info("HTTP Status: " + e.getStatus());
            LOG.info("Error Code: " + e.getErrorCode());
            LOG.info("Error Message: " + e.getErrorMessage());
            LOG.info("Msg ID: " + e.getMsgId());
            LOG.error("Sendno: " + payload.getSendno());
        }
    }
