Kannel SMS 发送回执 URL 如何在 Java 中使用

问：

我是 kannel 的新手，我可以通过调用 kannel sendSms get url 成功发送短信。我想获得交货报告，建议使用回调 dlr-ulr，我已包含在 url 中。但是无法决定我需要开发Spring Boot应用程序还是servlet应用程序。最后，我将如何从回调 url 中提取值。

`CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpGet httpGet = null;
        CloseableHttpResponse response = null;
        HttpEntity entity = null;

        try {
            String callbacjUrl="http://localhost:8080/hello?&smc_id=%F&dlr=%d";
            // Create GET URL
            URI uri = new URIBuilder().setScheme("http").setHost("10.0.0.190:15015").setPath("/cgi-bin/sendsms")
                //  URI uri = new URIBuilder().setScheme("http").setHost("localhost:15001").setPath("/cgi-bin/sendsms")
                //  URI uri = new URIBuilder().setScheme("http").setHost("localhost:15015").setPath("/cgi-bin/sendsms")
                    .setParameter("username", "user") // kannel username

                    .setParameter("to", "658123657") // destination (must be a mobile number)

            httpGet.setHeader("content-type", "text/plain");
            System.out.println("hello before excute");
            response = httpclient.execute(httpGet);
            
            System.out.println("hello after excute"+response.getParams().toString());

            // LOG.info(response.getStatusLine());
            entity = response.getEntity();
    
        URL url = new URL(callbacjUrl);
            url.getQuery();
            System.out.println(getQueryMap(url.getQuery()));
             String result = new BufferedReader(new InputStreamReader(entity.getContent()))
                       .lines().collect(Collectors.joining("\n"));
             System.out.println("result --"+result);
            System.out.println("entity.getContent()"+entity.getContent().toString());

            EntityUtils.consume(entity);
            System.out.println("EntityUtils.consume() ended");

        } catch (Exception e) {

             System.out.println("e"+e.getMessage());
            e.printStackTrace();
        } finally {
            try {
                response.close();
            } catch (IOException e) {

                e.printStackTrace();
            }
        }`
