使用sun httpserver部署heroku java web服务器

我用Java sun httpserver库在我的计算机上构建了一个小型演示服务器

现在，我想公开并将其部署到heroku

简单地说，这是我的Main.java类（如下）

它是作为一个Maven项目构建的

我将herkou与我的maven项目（代码位于github上）连接起来，maven的编译和运行阶段让我获得了“构建成功”

但是，当我在本地环境（）中尝试访问我的服务器时，当我输入这个url（我的herkou站点）时，我现在收到一条消息：“页面无法加载”

herkou是否在maven项目中自动运行我的main方法（我需要这样做，因为我的服务器从我的main方法启动）

如果是这样，还有什么问题

谢谢

public class Main {
    static MySQLQueryExecutor mySQLQueryExecutor=MySQLQueryExecutor.getInstance();
    public static void main(String[] args) throws Exception {
        HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0);
        server.createContext("/test", new MyHandler());

        server.setExecutor(null);
        server.start();
        System.out.println(server.getAddress());
    }



    static class MyHandler implements HttpHandler {

        public void handle(HttpExchange t) throws IOException {
            String response = "This is Get response";
            t.sendResponseHeaders(200, response.length());
            OutputStream os = t.getResponseBody();
            os.write(response.getBytes());
            os.close();
        }
    }


}

您需要在仪表板的“资源”选项卡中将应用程序扩展到至少一个dyno

部署后运行heroku logs-t，并在此处发布输出。另外，您的

Procfile

包含哪些内容？添加到原始msgalso中，因此我没有Procfile，也没有dynoI。我使用的不是CLI，而是仪表板。如何创建procfile+dyno？它是强制性的吗？
