问题描述

我需要部署到仅支持Tomcat容器并且还想将Vert.x作为异步框架运行的PaaS(HANA云平台).

I need to deploy to a PaaS (HANA Cloud Platform) that only supports a Tomcat container and also want to run Vert.x as an async framework.

到目前为止,我所做的是通过servlet引导Vert.x:

What I did so far is to bootstrap Vert.x through a servlet:

public class VertxServlet extends HttpServlet {
...
    @Override
    public void init(ServletConfig cfg) {

        Vertx vertx = Vertx.vertx();
        vertx.createHttpServer().requestHandler(new Handler<HttpServerRequest>() {
            public void handle(HttpServerRequest req) {
              System.out.println("Got request: " + req.uri());
              System.out.println("Headers are: ");
              for (Map.Entry<String, String> entry : req.headers()) {
                System.out.println(entry.getKey() + ":" + entry.getValue());
              }
              req.response().headers().set("Content-Type", "text/html; charset=UTF-8");
              req.response().end("<html><body><h1>Hello from vert.x!</h1></body></html>");
            }
          }).listen(8888);
    }
...
}

然后在我的web.xml中输入:

And in my web.xml I put this:

<servlet>
    <servlet-name>VertxServlet</servlet-name>
    <display-name>VertxServlet</display-name>
    <description></description>
    <servlet-class>com.mypackage.VertxServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

效果很好.问题是PaaS无法配置端口映射.包括反向代理在内的整个Tomcat是一个准备好的解决方案.

It works quite well. The problem is that the PaaS is not able to configure the port mapping. The whole Tomcat including the reverse proxy is a prepared solution.

问题:

  • 将Vert.x作为.war文件运行是否可行? 有什么局限性和以后可能会遇到的困难?

  • Is it a viable approach to run Vert.x as a .war file or does it have any limitations and difficulties that may occur later?

是否可以将我的小型Vert.x服务器绑定到默认的Tomcat端口,而不会发生端口冲突?

Is there a way of binding my little Vert.x server to the default Tomcat port without running into a port conflict?

谢谢

推荐答案

我找到了解决方案.有一个HTTP代理Servlet,您可以在其中轻松地将HTTP请求转发到Vert.x套接字: https://github.com/mitre/HTTP-Proxy-Servlet 对于HTTP来说效果很好.

I have found a solution. There's a HTTP Proxy Servlet where you can easily forward HTTP requests to the Vert.x socket: https://github.com/mitre/HTTP-Proxy-Servlet It works well for HTTP.

不幸的是,此解决方案不支持Web套接字.

But this solution does not support web sockets, unfortunately.
