Java 将asynchttpclient作为maven项目发送异步post请求并运行

我在这里完全疯了。这是我第一次使用java，它让我非常害怕

无论如何，我需要做的是创建一个小型java maven项目，在其中我监听一个特定的UDP端口（python脚本atm，模拟我应该使用的设备），然后在发送一个post请求到一个带有两个post参数的特定url之前做一些事情

我发现这个图书馆似乎得到了很好的评价和声誉

到目前为止我完成了什么

我已经成功创建了一个maven项目（显然）

编写了receiver类（工作得很好！）——该类捕获UDP消息并存储任何需要存储的内容，以便在以后发送POST消息时使用

编写了负责使用库发送POST消息的代码（我不确定它是否有效，因为我无法运行它）：

尝试通过powershell运行以下操作：

如果您能在这方面给予帮助，我们将不胜感激。乐意在需要时提供更多信息。

您还需要在类路径中包含http库。现在它只包含您的jar。您还需要将依赖项添加到cp，以便它可以找到它。maven可以为您实现这一点，但是使用java运行它时，您需要做一些明确的事情，您可以使用maven创建一个可执行的jar。你可以找到这个有用的@HenningLuther我不确定你的意思，你能给我指点方向吗？你正在配置的类路径-cp只包含你自己的工件，但不包含对http的依赖，你也必须添加它。maven将pom中定义的所有依赖项添加到类路径中，这就是它使用maven的原因。

    // To make post request to send data
  AsyncHttpClient client = Dsl.asyncHttpClient();

  BoundRequestBuilder postRequest = client
          .preparePost("http://localhost:8080/my_custom_url/")
          .addFormParam("id", myid)
          .addFormParam("stream", inData);

  // Asynchronous execution
  postRequest.execute(new AsyncHandler<Object>() {
      public State onStatusReceived(HttpResponseStatus responseStatus) throws Exception {
          System.out.print("\nstatus received");
          return null;
      }

      public State onHeadersReceived(HttpHeaders headers) throws Exception {
          System.out.print("\nheaders received");
          return null;
      }

      public State onBodyPartReceived(HttpResponseBodyPart bodyPart) throws Exception {
          System.out.print("\nbody part received");
          return null;
      }

      public void onThrowable(Throwable t) {

      }

      public Object onCompleted() throws Exception {
          System.out.print("\nexecute completed");
          return null;
      }
  });

  // Close to stop memory leaks after we are done
  try {           client.close();         } catch (IOException e) {           infoBox("Could not close AsyncHttpClient.", "Error");
      System.exit(0);         }
