实际上,客户端驻留在tomcat 8080中,而REST API驻留在9090中。URL移至更高环境时将有所不同。我看不到使用httpasyncclient进行的REST API调用。我从Apache网站复制了代码
https://hc.apache.org/httpcomponents-asyncclient-dev/examples.html

不确定,即使我收到异常响应也如何使通话成功

CloseableHttpAsyncClient client = HttpAsyncClients.createDefault();
    try {
        client.start();
        JsonObject obj = new JsonObject();
        obj.addProperty("username", "username");
        obj.addProperty("password", "password");



        String serverURL = "http://localhost:9090/project/api";

        HttpPost postRequest = new HttpPost(serverURL);
        StringEntity params = new StringEntity(obj.toString(), "UTF-8");
        params.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "x-www-form-urlencoded"));
        postRequest.setEntity(params);

        Future<HttpResponse> future = client.execute(postRequest, null);
        HttpResponse response = future.get();


    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    } finally {
        try {
            client.close();
        } catch (IOException e) {
            e.printStackTrace();
        }


    }


我没有找到任何有用的信息来解决此问题。任何帮助都会让我开心

javadocs说


  打开声明java.util.concurrent.ExecutionException异常
  尝试检索中止的任务的结果时抛出
  通过抛出异常。可以使用
  getCause()方法。

最佳答案

最可能的原因-httpclient版本中存在冲突。 F.e.项目依赖项包括httpclienthttpasyncclienthttpasyncclient对另一个版本的httpclient具有传递依赖。结果,项目依赖项具有2个不兼容的httpclient版本。此处将对其中一种情况进行详细说明:https://stackoverflow.com/a/49898063/4651234
