java - 使用 HttpAsyncClients 设置重试次数

Question

使用典型的 HttpAsyncClients 示例:

public class AsyncClientHttpExchange {

    public static void main(final String[] args) throws Exception {
        CloseableHttpAsyncClient httpclient = HttpAsyncClients.createDefault();
        try {
            httpclient.start();
            HttpGet request = new HttpGet("http://httpbin.org/get");
            Future<HttpResponse> future = httpclient.execute(request, null);
            HttpResponse response = future.get();
            System.out.println("Response: " + response.getStatusLine());
            System.out.println("Shutting down");
        } finally {
            httpclient.close();
        }
        System.out.println("Done");
    }
}

如何设置无响应时的重试次数？我可以看到 5 个。

使用httpClientBuilder，有setRetryHandler:

httpClientBuilder.setRetryHandler(new MyRequestRetryHandler(_maxRetryCount));

HttpAsyncClients 是怎么回事？

HttpAsyncClient 4.x 不支持自动重新执行请求。此功能计划在 HttpAsyncClient 5.0 中使用
