java – Apache Http Client打印“[读取] I / O错误：读取超时”“

我正在使用apache http客户端v4.5并将其用作REST客户端.在某些情况下,我识别出一个错误“[读取] I / O错误：读取超时”,它来自httpclient框架,当它读取接收到的内容并将其显示为最后一条消息时.

它似乎没有影响,但我想知道是否有人知道它来自何处以及如何解决它.根据以下主题(link),似乎是“mutlithreaded”配置的问题.

但是我只使用http客户端的默认配置,当我使用版本v4时,我不知道如何将“multithreaded”设置为false以查看它是否有任何区别.

我也尝试设置超时但它没有帮助.

任何提示？

我的Http客户端初始化

HttpClientBuilder httpBuilder = HttpClientBuilder.create();

//      set timeout did not helped
//      RequestConfig.Builder requestBuilder = RequestConfig.custom();
//      requestBuilder = requestBuilder.setConnectTimeout(timeout);
//      requestBuilder = requestBuilder.setConnectionRequestTimeout(timeout);
//      requestBuilder = requestBuilder.setSocketTimeout(timeout);
//      httpBuilder.setDefaultRequestConfig(requestBuilder.build());

HttpClient httpClient = httpBuilder.build();

解决方法

我正在使用httpclient 4.5.2,在我的情况下,根据请求设置超时有助于：

HttpPost postRequest = new HttpPost("https://...");
postRequest.setHeader(...,...);

RequestConfig requestConfig = RequestConfig.custom()
                        .setSocketTimeout(1000)
                        .setConnectTimeout(1000)
                        .build();

postRequest.setConfig(requestConfig);
