执行Apache HttpClient时出现java.lang.InterruptedException

Question

我们在访问其他Web服务时使用org.apache.http.client.HttpClient库。

HttpRequestBase requestBase = <set uri>
httpClient.execute(requestBase);

有些时候，会发生以下这种异常：

*

有时候这个会出现。

    at

这种情况是间歇性的。可能是什么原因引起的？需要帮忙解决。非常感谢能够得到任何建议。

似乎是客户端中止了http请求。您的代码中是否使用了任何线程池执行器，提交了请求，但后来因为某些原因（可能是第三方响应缓慢）被取消了？
