二、原因分析
1.官网解释是
org.apache.commons.httpclient.NoHttpResponseException：In some circumstances, usually when under heavy load, the web server may be able to receive requests but unable to process them.
A lack of sufficient resources like worker threads is a good example.
This may cause the server to drop the connection to the client without giving any response.
HttpClient throws NoHttpResponseException when it encounters such a condition.
In most cases it is safe to retry a method that failed with NoHttpResponseException.
在某些情况下，通常是在高负载下，web服务器可能能够接收请求，但无法处理它们。缺乏足够的资源(比如工作线程)就是一个很好的例子。这可能导致服务器在不给出任何响应的情况下断开到客户机的连接。HttpClient在遇到这种情况时抛出NoHttpResponseException。在大多数情况下，重试使用NoHttpResponseException失败的方法是安全的。
官网给出的解决办法就是：重试调用失败的方法
2.自我验证及复现该问题到底什么情况下会发生（待定）
