我是靠谱客的博主生动小鸽子，最近开发中收集的这篇文章主要介绍TrustStrategy——Java中httpclient.jar和httpcore.jar版本差异带来的异常，觉得挺不错的，现在分享给大家，希望可以做个参考。

前言说明：当前我的工程中使用的httpclient-4.3.6.jar和httpcore-4.3.3.jar版本的包。

从上面报错提示可以看出，是org/apache/http/ssl/TrustStrategy下面找不到TrustStrategy这个类，我查了下依赖中的httpclient-4.3.6.jar和httpcore-4.3.3.jar两个包，均没有这个类。
这里写图片描述

而4.4版本中有ssl路径：
这里写图片描述
及对应org/apache/http/ssl/TrustStrategy方法。

很明显是版本不对，应该换成新版本。

很明显是版本不对，是由于httpclient-4.3.6.jar缺少NoopHostnameVerifier方法：
这里写图片描述

而4.4版本中有这个方法：

应该换成新版本，即换成httpclient-4.4.jar

查看下jar包中相应路径存在上面那个类。

最后再次执行，执行成功，无异常！

所以，下次碰到以下两个异常时：
1、

需要升级httpclient.jar和httpcore.jar两个包的版本，4.3的版本中不含有上述两个类，需要同时升级到4.4版本。

即替换为httpclient-4.4.jar和httpcore-4.4.jar
