经过网上查找，说是缺少相关jar包httpcore、httpclient；或者是jar包版本冲突。
结合自身项目配置，项目中已经配置了httpclient的4.5.1版本，但是没配置httpcore。
于是将httpclient升到最高版本4.5.12，添加httpcore。
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<version>4.4.13</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.12</version>
</dependency>
然后maven打包，重启项目，发送请求，结果成功。
顺便提一下，如果存在父级服务则在父级添加依赖申明版本（如上述代码），子服务依赖时不需申明版本（如下代码）。
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
</dependency>
注：本文是日常异常解决记录，仅供参考，谢谢浏览。
httpclient版本冲突,maven工程中传递依赖导致的版本冲突
