HttpURLConnection在Springboot中封装的工具类

本文主要是介绍HttpURLConnection在Springboot中封装的工具类，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

AnroidSDK本身自带两种网络框架HttpClient和HttpURLConnection，但Google在API23之后放弃了HttpClient的支持推荐使用HttpURLConnection。

1. POM依赖项

<dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><scope>compile</scope>
</dependency>

2. 封装工具类
