httpClient 工具类 github地址:https://github.com/yangwenjie88/http-client-utli/
现在微服务这么火,在日常开发中我们经常需要调用http接口,虽然java自身提供了net相关工具包,但是其灵活性和功能总是不如人意,
于是有了apache httpclient 类库 ,大部分时候我们都是需要用的时候,百度一下,复制黏贴就使用,也不管它什么性能优化使用连接池等等,能调通就行。
在项目中对于这个工具类库也许没有进行很好的封装。在哪里使用就写在哪里,很多地方用到,就在多个地方写。反正就是复制粘贴,很方便,但是这样就会导致项目中大量代码冗余和五花八门的调用方法,
增大了维护的成本。所以这里对httpcient的常用操作封装成一个工具类
