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

#### 使用方法

        if (file.exists()) {

        }

}
