 * org.apache.http.client.HttpClient 与 org.apache.commons.httpclient.HttpClient 区别
 * commons.httpclient-3.1.jar这个jar包是依赖了httpcore，commons-logging，commons-codec这三个jar包。而在commons-httpclient.jar包在使用过程中，需要依赖commons-logging.jar和commons-codec.jar，
 * 这个httpclient4.2.1.jar就相当于集合了以前的commons-httpclient，commons-logging，commons-codec，这三个jar包，减少了繁琐的导入jar包的过程，现在只需导入一个httpclient.jar就可以使用了。
