1、Download 'Binary' package of the latest official release from the project download page.

There should be 7 jars in total (components marked with (*) include additional features and are optional) on the classpath.

• commons-logging-x.x.x.jar
• commons-codec-x.x.x.jar
• httpcore-x.x.x.jar
• httpclient-x.x.x.jar
• httpmime-x.x.x.jar (*)
• httpclient-cache-x.x.x.jar (*)
• fluent-hc-x.x.x.jar (*)
  2、把这几个.jar文件放到Java\jdk1.7.0_17\jre\lib\ext目录下面，不同的安装版本可能有差异。

  3、引用，右键点击工程名->bulid paths->add external Archives->选择刚才添加的.jar文件即可。
