(原)仿HttpClient实现HTTP上传
话不多说了，大家看代码吧

模拟上传提交，发送端

测试的时候用apache common中的fileupload组件接收
<servlet>    <description></description>    <display-name>BigFileUploadServlet</display-name>    <servlet-name>BigFileUploadServlet</servlet-name>    <servlet-class>org.test.BigFileUploadServlet</servlet-class>    <init-param>      <param-name>workDir</param-name>      <param-value>E:/temp/</param-value>    </init-param>    <init-param>      <param-name>destDirPath</param-name>      <param-value>E:/fileTemp/</param-value>    </init-param>  </servlet>  <servlet-mapping>    <servlet-name>BigFileUploadServlet</servlet-name>    <url-pattern>/BigFileUploadServlet</url-pattern>  </servlet-mapping>
