完成基于struts2的word后台自动生成并且导出操作需要的详细步骤

今天很荣幸又破解一现实难题：自动生成并导出word文档

 

先看页面效果：

                     

word效果：

                                             

                                              

代码：

1. 先搭建struts2项目
2. 创建action，并在struts.xml完成注册
3.

                  <result name="exportFile" type="stream">
                     <param name="contentType">application/octet-stream</param>
                   <param name="inputName">inputStream</param>
                   <param name="contentDisposition">attachment;filename="${fileName}"</param>
                   <param name="bufferSize">4096</param>
               </result>
           </action>
       </package>
   </struts>
