本文章来源 POI导出Word文档—黑壳网

昨天晚上被壳妹，威逼利诱，做点小东西，其中就有一个POI导出Word文档。并且最好不要用freemarker模板导出word文档，只好手动来一个工具类了。
供参考学习

控制层代码

    public class ExportController {

      private static Logger logger = LoggerFactory.getLogger(ExportController.class);

      @RequestMapping("index")
      public String index(HttpServletRequest request, HttpServletResponse response) {
          
          /**
          * context 为以html样式导出到word文档里
          */
          String context = " \n" +
                  "\n" +
                  "\n" +
                  "  \n" +
                  "\"Content-Type\" content=\"text/html; charset=UTF-8\" />\n" +
                  "  \n" +
                  "  \n" +

                  "\n" +
                  "    \n" +
                  "    \n" +
                  "       \"width: 50%;\" align=\"center\"> \n" +
                  "        分  析  报  告\n" +

                  "  \n" +
                  "\n" +
                  "\n";

    /**
    * 创建工具类实例
    */
    ExportUtil exportUtil = new ExportUtil();
  
    /**
    * 调用~~~ 导出word成功
    */
    exportUtil.exportWord(request, response, context);

     return "index";
  }

util类代码

/**

 */
public class ExportUtil {

   private static final Logger logger = LoggerFactory.getLogger(ExportUtil.class);

   public void exportWord(HttpServletRequest request, HttpServletResponse response, String content) {

          try {

              byte b[] = content.getBytes("utf-8"); //这里是必须要设置编码的，不然导出中文就会乱码。
    ByteArrayInputStream bais = new ByteArrayInputStream(b);//将字节数组包装到流中

    /**
   * 关键地方
   * 生成word格式
   */
    POIFSFileSystem poifs = new POIFSFileSystem();
    DirectoryEntry directory = poifs.getRoot();
    DocumentEntry documentEntry = directory.createDocument("WordDocument", bais);
    //输出文件
    String fileName = "wordFileName";
    request.setCharacterEncoding("utf-8");
    response.setContentType("application/msword");//导出word格式
    response.addHeader("Content-Disposition", "attachment;filename=" +
                      new String((fileName + ".doc").getBytes(),
    "UTF-8"));

    OutputStream ostream = response.getOutputStream();
    poifs.writeFilesystem(ostream);
    bais.close();
    ostream.close();
    } catch (Exception e) {
              logger.error("导出出错：%s", e.getMessage());
    }
    }
}
