Springmvc 使用 AbstractExcelView 导出excel

 $("#exportBtn").click(function () {
            location.href = "${pageContext.request.contextPath}/report/export?" + $("form").serialize()
        });

1.新建类继承AbstractExcelView

 import java.io.OutputStream;
 import java.util.Map;
 import javacommon.util.MyUtils;
 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;
 import org.apache.poi.hssf.usermodel.HSSFCell;
 import org.apache.poi.hssf.usermodel.HSSFCellStyle;
 import org.apache.poi.hssf.usermodel.HSSFRow;
 import org.apache.poi.hssf.usermodel.HSSFSheet;
 import org.apache.poi.hssf.usermodel.HSSFWorkbook;
 import org.springframework.web.servlet.view.document.AbstractExcelView;
 public class ViewExcel extends AbstractExcelView {
     @Override
     protected void buildExcelDocument(Map<String, Object> obj,
             HSSFWorkbook workbook, HttpServletRequest request, HttpServletResponse response)
             throws Exception {
         HSSFSheet sheet = workbook.createSheet("list");
         sheet.setDefaultColumnWidth((short) 12);
         HSSFCell cell = getCell(sheet, 0, 0);
         setText(cell, "Spring Excel test");
         HSSFCellStyle dateStyle = workbook.createCellStyle();
         //dateStyle.setDataFormat(HSSFDataFormat.getBuiltinFormat("mm/dd/yyyy"));
         cell = getCell(sheet, 1, 0);
         cell.setCellValue("日期：2008-10-23");
         //cell.setCellStyle(dateStyle);
         getCell(sheet, 2, 0).setCellValue("测试1");
         getCell(sheet, 2, 1).setCellValue("测试2");
         HSSFRow sheetRow = sheet.createRow(3);
         for (short i = 0; i < 10; i++) {
             sheetRow.createCell(i).setCellValue(i * 10);
         }
         String filename = "测试.xls";//设置下载时客户端Excel的名称
         filename = MyUtils.encodeFilename(filename, request);//处理中文文件名
         response.setContentType("application/vnd.ms-excel");
         response.setHeader("Content-disposition", "attachment;filename=" + filename);
         OutputStream ouputStream = response.getOutputStream();
         workbook.write(ouputStream);
         ouputStream.flush();
         ouputStream.close();
     }
 }  

处理中文文件名的方法：

 /**
      * 设置下载文件中文件的名称
      *
      * @param filename
      * @param request
      * @return
      */
     public static String encodeFilename(String filename, HttpServletRequest request) {
       /**
        * 获取客户端浏览器和操作系统信息
        * 在IE浏览器中得到的是：User-Agent=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; Alexa Toolbar)
        * 在Firefox中得到的是：User-Agent=Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.7.10) Gecko/20050717 Firefox/1.0.6
        */
       String agent = request.getHeader("USER-AGENT");
       try {
         if ((agent != null) && (-1 != agent.indexOf("MSIE"))) {
           String newFileName = URLEncoder.encode(filename, "UTF-8");
           newFileName = StringUtils.replace(newFileName, "+", "%20");
           if (newFileName.length() > 150) {
             newFileName = new String(filename.getBytes("GB2312"), "ISO8859-1");
             newFileName = StringUtils.replace(newFileName, " ", "%20");
           }
           return newFileName;
         }
         if ((agent != null) && (-1 != agent.indexOf("Mozilla")))
           return MimeUtility.encodeText(filename, "UTF-8", "B");    

         return filename;
       } catch (Exception ex) {
         return filename;
       }
     }   

2接下来在你的下载 Controller里面返回ModelAndView 即可

 /**
     * 导出Excel
     * @param model
     * @param projectId
     * @param request
     * @return
     */
    @RequestMapping(value="/dcExcel",method=RequestMethod.GET)
     public ModelAndView toDcExcel(ModelMap model, HttpServletRequest request){
        List list = new ArrayList();  //测试数据没有用到
        Map map = new HashMap();
        list.add("test1");
        list.add("test2");
        map.put("list", list);
        ViewExcel viewExcel = new ViewExcel();
        return new ModelAndView(viewExcel, model);
    }  

代码很简单，只实现下载，关于Excel 格式数据方面请参考 poi 框架
