Springmvc 使用 AbstractExcelView 导出excel

页面调用： 

1. $("#exportBtn").click(function () {  
2.  location.href = "${pageContext.request.contextPath}/report/export?" + $("form").serialize()  
3.        });   

 实现Spring mvc 下Excel导出 

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);   
   }
