Spring mvc 下导出Excel文件

1.新建类继承AbstractExcelView

Java代码

    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：

Java代码

    /**  
         * 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

Java代码

/**
    * 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);
   }
