SpringMVC 下载XLS文档的设置

此文是关于xls文档下载的，这个文档使用Apache的POI生成，需要的jar包可以从下面地址下载：

下面是controller代码，比上一篇文本的少很多：

    @RequestMapping("/downloadAnnotatorListXls")
    public ModelAndView downloadAnnotatorListXls(HttpServletRequest request,HttpServletResponse response){
        String fileName="annotatorList.xls";
        
        response.reset();// 不加这一句的话会出现下载错误 
        response.setHeader("Content-disposition", "attachment;filename=" + fileName);   // 设定输出文件头   
        response.setContentType("application/vnd.ms-excel");   // 定义输出类型 
        
        try {
            
            HSSFWorkbook xls=service.getAnnotatorListInXls();
            OutputStream ouputStream = response.getOutputStream();   
            xls.write(ouputStream);   
            ouputStream.flush();   
            ouputStream.close();   
              
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(e);
            
            request.setAttribute("error", e.getClass());
            request.setAttribute("reason", e.getMessage());
            StackTraceElement[] arr=e.getStackTrace();
            request.setAttribute("stackTraceElements", arr);
            
            return new ModelAndView("pages/error/index.jsp");
        }
        
        
        return null;
    }

具体xls生成请参考：

public HSSFWorkbook getAnnotatorListInXls() throws Exception{
        StringBuilder sb=new StringBuilder();
        sb.append("    select");
        sb.append("        t1.id,");
        sb.append("        t1.ownerId,");
        sb.append("        t1.ownerName,");
        sb.append("        t1.annotatorId,");
        sb.append("        t1.name,");
        sb.append("        t1.fullName,");
        sb.append("        t1.language,");
        sb.append("        format(t1.planHour,2) as planHour");
        sb.append("    from");
        sb.append("        ownership t1 ");
        sb.append("    order by");
        sb.append("        id");
        String sql=sb.toString();
        
        List<?> ls=this.getJdbcTemplate().query(sql, new NameValueRowMapper());
        
        
        HSSFWorkbook wb = new HSSFWorkbook();
        HSSFSheet sheet = wb.createSheet("sheet1");
        
        // 表头颜色
        HSSFCellStyle blueStyle = wb.createCellStyle();
        blueStyle.setBorderTop(HSSFCellStyle.BORDER_THICK);
        blueStyle.setBorderBottom(HSSFCellStyle.BORDER_THIN);
        blueStyle.setFillForegroundColor(HSSFColor.SKY_BLUE.index);
        blueStyle.setFillPattern(CellStyle.SOLID_FOREGROUND);
        
        // 表头部分"ID,OwnerId,OwnerName,AnnotatorId,Name,FullName,Language,PlanHour
"
        HSSFRow row = sheet.createRow(0);//建立新行
        
        HSSFCell cell =row.createCell((short)0);
        cell.setCellValue("ID");
        cell.setCellStyle(blueStyle);
        
        cell =row.createCell((short)1);
        cell.setCellValue("OwnerId");
        cell.setCellStyle(blueStyle);
        
        cell =row.createCell((short)2);
        cell.setCellValue("OwnerName");
        cell.setCellStyle(blueStyle);
        
        cell =row.createCell((short)3);
        cell.setCellValue("AnnotatorId");
        cell.setCellStyle(blueStyle);
        
        cell =row.createCell((short)4);
        cell.setCellValue("Name");
        cell.setCellStyle(blueStyle);
        
        cell =row.createCell((short)5);
        cell.setCellValue("FullName");
        cell.setCellStyle(blueStyle);
        
        cell =row.createCell((short)6);
        cell.setCellValue("Language");
        cell.setCellStyle(blueStyle);
        
        cell =row.createCell((short)7);
        cell.setCellValue("PlanHour");
        cell.setCellStyle(blueStyle);
        
        short rowNum=1;
        short columnNum=0;
        for(Object obj:ls){
            row = sheet.createRow(rowNum);//建立新行
            columnNum=0;
            
            List<NameValue> lsTemp=(List<NameValue>)obj;
            
            for(NameValue nv:lsTemp){
                cell =row.createCell(columnNum);
                cell.setCellValue(nv.getValue());
                columnNum++;
            }
            
            rowNum++;
        }
        
        
        return wb;
    }
