Java 简单的Excel导出案例

简单的导出案例，案例使用了Apache POI库来实现Excel导出功能。最后接口会输出流给前端

不说了，直接上代码

	//excel导出
	public boolean expAdviceExcel(HttpServletRequest request, JSONObject form, HttpServletResponse response) throws IOException {
		
		try {
            Date date = new Date();
            SimpleDateFormat time = new SimpleDateFormat("yyyy-MM-dd");
            response.reset();
            response.setContentType("APPLICATION/OCTET-STREAM");
            // 设置http响应头信息，告诉浏览器这个文件的名字和类型
            response.setHeader("Content-Disposition", "attachment; filename=" + java.net.URLEncoder.encode(time.format(date) + "意见反馈.xls","UTF-8")); 
        
            //获取数据
            List<AdviceResult> list = this.downExcel(request, form, response);
            HSSFWorkbook workbook = new HSSFWorkbook();
            int rowNum = 0;
            HSSFSheet hssfSheet = workbook.createSheet(time.format(date) + "意见反馈");
            Row row = hssfSheet.createRow(rowNum++);
            //Excle每列的标题
            row.createCell(0).setCellValue("用户名称");
            row.createCell(1).setCellValue("联系方式");
            row.createCell(2).setCellValue("操作菜单");
            row.createCell(3).setCellValue("操作时间");
            row.createCell(4).setCellValue("是否满意");
            row.createCell(5).setCellValue("反馈意见");
            if (list != null && list.size() > 0) {
                for (AdviceResult adviceResult : list) {
                    Row row1 = hssfSheet.createRow(rowNum++);
                    row1.createCell(0).setCellValue(adviceResult.getUsername());
                    row1.createCell(1).setCellValue(adviceResult.getTele());
                    row1.createCell(2).setCellValue(adviceResult.getMenu());
                    row1.createCell(3).setCellValue(adviceResult.getCreatetime());
                    row1.createCell(4).setCellValue(adviceResult.getIfSatisfied());
                    row1.createCell(5).setCellValue(adviceResult.getResultcontent());
                }
            }
            workbook.write(response.getOutputStream());//保存Excel文件
            response.getOutputStream().flush();
            response.getOutputStream().close();
            workbook.close();
        } catch (Exception e) {
           
        }
	
		return true;
	}
