调用方法如下

@RequestMapping(value = "/jira/exportExcelNew.do", method = RequestMethod.GET)
        @ResponseBody
        public void exportExcel(HttpServletRequest request, HttpServletResponse response) {
            //获取数据
            List<BackLogForPdu> list = testBootService.getBacklog(10005);
    
            //excel标题
            String[] title = {"PDU", "Backlog数"};
    
            //excel文件名
            String fileName = "Backlog信息表" + System.currentTimeMillis() + ".xls";
            //sheet名
            String sheetName = "学生信息表";
            String[][] content = null;
    
            for (int i = 0; i < list.size(); i++) {
                content[i] = new String[title.length];
                BackLogForPdu obj = list.get(i);
                content[i][0] = obj.getPname().toString();
                content[i][1] = obj.getBacklognum().toString();
            }
    
    //创建HSSFWorkbook
            HSSFWorkbook wb = ExcelExport.getHSSFWorkbook(sheetName, title, content, null);
    
    //响应到客户端
            try {
                this.setResponseHeader(response, fileName);
                OutputStream os = response.getOutputStream();
                wb.write(os);
                os.flush();
                os.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
        //发送响应流方法
        public void setResponseHeader(HttpServletResponse response, String fileName) {
            try {
                try {
                    fileName = new String(fileName.getBytes(), "ISO8859-1");
                } catch (UnsupportedEncodingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                response.setContentType("application/octet-stream;charset=ISO8859-1");
                response.setHeader("Content-Disposition", "attachment;filename=" + fileName);
                response.addHeader("Pargam", "no-cache");
                response.addHeader("Cache-Control", "no-cache");
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
