1、不用工具类，直接方法导出

@RequestMapping("/exportexcel")
    	public void exportexcel(HttpServletResponse response) {
    		OutputStream oStream = null;
    		try {
    //			创建工作簿
    			HSSFWorkbook wb = new HSSFWorkbook();
    //			创建sheet
    			HSSFSheet sheet = wb.createSheet("列表");
    //			创建表头
    			HSSFRow row = sheet.createRow(0);
    			//创建单元格
    			HSSFCell cell = row.createCell(0);
    			cell.setCellValue("护士id");
    			HSSFCell cell1 = row.createCell(1);
    			cell1.setCellValue("项目");
    			HSSFCell cell2 = row.createCell(2);
    			cell2.setCellValue("时间");
    			HSSFCell cell3 = row.createCell(3);
    			cell3.setCellValue("类别");
    			HSSFCell cell4 = row.createCell(4);
    			cell4.setCellValue("成绩");
    			//创建表头
    			HSSFRow lrows = sheet.createRow(1);
    			HSSFCell lcells = lrows.createCell(0);
    			lcells.setCellValue("导入时请删除本行！！注:需要填写护士id、项目名称、时间、成绩。类别默认为护理部，531就代表是护理部操作，不用改");
    			HSSFRow lrow = sheet.createRow(2);
    			//创建单元格
    			HSSFCell lcell = lrow.createCell(0);
    			lcell.setCellValue("10000");
    			HSSFCell lcell1 = lrow.createCell(1);
    			lcell1.setCellValue("全体护理人员护士条例考试");
    			HSSFCell lcell2 = lrow.createCell(2);
    			lcell2.setCellValue("2018-03-08");
    			HSSFCell lcell3 = lrow.createCell(3);
    			lcell3.setCellValue("531");
    			HSSFCell lcell4 = lrow.createCell(4);
    			lcell4.setCellValue("89");
    			//根据response获取输出流
    			response.setContentType("application/force-download"); // 设置下载类型
    			response.setHeader("Content-Disposition","attachment;filename=sxlb.xls"); // 设置文件的名称
    			oStream = response.getOutputStream(); // 输出流
    			//把工作薄写入到输出流
    			wb.write(oStream);
    			
    		} catch (Exception e) {
    			// TODO: handle exception
    			try {
    				oStream.close();
    			} catch (IOException e1) {
    				e1.printStackTrace();
    			}
    			e.printStackTrace();
    		}
    		
    	}

2、在jsp页面加上方法

<button type="button" onclick="exportexcel()">导出模板</button>
    
        function exportexcel(){
    			window.location.href="hrm/exportexcel.do"
    		}
