java后端实现Excel数据的导出、解决导出数据会在火狐浏览器乱码的问题

@RestController
public class ExcelDownLoadController {

	@Resource
	private AddCustomerService addCustomerService;

@ApiOperation(value = "新增客户数据", notes = "导出时间范围内新增客户数据")
	@ApiImplicitParams({
	    @ApiImplicitParam(name = "startTime",paramType = "query", value = "开始时间", required = true, dataType = "Date"),
		@ApiImplicitParam(name = "endTime",paramType = "query", value = "结束时间", required = true, dataType = "Date")
	})
	@RequestMapping(value = "/api/fm/addcustomer", method = RequestMethod.GET)
	public void addCustomer(HttpServletResponse response,@RequestParam @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date startTime,@RequestParam @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date endTime) throws IOException {
		 
		List<HashMap<String, Object>> userinfos = addCustomerService.getNewUserInfo(startTime, endTime);
		List<HashMap<String, Object>> merchantinfos = addCustomerService.getNewMerchantInfo(startTime, endTime);
		
		Integer index = 1;
		InputStream is = XlsDownLoadController.class.getClassLoader().getResourceAsStream("export/新增客户数据.xls");	
		Workbook workbook = new HSSFWorkbook(is); 
		Sheet sheetOne = workbook.getSheet("往来单位");
		Sheet sheetTwo = workbook.getSheet("联系方式");
		
		for (HashMap<String, Object> userinfo : userinfos) {
			Row row = sheetOne.createRow(index);
			row.createCell(0).setCellValue(getCellValue(userinfo,"user_id"));
			row.createCell(1).setCellValue(getCellValue(userinfo,"real_name"));
			row.createCell(3).setCellValue("客户");
			row.createCell(4).setCellValue("1");

		String fileName = "("+sdf.format(startTime)+"~"+sdf.format(endTime)+").xls";
		//解决火狐浏览器乱码的问题：Header中填写这个Content-Disposition很关键
		response.setHeader("Content-Disposition", "attachment;filename*=utf-8'zh_cn'"  + URLEncoder.encode("新增客户数据", "UTF-8")+fileName);
		workbook.write(response.getOutputStream());
		workbook.close();
		response.getOutputStream().close();
