导出按钮所对应的jsp页面userList.jsp

点击导出按钮，跳转对应的js页面。

处理导出功能对应的controller.

/**
     * 导出用户数据
     * @param user
     * @param request
     * @param response
     * @param redirectAttributes
     * @return
     */
    @RequiresPermissions("sys:user:view")
    @RequestMapping(value = "export", method=RequestMethod.POST)
    public String exportFile(User user, HttpServletRequest request, HttpServletResponse response, RedirectAttributes redirectAttributes) {
        try {
            String fileName = "用户数据"+DateUtils.getDate("yyyyMMddHHmmss")+".xlsx";
            Page<User> page = systemService.findUser(new Page<User>(request, response, -1), user);
            new ExportExcel("用户数据", User.class).setDataList(page.getList()).write(response, fileName).dispose();
            return null;
        } catch (Exception e) {
            addMessage(redirectAttributes, "导出用户失败！失败信息："+e.getMessage());
        }
        return "redirect:" + adminPath + "/sys/user/list?repage";
    }

一定记得在对应的实体类中，给实体类的属性加上@ExcelField(title="归属公司", align=2, sort=20)注解
