列表列字段导出权限控制 === > 针对数据列表的列进行权限控制后,列表导出数据时与列权限相对应 > 需基于列表列字段权限控制已完成 **举例:** 打卡时间字段已做权限控制,在列表中隐藏,则在导出时,也不会导出 ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/50/36/50364f62c7db5d16a31b49a34ec29be6_1138x172.png) ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/f6/ed/f6ed283e425fcde02e07305739cd0e6e_621x165.png) ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/e1/bb/e1bb2a0189a9d88cde63ebdee4880b5f_606x111.png) ### 权限控制步骤 #### 后台导出方法添加权限逻辑,获取需导出的字段,将所有需要导出字段逗号隔开,拼接字符串 ~~~ @RequestMapping(value = "/exportXls") @PermissionData(pageComponent = "jeecg/JeecgDemoList") public ModelAndView exportXls(HttpServletRequest request, JeecgDemo jeecgDemo) { //获取导出表格字段 String exportFields = jeecgDemoService.getExportFields(); return super.exportXls(request, jeecgDemo, JeecgDemo.class, "单表模型",exportFields); } ~~~ ~~~ public String getExportFields() { //获取当前登录人 LoginUser sysUser = (LoginUser) SecurityUtils.getSubject().getPrincipal(); //权限配置列导出示例 List noAuthList = new ArrayList<>(); List exportFieldsList = new ArrayList<>(); //1.此前缀必须与列表字段权限控制前缀一致 String permsPrefix = "testdemo:"; //查询配置菜单有效字段 List allAuth = this.baseMapper.queryAllAuth(permsPrefix); //查询已授权字段 List userAuth = this.baseMapper.queryUserAuth(sysUser.getId(),permsPrefix); //列出未授权字段 for(String perms : allAuth){ if(!userAuth.contains(perms)){ noAuthList.add(perms.substring(permsPrefix.length())); } } //实体类中字段与未授权字段比较,列出需导出字段 Field[] fileds = JeecgDemo.class.getDeclaredFields(); List list = new ArrayList(Arrays.asList(fileds)); for(Field field : list){ if(!noAuthList.contains(field.getName())){ exportFieldsList.add(field.getName()); } } return exportFieldsList != null && exportFieldsList.size()>0 ? String.join(",", exportFieldsList) : ""; } ~~~
