JeeSite数据权限控制解决方案

支持如下数据范围设置:

 

  1. 所有数据
  2. 所在公司及以下数据
  3. 所在公司数据
  4. 所在部门及以下数据
  5. 所在部门数据
  6. 仅本人数据
  7. 按明细设置(特殊情况下,跨机构授权)
User user = UserUtils.getUser();
// 使用标准查询
DetachedCriteria dc = articleDao.createDetachedCriteria();
dc.createAlias("office", "office").createAlias("user", "user");
dc.add(dataScopeFilter(user, "office", "user"));
List<Entity> list = articleDao.find(page, dc);;
// 使用HQL查询
String hql = "select e from Entity e join e.office o join e.user u where 1=1 ";
hql += dataScopeFilterString(UserUtils.getUser(), "o", "u");
List<Entity> list2 = articleDao.find(page, hql);
