Criteria用法的小结

前几天做项目的时候，用到了Creiteria来查询和分页。实在好用。但本人愚笨，用了不少时间，今天有空把用法记录下来，备忘。

多条件循环查询：

String comId = param.getCompany().getId();
        List depts = param.getDepartments();
        String name = param.getName() + "";
        String phoneNum = param.getPhoneNum() + "";
        Criteria criteria = getIBaseDAO().getCurrentSession().createCriteria(TCompanyDirectory.class);

        if (depts != null) {
            Disjunction dis = Restrictions.disjunction();//多条件查询准备
            for (TDepartment dept : depts) { //查询所有外键部门Id符合条件的员工
                dis.add(Restrictions.eq("department.id", "" + dept.getId()));
            }
            criteria.add(dis);
        }

        criteria.add(Restrictions.eq("company.id", comId));
        criteria.add(Restrictions.like("name", "%" + name + "%"));
        criteria.add(Restrictions.like("mobilePhone", "%" + phoneNum + "%"));
        criteria.addOrder(Order.asc("name"));

分页

        criteria.setProjection(null);
        SearchCompanyDirectoryResult searchResult = new SearchCompanyDirectoryResult();
        searchResult.setTotalCount(criteria.list().size());
        criteria.setFirstResult(beginIndex);
        criteria.setMaxResults(everyPage);
        searchResult.setCds(criteria.list());
        searchResult.setListDepts(param.getCompany().getDepartments());
        return searchResult;
