DetachedCriteria 实现多表关联，检索条件

DetachedCriteria queryCriteria = DetachedCriteria.forClass(Rsvmain.class);
if (ObjectUtils.isNotEmpty(query.getUnitinfoName())) {
                DetachedCriteria unitinfo = DetachedCriteria.forClass(Unitinfo.class);
                unitinfo.add(Restrictions.like("unitnm", "%" + query.getUnitinfoName() + "%"));
                unitinfo.setProjection(Property.forName("id"));
                queryCriteria.add(Property.forName("unitinfoId").in(unitinfo));
            }
            if (ObjectUtils.isNotEmpty(query.getMemberName())) {
                DetachedCriteria member = DetachedCriteria.forClass(Member.class);
                member.add(Restrictions.disjunction()
                        .add(Restrictions.like("lastnm", "%" + query.getMemberName() + "%"))
                        .add(Restrictions.like("firstnm", "%" + query.getMemberName() + "%"))
                        .add(Restrictions.like("altnm", "%" + query.getMemberName() + "%")));
                member.setProjection(Property.forName("id"));
                queryCriteria.add(Property.forName("memberId").in(member));
            }
            if (ObjectUtils.isNotEmpty(query.getStartdt()) || ObjectUtils.isNotEmpty(query.getEnddt())) {
                DetachedCriteria rsvdtl = DetachedCriteria.forClass(Rsvdtl.class);
                if (ObjectUtils.isNotEmpty(query.getStartdt())) {
                    rsvdtl.add(Restrictions.ge("cidt", query.getStartdt()));
                }
                if (ObjectUtils.isNotEmpty(query.getEnddt())) {
                    rsvdtl.add(Restrictions.le("codt", query.getEnddt()));
                }
                rsvdtl.setProjection(Property.forName("rsvmainId"));
                queryCriteria.add(Property.forName("id").in(rsvdtl));
            }
