hibernate一值多字段模糊查询

1. public Page getCoordByPage(Page queryHandler, TCoordinate conditions) {
2. DetachedCriteria dc = DetachedCriteria.forClass(TCoordinate.class);
3. if (conditions.getTAxis() != null) {
4. dc.add(Restrictions.eq("TAxis", conditions.getTAxis()));
5. }
6. if(conditions.getCoordinateName()!=null){
7. dc.add(Restrictions.like("coordinateName", conditions.getCoordinateName(),MatchMode.ANYWHERE).ignoreCase());
8. }
9. if(conditions.getParentCoordinate().getId()!=null){
10. dc.add(Restrictions.eq("parentCoordinate.id", conditions.getParentCoordinate().getId()));
11. }
12. dc.addOrder(Order.desc("addDate"));
13. Page page = this.coordinateDao.getPageByCriteria(queryHandler, dc);
14. return page;
15. }

两个条件之间or的用法【Restrictions.or(lhs, rhs)】：

[java] view plain copy

1. dc.add(Restrictions.or(Restrictions.like("country", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase(),
2. Restrictions.like("pinyin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase()));

超过两个，比如三个条件之间的or【Disjunction disjunction = Restrictions.disjunction();】：

[java] view plain copy

1. if(!ValidateUtils.isEmpty(comm.getCountry())){
2. Disjunction disjunction = Restrictions.disjunction();
3. disjunction.add(Restrictions.like("country", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());
4. disjunction.add(Restrictions.like("pinyin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());
5. disjunction.add(Restrictions.like("jianpin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());
6. dc.add(disjunction);
7. }

8. hibernate 查询match mode的四种模式

   Hibernate 查询MatchMode的四种模式

   MatchMode.START：字符串在最前面的位置.相当于"like ‘key%‘"
   MatchMode.END：字符串在最后面的位置.相当于"like ‘%key‘"
   MatchMode.ANYWHERE：字符串在中间匹配.相当于"like ‘%key%‘"
   MatchMode.EXACT：字符串精确匹配.相当于"like ‘key‘"
