hibernate一值多字段模糊查询

Posted 2020-07-22 Sincerity

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.           
7.         if(conditions.getCoordinateName()!=null){  
8.             dc.add(Restrictions.like("coordinateName", conditions.getCoordinateName(),MatchMode.ANYWHERE).ignoreCase());  
9.         }  
10.   
11.         if(conditions.getParentCoordinate().getId()!=null){  
12.             dc.add(Restrictions.eq("parentCoordinate.id", conditions.getParentCoordinate().getId()));  
13.         }  
14.   
15.         dc.addOrder(Order.desc("addDate"));  
16.         Page page = this.coordinateDao.getPageByCriteria(queryHandler, dc);  
17.         return page;  
18.     }  

 

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.               
4.             disjunction.add(Restrictions.like("country", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());  
5.             disjunction.add(Restrictions.like("pinyin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());  
6.             disjunction.add(Restrictions.like("jianpin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());  
7.               
8.             dc.add(disjunction);  
9.         }  

10.  

    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‘"
