Hibernate条件查询(DetachedCriteria)

Hibernate条件查询(DetachedCriteria)



方法 说明
Restrictions.eq ＝
Restrictions.allEq 利用Map来进行多个等于的限制
Restrictions.gt ＞
Restrictions.ge ＞＝
Restrictions.lt ＜
Restrictions.le ＜＝
Restrictions.between BETWEEN
Restrictions.like LIKE
Restrictions.in in
Restrictions.and and
Restrictions.or or
Restrictions.sqlRestriction 用SQL限定查



MatchMode类包含的各个静态常量实例

匹配模式
举例

MatchMode.START
Expression.like(“name”,”y”, MatchMode.START)

姓名以y开头

MatchMode.END
Expression.like(“name”,”y”, MatchMode. END)

姓名以y结尾

MatchMode.ANYWHERE
Expression.like(“name”,”y”, MatchMode. ANYWHERE)

姓名中包含y

MatchMode.EXACT
Expression.like(“name”,”y”, MatchMode. EXACT)

精确匹配，姓名必须为y






示例：


view source print?01 DetachedCriteria detachedCrit = DetachedCriteria.forClass(User.class);

02 detachedCrit.addOrder(Order.asc("uname"));  //按照姓名排序

03  

04 if (user!=null && user.getUname()!=null&& user.getUname().trim().length()>0) //姓名查询条件

05     detachedCrit.add(Restrictions.like("uname", user.getUname().trim(), MatchMode.ANYWHERE));

06 if (user!=null && user.getUloginId()!=null && user.getUloginId().trim().length()>0)  //身份证号查询条件

07     detachedCrit.add(Restrictions.like("uloginId", user.getUloginId().trim(), MatchMode.ANYWHERE));

08 if(user!=null && user.getType()!=null && user.getType()!=0) {

09     detachedCrit.add(Restrictions.eq("type", user.getType()));

10 }
