HQL运算符 QBC运算符 含义 = Restrictions.eq() 等于equal <> Restrictions.ne() 不等于not equal > Restrictions.gt() 大于greater than >= Restrictions.ge() 大于等于greater than or equal < Restrictions.lt() 小于less than <= Restrictions.le() 小于等于less than or equ
HQL运算符 QBC运算符 含义 = Restrictions.eq() 等于equal <> Restrictions.ne() 不等于not equal > Restrictions.gt() 大于greater than >= Restrictions.ge() 大于等于greater than or equal < Restrictions.lt() 小于less than <= Restrictions.le() 小于等于less than or equ
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
