Restrictions.like(属性名, 查询条件的值, 匹配方式)：
Restrictions.in(属性名, 查询条件的值, 匹配方式)：
Restrictions.eq(属性名, 查询条件的值, 匹配方式)：
CriteriaQuery常用的查询限制方法
Restrictions.eq() equal，=
Restrictions.allEq() 参数为Map对象，使用key/value进行多个等于的对比，相当于多个Restrictions.eq()的效果
Restrictions.gt() greater-than, >
Restrictions.lt() less-than, <
Restrictions.le() less-equal, <=
Restrictions.between() 对应SQL的between子句
Restrictions.like() 对应SQL的like子句
Restrictions.in() 对应SQL的in子句
Restrictions.and() and关系
Restrictions.or() or关系
Restrictions.isNull() 判断属性是否为空，为空返回true，否则返回false
Restrictions.isNotNull() 与Restrictions.isNull()相反
Order.asc() 根据传入的字段进行升序排序
Order.desc() 根据传入的字段进行降序排序
MatchMode.EXACT 字符串精确匹配，相当于“like ‘value‘”
MatchMode.ANYWHERE 字符串在中间位置，相当于“like ‘%value%‘”
MatchMode.START 字符串在最前面的位置，相当于“like ‘value%‘”
MatchMode.END 字符串在最后面的位置，相当于“like ‘%value‘”
public List search(TblFwxx condition) {
Session session = this.getSession();
Criteria c = session.createCriteria(TblFwxx.class);
if (null != condition) {
if (condition.getTitle() != null && !condition.getTitle().equals("")) {
c.add(Restrictions.like("title", condition.getTitle(), MatchMode.ANYWHERE));
}
}
c.addOrder(Order.asc("fwid"));
return c.list();
}
