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
Restrictions.like
Restrictions.in
Restrictions.and
Restrictions.or
Restrictions.sqlRestriction
用SQL限定查询
2，QBC常用限定方法
Restrictions.eq --& equal,等于.
Restrictions.allEq --& 参数为Map对象,使用key/value进行多个等于的比对,相当于多个Restrictions.eq的效果
Restrictions.gt --& great-than & 大于
Restrictions.ge --& great-equal &= 大于等于
Restrictions.lt --& less-than, & 小于
Restrictions.le --& less-equal &= 小于等于
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,为空则返回true
Restrictions.isNotNull --& 与isNull相反
Restrictions.sqlRestriction --& SQL限定的查询
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 --& 字符串在中间匹配.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'"
查询年龄在20-30岁之间的所有学生对象
List list = session.createCriteria(Student.class)
.add(Restrictions.between("age",new Integer(20),new Integer(30)).list();
查询学生姓名在AAA,BBB,CCC之间的学生对象
String[] names = {"AAA","BBB","CCC"};
List list = session.createCriteria(Student.class)
.add(Restrictions.in("name",names)).list();
查询年龄为空的学生对象
List list = session.createCriteria(Student.class)
.add(Restrictions.isNull("age")).list();
查询年龄等于20或者年龄为空的学生对象
List list = session.createCriteria(Student.class)
.add(Restrictions.or(Restrictions.eq("age",new Integer(20)),
Restrictions.isNull("age")).list();
--------------------------------------------------------------------
使用QBC实现动态查询
public List findStudents(String name,int age){
Criteria criteria = session.createCriteria(Student.class);
if(name != null){
criteria.add(Restrictions.liek("name",name,MatchMode.ANYWHERE));
if(age != 0){
criteria.add(Restrictions.eq("age",new Integer(age)));
criteria.addOrder(Order.asc("name"));//根据名字升序排列
return criteria.list();
-----------------------------------------------------------------------------------
今天用了写hibernate高级查询时用了Restrictions(当然Expression也是可以以的)这个类.感觉不错.
下面的代码写的不易读.其实核心就是一句
Restrictions.or(Restrictions.like(),Restrictions.or(Restrictions.like,........))
里面的or可以无限加的.还是比较好用
Session session = getHibernateTemplate().getSessionFactory()
.openSession();
Criteria criteria = session.createCriteria(Film.class);
List&Film& list = criteria.add(
Restrictions.or(Restrictions.like("description", key,MatchMode.ANYWHERE),
Restrictions.or(Restrictions.like("name", key,MatchMode.ANYWHERE),
Restrictions.or(
Restrictions.like("direct", key,MatchMode.ANYWHERE),
Restrictions.or(Restrictions.like("mainplay",key,MatchMode.ANYWHERE),
Restrictions.like("filearea", key,MatchMode.ANYWHERE)))))).list();
session.close();

谢谢，很好解决我们的问题
PageOffice插件，挺好使得，可以试试
需要用哪些jar,可以说下吗
哈哈哈，是啊。不用解压，我傻傻的解压出来搞半天。。。
