本文实例讲述了Hibernate分页的两种实现方法。分享给大家供大家参考,具体如下:
1. criteria分页
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
|
public Page getPage( int currentPage, int pageSize,Criterion...crts){
Criteria c=session.createCriteria(House. class );
List list= null ;
for ( int i = 0 ; i < crts.length; i++) {
c.add(crts[i]);
}
c.setProjection(Projections.rowCount());
int totalRecord=Integer.valueOf(c.uniqueResult().toString());
c.setProjection( null );
c.setFirstResult((pageSize)*(currentPage- 1 ));
c.setMaxResults(pageSize);
list=c.list();
Page page= new Page();
page.setCurrentPage(currentPage);
page.setPageSize(pageSize);
page.setTotalRecord(totalRecord);
page.setList(list);
return page;
}

2. hql分页
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

public Page getPage( int currentPage, int pageSize,String hql,Object...args){
String countHql= "select count(*) " +hql.substring(hql.indexOf( "from" ));
Session session=HibernateUtil.getInstance().getSession();
Query query=session.createQuery(countHql);
for ( int i = 0 ; i < args.length; i++) {
query.setParameter(i, args[i]);
}
int totalRecord=Integer.valueOf(query.uniqueResult()+ "" );
query=session.createQuery(hql);
for ( int i = 0 ; i < args.length; i++) {
query.setParameter(i, args[i]);
}
query.setFirstResult(pageSize*(currentPage- 1 ));
query.setMaxResults(pageSize);
List<House> list=(List<House>)query.list();
Page page= new Page();
page.setCurrentPage(currentPage);
page.setPageSize(pageSize);
page.setTotalRecord(totalRecord);
page.setList(list);
return page;
}

希望本文所述对大家基于Hibernate框架的Java程序设计有所帮助。
