ssh中的HibernateDaoSupport 实现分页

数据库为mysql5.0 表名为Author

struts2+hibernate3.0+spring3.0

首先是在自动生成的DAO里面加上如下代码

public List findAll(){

String sql="FROM Author order by author_id";

return getHibernateTemplate().find(sql);

}

public List findAllByPage( final int pageNow, final int pageSize){

List list = (List) getHibernateTemplate().execute(

new HibernateCallback() {

int size=pageNow*pageSize-pageSize;

public Object doInHibernate(Session session)

throws HibernateException {

Query q =session.createQuery("from Author order by author_id");

q.setFirstResult(size);

q.setMaxResults(pageSize);

List cats = q.list();

return cats;

}

});//内部类，返回一个List

return list;

}

然后就是在action里面定义

public int pageNow = 1 ; //初始化为1,默认从第一页开始显示

public int pageSize =3 ; //每页显示5条记录 并生成get，set方法

public int getPageNow() {

return pageNow;

}

public void setPageNow(int pageNow) {

this.pageNow = pageNow;

}

public int getPageSize() {

return pageSize;

}

public void setPageSize(int pageSize) {

this.pageSize = pageSize;

} 最后就是前台jsp的调用

<s:url id="url_pre" value="List.action">

<s:param name="pageNow" value="pageNow-1"></s:param>

</s:url>

<s:url id="url_next" value="List.action">

<s:param name="pageNow" value="pageNow+1"></s:param>

</s:url>

<s:form action="List" theme="simple">

转到第<s:textfield name="pageNow"></s:textfield>页

<span><s:submit value=''GO'' name=''cndok''/></span>

</s:form>

<s:a href="%{url_pre}">上一页</s:a>

<s:a href="%{url_next}">下一页</s:a>
