JSP分页要用2个方法，我怀疑我写的不对，有没有源码？
首先得来个实体类（存储分页的信息，我起名称叫Page）
import java.util.ArrayList;
import java.util.List;public class Page {
private int totalPage = 1;/**
* 前一页
*/
private int prePage = 1;/**
* 下一页
*/
private int nextPage = 1;/**
* 总记录数
*/
private int totalRec = 0;/**
* 默认每页记录数
*/
private final int defaultPageSize = 10;/**
* 每页记录数
*/
private int pageSize = defaultPageSize;/**
* 当前页码
*/
private int pageIndex = 1;/**
* 全部页码，从1开始
*/
private int[] pageNumbers;public int getPageIndex() {
return pageIndex;
}public void setPageIndex(int pageIndex) {
this.pageIndex = pageIndex > 0 ? pageIndex : 1;
}public int getNextPage() {
return nextPage;
}public void setNextPage(int nextPage) {
this.nextPage = nextPage > this.totalPage ? this.totalPage : nextPage;
}public int getPageSize() {
return pageSize;
}public void setPageSize(int pageSize) {
this.pageSize = pageSize > 0 ? pageSize : 10;
}public int getPrePage() {
return prePage;
}public void setPrePage(int prePage) {
this.prePage = prePage < 1 ? 1 : prePage;
}public int getTotalPage() {
return totalPage;
}public void setTotalPage(int totalPage) {
this.totalPage = totalPage > 0 ? totalPage : 1;
}public int getTotalRec() {
return totalRec;
}public void setTotalRec(int totalRec) {
this.totalRec = totalRec > -1 ? totalRec : 0;
}public int[] getPageNumbers() {
return pageNumbers;
}public void setPageNumbers(int[] pageNumbers) {
this.pageNumbers = pageNumbers;
}
}
==============实体类有了，我们得在写一个公共的DAO方法（也就是每一个用到分页的地方都会调用这个）================public List findPageByQuery(final String queryString,
final Object[] parameters, final Page pageInfo) {
return (List) getHibernateTemplate().execute(new HibernateCallback()//这里使用了匿名内部类
{
public Object doInHibernate(Session session)//Spring进行事务维护 省去每次创建session和关闭session
throws HibernateException
{
Query query = session.createQuery(queryString);
if (parameters != null)
{
for (int i = 0; i < parameters.length; i++)
{
query.setParameter(i, parameters[i]);
}
}
ScrollableResults sr = query.scroll();
sr.last();
int totalCount = sr.getRowNumber();
int startIndex = (pageInfo.getPageIndex() - 1)
* pageInfo.getPageSize();
query.setMaxResults(pageInfo.getPageSize());
query.setFirstResult(startIndex);
int totalRec = totalCount + 1;
pageInfo.setTotalRec(totalRec);
int totalPage = (totalRec % pageInfo.getPageSize() == 0) ? (totalRec / pageInfo
.getPageSize())
: (totalRec / pageInfo.getPageSize()) + 1;
int[] pageNumbers = new int[totalPage];
for (int i = 0; i < totalPage; i++)
{
pageNumbers[i] = (i + 1);
}
pageInfo.setPageNumbers(pageNumbers);
pageInfo.setTotalPage(totalPage);
pageInfo.setPageSize(pageInfo.getPageSize());
pageInfo.setPageIndex(pageInfo.getPageIndex());
pageInfo.setPrePage(pageInfo.getPageIndex() - 1);
pageInfo.setNextPage(pageInfo.getPageIndex() + 1);
return query.list();
}
}, true);
}
=================至此我们的工作就完成了一半了 ，接下了就改写具体的方法了，来调用我们的公工分页方法public List getUU(int lexample,Page pageInfo)
{
/*ApplicationContext context = new ClassPathXmlApplicationContext(
"applicationContext.xml");
dao = (DaoImpl) context.getBean("Dao");
System.out.print(dao);*/ //自己测试时候可以使用
List list = null;
if (pageInfo == null)
pageInfo = new Page();
try
{
hql="SELECT exa FROM Example exa WHERE 1=1 AND exa.LExample="+lexample;
list = this.getCommonDAO().findPageByQuery(hql, null, pageInfo);
} catch (Exception ex)
{
System.out.println(ex);
}
return list;
}=============接下来就是action中调用了===============public ActionForward getMore(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
ExampleForm exampleForm = (ExampleForm) form;// TODO Auto-generated method stub
List list = new ArrayList();
try
{
//pageInfo = (PageInfo) request.getAttribute("pageInfo");
String type=request.getParameter("type");
//类别编号
int typeId=0;
//页码编号
String page=request.getParameter("page");
if(page==null)
{page="1"; }
if(type==null) {
//默认显示女的
type="2";
}
System.out.println("action...........................");
pageInfo.setPageIndex(Integer.parseInt(page));
pageInfo.setPageSize(20);
typeId=Integer.parseInt(type);
// pageInfo.setPageIndex(Integer.parseInt(request.getParameter("Index")));
list = this.exampleBiz.getUU(typeId,pageInfo);
if(list.size()!=0)
{
request.setAttribute("list", list);
request.setAttribute("pageInfo", pageInfo);
}
}catch
(Exception ex)
{
ex.printStackTrace();
}
return mapping.findForward("more");
}======下面是页面，我们的工作马上就完了。<%String nowPage ;
String type;
int total;
nowPage=request.getParameter("page");
if(nowPage==null)
{nowPage="1";}
type=request.getParameter("type"); //这个是我项目中的类别，没必要的
if(type==null) {
type="2";
}
int curPage=Integer.parseInt(nowPage);
int typeId=Integer.parseInt(type);
System.out.println(typeId+"------------------------------------");
if((Page)request.getAttribute("pageInfo") == null){
total = 1;
} else {
total = ((Page)request.getAttribute("pageInfo")).getTotalPage();
if(curPage>((Page)request.getAttribute("pageInfo")).getTotalPage()) {
curPage=total;
}
}
%>
${example.account.name }

OK!，现在我们的分页就行了，赶快试试吧！
excel vba 怎么查看当前工作表可打印的总页数，和某一页的所在的页数，

SQL存储过程 ')' 附近有语法错误。
执行存储过程的时候，参数不能是GETDATE()这样的函数，需要定义一个变量，把函数的值放到变量中才可以。
exec InsertData 'sdf','sefe' ,'frv' ,'adfe' ,getdate(),'saefa' ,'aea' ,'1';
你可以试试，把getdate()换了，就不是报这个错误了，你要用getdate()，就在过程里面定义变量，赋值为getdate()
