我先给出 jsp

<ec:table

rowsDisplayed="5"
>
<ec:row>

提交给的Action
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
ListForm listForm = (ListForm) form;
Context context = new HttpServletRequestContext(request);
LimitFactory limitFactory = new TableLimitFactory(context);
TableLimit limit = new TableLimit(limitFactory);
limit.setRowAttributes(Integer.MAX_VALUE, 5); //关键得出 extremecomponents limit
PageBean page = new PageBean();
System.out.println(limit.getCurrentRowsDisplayed()+":limit");
page.setPageSize(limit.getCurrentRowsDisplayed()); //ec通过limit对象传递pageSize给PageBean
page.setPage(limit.getPage());//ec通过limit对象传递pageNo给PageBean
request.setAttribute("table",page.getList());
request.setAttribute("totalRows", new Integer(page.getCount()));
return mapping.findForward("list");
}
提交 bean
package test;

import java.util.Hashtable;
import java.util.List;
import java.util.Map;
public class PageBean {
static ArrayList arr1 = new ArrayList();
static {
for(int i=0;i<1000;i++){
Map map = new Hashtable();
map.put("name",i+"liukaiyi");
map.put("pass",i+"123");
arr1.add(map);
}
}
//仿照 数据 *************************************
private int count = 1000; // 记录总数
private int pageSize = 10; // 每页显示记录数
private int pageCount = 0; // 总页数
private int page = 1; // 当前页数
public int getCount() {
return count;
}
public void setCount(int count) {
if (pageSize != 0) {
pageCount = count / pageSize;
if (count % pageSize != 0) {
pageCount++;
}
}
this.count = count;
}
public int getPage() {
return page;
}
public void setPage(int page) {
this.page = page;
}
public int getPageCount() {
return pageCount;
}
public void setPageCount(int pageCount) {
this.pageCount = pageCount;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public List getList(){ //提交 给 List 显示的 数据********************
int st = (getPage()-1)*getPageSize()-1 ;
int end = st+getPageSize() +1;
System.out.println("bean "+st+":"+end);
List arr = arr1.subList(st,end);
return arr ;
}
}
