一个JSP分页代码，JSP分页代码,package com.

package com.page;public class PageUtil { // 每页显示的条数 private int pageSize; // 总共的条数 private int recordCount; // 当前页面 private int currentPage; public PageUtil(int pageSize, int recordCount, int currentPage) {  this.pageSize = pageSize;  this.recordCount = recordCount;  setCurrentPage(currentPage); } // 构造方法 public PageUtil(int pageSize, int recordCount) {  this(pageSize, recordCount, 1); } // 总页数 public int getPageCount() {  // 总条数/每页显示的条数=总页数  int size = recordCount / pageSize;  // 最后一页的条数  int mod = recordCount % pageSize;  if (mod != 0)   size++;  return recordCount == 0 ? 1 : size; } // 包含，起始索引为0 public int getFromIndex() {  // System.out.println("from index:"+(currentPage-1) * pageSize);  return (currentPage - 1) * pageSize; } // 不包含 public int getToIndex() {  // System.out.println("to index:"+Math.min(recordCount, currentPage *  // pageSize));  return Math.min(recordCount, currentPage * pageSize); } // 得到当前页 public int getCurrentPage() {  return currentPage; } // 设置当前页 public void setCurrentPage(int currentPage) {  int validPage = currentPage <= 0 ? 1 : currentPage;  validPage = validPage > getPageCount() ? getPageCount() : validPage;  this.currentPage = validPage; } // 得到每页显示的条数 public int getPageSize() {  return pageSize; } // 设置每页显示的条数 public void setPageSize(int pageSize) {  this.pageSize = pageSize; } // 得到总共的条数 public int getRecordCount() {  return recordCount; } // 设置总共的条数 public void setRecordCount(int recordCount) {  this.recordCount = recordCount; }}

下面的代码是放在jsp里面的

<%PublishersDAO dao = PublishersDAO.getInstance();List records = dao.getModels();String pageStr = request.getParameter("page");int currentPage = 1;if (pageStr != null)currentPage = Integer.parseInt(pageStr);PageUtil pUtil = new PageUtil(10, records.size(), currentPage);currentPage = pUtil.getCurrentPage();%>

                                ---------下面这个是放在有变量的上面-----------------------------------------------------------------------------------------

<%for (int i = pUtil.getFromIndex(); i < pUtil.getToIndex(); i++) {PublisherModel model = (PublisherModel) records.get(i);%>中间是删除修改之类的代码<%}%>

                                ----------这个是结尾的--------------------------------------------------------------------------------------------------------
