ssh 万能类分页系统，可复用！

动态实现分页，可复用，类分页，ssh package com.djh.action.web; import java.io.Serializable; import java.util.List; public class PageBean<DUser> implements Serializable{ /** * */ private static final long serialVersionUID = 1L; private List<DUser> list;//要返回的页面记录列表 private int allRow;//总记录数 private int totalPage;//总页数 private int currentPage;//当前页 private int pageSize;//每页显示的条数 public List<DUser> getList() { return list; } public void setList(List<DUser> list) { this.list = list; } public int getAllRow() { return allRow; } public void setAllRow(int allRow) { this.allRow = allRow; } public int getTotalPage() { return totalPage; } public void setTotalPage(int totalPage) { this.totalPage = totalPage; } public int getCurrentPage() { return currentPage; } public void setCurrentPage(int currentPage) { this.currentPage = currentPage; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } public static long getSerialversionuid() { return serialVersionUID; } /* * 计算总页数，静态方法,供外部直接通过类名调用 */ public static int countTotalPage(final int pageSize, final int allRow){ int totalPage = allRow%pageSize == 0? allRow/pageSize:allRow/pageSize + 1; return totalPage; } /* * 计算当前页开始记录 */ public static int countOffset(final int pageSize, final int currentPage){ int offset = pageSize*(currentPage - 1); return offset; } /* * 计算当前页，默认为第一页 */ public static int countCurrentPage(int page){ final int curPage = (page==0 ? 1:page); return curPage; } @SuppressWarnings("unused") private boolean isFirstPage;//是否为第一页 @SuppressWarnings("unused") private boolean isLastPage;//是否为最后一页 @SuppressWarnings("unused") private boolean hasPreviousPage;//是否有前一页 @SuppressWarnings("unused") private boolean hasNextPage;//是否有下一页 public void init(){ this.isFirstPage = isFirstPage(); this.isLastPage = isLastPage(); this.hasPreviousPage = isHasPreviousPage(); this.hasNextPage = isHasNextPage(); } public boolean isFirstPage(){ return currentPage == 1; } public boolean isLastPage(){ return currentPage == totalPage; } public boolean isHasPreviousPage() { return currentPage != 1; } public boolean isHasNextPage() { return currentPage != totalPage; } }
