基于bootstrap + velocity的分页实现

PageBean.java代码

public class PageBean {private int total;private int totalPage;private int pageNum;private int start;private int offset = 4;private List<Integer> pages = new ArrayList<Integer>();private int pre;private int next;public static final int SIZE = 5;public PageBean(int pageNum, int total) {this.pageNum = pageNum;this.total = total;getTotalPage();getStart();getPages();getPre();getNext();}public int getTotal() {return total;}public void setTotal(int total) {this.total = total;}public int getTotalPage() {if(total%SIZE==0) {totalPage = total/SIZE;} else {totalPage = total/SIZE + 1;}return totalPage;}public static int getTotalPage(int total, int size) {int totalPage = 0;if(total%size==0) {totalPage = total/size;} else {totalPage = total/size + 1;}return totalPage;}public int getPageNum() {return pageNum;}public void setPageNum(int pageNum) {this.pageNum = pageNum;}public int getStart() {start = (pageNum-1) * SIZE;return start;}public int getOffset() {return offset;}public void setOffset(int offset) {this.offset = offset;}public List<Integer> getPages() {pages.clear();int s = (pageNum - offset)>0?(pageNum - offset):1;int e = (pageNum + offset)>totalPage?totalPage:(pageNum + offset);for(int i=s; i<=e; i++) {pages.add(i);}return pages;}public void setPages(List<Integer> pages) {this.pages = pages;}public int getPre() {pre = pageNum - 1;return pre;}public void setPre(int pre) {this.pre = pre;}public int getNext() {next = pageNum +1;return next;}public void setNext(int next) {this.next = next;}}

前台velocity代码

<div class="pagination pagination-centered"><ul>#if($pageBean.pageNum==1)<li class="disabled"><a>首页</a></li>#else<li><a href="/app/page.do?pageNum=1">首页</a></li>#end#if($pageBean.pageNum==1)<li class="disabled"><a>«</a></li>#else<li><a href="/app/page.do?pageNum=$pageBean.pre" class="active">«</a></li>#end#foreach($p in $pageBean.pages)#if($p==$pageBean.pageNum)<li class="disabled"><a>$p</a></li>#else<li><a href="/app/page.do?pageNum=$p">$p</a></li>#end#end#if($pageBean.pageNum==$pageBean.totalPage)<li class="disabled"><a>»</a></li>#else<li><a href="/app/page.do?pageNum=$pageBean.next">»</a></li>#end#if($pageBean.pageNum==$pageBean.totalPage)<li class="disabled"><a>末页</a></li>#else<li><a href="/app/page.do?pageNum=$pageBean.totalPage">末页</a></li>#end</ul></div>
