jsp自定义分页标签
直接就java代码吧package net.eicp.roomally.web.tag;import java.io.IOException;import javax.servlet.jsp.JspException;import javax.servlet.jsp.JspWriter;import javax.servlet.jsp.tagext.BodyContent;import javax.servlet.jsp.tagext.BodyTagSupport;public class PagingTag extends BodyTagSupport {private static final long serialVersionUID = 3803084919005718453L;// 用户请求的methodprivate String method;private boolean isBorder;private String parameters;// 点击时提交处理的url(必须)private String action;// 数据库的数据总条数(必须)private long count;public String getParameters() {return parameters;}public void setParameters(String parameters) {this.parameters = parameters;}// 当前的条数private long index;// 每页的条数private int pageCount;private long next() {long previousIndex = count - count % pageCount;if (index >= previousIndex) {return previousIndex;} else if ((index + pageCount) == count) {return index;}return index + pageCount;}private long previous() {if (index <= 0) {return 0;}return index - pageCount;}/* * 收集参数 */private String parameter() {String para = "";if (!isNull(method)) {para += "&method=" + method;}if (!isNull(parameters)) {para += "&" + parameters;}return para;}/* * 判断是否为空 */private boolean isNull(String name) {return "".equals(name == null ?

然后在WEB-INF下创建一个.tld文件,下面是tld文件的内容，内容里的http://roomally.eicp.net/tag/page就是在jsp页面要通过指令taglib引用的
<div class="quote_title">引用
