pager-taglib分页标签使用方法

主页：http://jsptags.com/tags/navigation/pager/

pager-taglib是一个JSP分页标签库

可扩展性好，需要后台JAVA分页，前台可以多种风格显示分页

缺点：没有增加样式，需要自己定义

war包可以直接运行，但是demo.jsp代码太多了

新增一个简单的jsp ，清楚些

<%@ page session="false" %>
<%@ taglib uri="/WEB-INF/pager-taglib.tld" prefix="pg" %>

    String position = getParam(request, "position", "top");

    int maxIndexPages = getParam(request, "maxIndexPages", 10);
