在JavaWeb开发中，分页是常见的功能，用于在大量数据中进行导航。"pager-taglib"是一个专门用于实现分页效果的标签库，它提供了一种方便的方式来在JSP页面上显示分页链接，而无需编写大量的HTML和Java代码。下面我们将详细探讨如何使用pager-taglib分页以及其主要特性。 `pager-taglib`的核心在于其提供的自定义JSP标签，这些标签简化了分页界面的创建。例如，`<pager:pagelist>`用于显示分页链接，`<pager:page>`则用来跳转到特定页码。通过配置这些标签，开发者可以轻松定制分页样式，包括页码展示、上一页/下一页按钮、总页数显示等。为了使用`pager-taglib`，你需要将对应的jar包（通常名为`pager-taglib-x.x.x.jar`）添加到项目的类路径中。这可以通过在`WEB-INF/lib`目录下放入jar包或者在构建工具如Maven或Gradle的依赖管理中进行设置来实现。在JSP页面中引入`pager-taglib`，需要在页面顶部添加以下行： ```jsp <%@ taglib prefix="pager" uri="http://jeesite.com/tags/pager" %> ``` 这将定义一个前缀`pager`，之后在页面中可以通过这个前缀调用标签库中的标签。然后，你需要在后台Java代码中计算出分页所需的数据。这通常涉及到数据库查询，如使用Spring Data JPA或MyBatis进行分页查询。例如，你可以创建一个服务方法，返回带有当前页码、每页大小、总记录数和实际数据的Page对象。在JSP页面上使用`pager:pagelist`和`pager:page`标签来渲染分页组件。基本结构可能如下： ```jsp <pager:pagelist page="${page}" var="p" total="${page.totalPages}"> <a href="#" onclick="jumpPage('${p}')">${p}</a> </pager:pagelist> ``` 这里`page`是从后台传递过来的Page对象，`var="p"`表示将每一页的页码赋值给变量`p`，`total="${page.totalPages}"`表示总页数。 `pager:page`标签可以用于创建跳转链接，比如： ```jsp <pager:page page="1" /> <pager:page page="2" />  ``` `page`属性指定要跳转到的页码。除了基础的分页功能，`pager-taglib`还提供了许多可配置的属性，如`style`（样式）、`firstPageText`（首页文本）、`lastPageText`（尾页文本）等，允许开发者自定义分页的外观和行为。在提供的`PageDemo`示例中，你应该能够找到一个完整的分页应用实例，包括JSP页面、控制器和相关配置。通过研究这个例子，你可以更好地理解`pager-taglib`的工作原理，并将其应用到自己的项目中。 `pager-taglib`是一个强大的工具，可以帮助JavaWeb开发者快速实现高效且美观的分页功能。其易用性、灵活性和丰富的定制选项使得它成为处理大量数据时的理想选择。通过学习和实践，你可以掌握这个库的使用，提升你的Web应用的用户体验。

It can emulate all currently known paging styles with minimal effort. It also includes re-usable index styles that emulate the search result navigators of popular web sites such as <font color="#0000cc">G</font><font color="#cccc00">oo</font><font color="#0000cc">g</font><font color="#00cc00">l</font><font color="#cc0000">e</font><small><sup>SM</sup></small>, AltaVista® and Yahoo!. The Pager Tag Library does most of the work for you by dynamically organizing your data set into pages and generating a browsable index with virtually any look desired.</p> <p> <hr> <a name="license"></a> <h2>License</h2> <p> <pre> /* * Pager Tag Library * * Copyright (C) 2002 James Klicman <a href="mailto:james@jsptags.com"><james@jsptags.com></a> * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2.1 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
