今天基于layui实现了将查询出的数据进行分页显示，具体效果图：
话不多说，直接上代码：
jsp文件：
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Layui</title>
<meta name="renderer" content="webkit">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
<link rel="stylesheet" href="lib/layui/css/layui.css" media="all">
<!-- 注意：如果你直接复制所有代码到本地，上述css路径需要改成你本地的 -->
</head>
<body>
<table class="layui-hide" id="test"></table>
<script src="lib/layui/layui.js" charset="utf-8"></script>
<!-- 注意：如果你直接复制所有代码到本地，上述js路径需要改成你本地的 -->
<script>
layui.use('table', function(){
var table = layui.table;
table.render({
elem: '#test'
,method:"post"
,cache:false
,url:'CourseServlet?method=fenye'
//数据总数，从服务端得到 发送数据用where
//示例：,where{"a":b}
,cols: [[
{field:'id', 80, title: 'ID', sort: true}
,{field:'username', 80, title: '用户名'}
,{field:'sex', 80, title: '性别', sort: true}
,{field:'city', 80, title: '城市'}
,{field:'sign', title: '签名', minWidth: 150}
,{field:'experience', 80, title: '积分', sort: true}
,{field:'score', 80, title: '评分', sort: true}
,{field:'classify', 80, title: '职业'}
,{field:'wealth', 135, title: '财富', sort: true}
]]
,page: true
});
});
</script>
</body>
</html>

数据库表就不放了，按照jsp界面的数据或者dao层数据建表即可
