 编写controller(编写一个集合,展示到前端页面):

 编写test2.jsp(前端页面):

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
<script src="${pageContext.request.contextPath}/statics/js/jquery-3.6.0.js"></script>

<script>
$(function () {
$("#btn").click(function () {
/*
$.post(url,param[可以省略],success)
*/
$.post("${pageContext.request.contextPath}/a2",function (data) {
let html="";
for (let i = 0; i <data.length ; i++) {
html +="<tr>"+
"<td>"+data[i].name+"</td>"+
"<td>"+data[i].age+"</td>"+
"<td>"+data[i].sex+"</td>"+
"</tr>"
}
$("#content").html(html);
})
})
});
</script>
</head>
<body>
<input type="button" value="加载数据" id="btn">
<table>
<tr>
<td>姓名</td>
<td>年龄</td>
<td>性别</td>
</tr>
<tbody id="content">
