通过${}和*{}的方式来读取表单类对象
<!DOCTYPE html>
<!-- 需要添加
<html xmlns:th="http://www.thymeleaf.org">
这样在后面的th标签就不会报错
-->
<html xmlns:th="http://www.thymeleaf.org">
<head lang="en">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title th:text="${username}">xx</title>
</head>
<body>
<h1 th:text="${username}">Hello World</h1>
<h1>获取对象信息</h1>
<h2>1、通过直接访问对象的方式</h2>
<p th:text="${userInfo.username}"></p>
<p th:text="${userInfo.password}"></p>
<h2>2、通过th:object访问对象的方式</h2>
<div th:object="${userInfo}">
<p th:text="*{username}"></p>
<p th:text="*{password}"></p>
</div>
<h1>表单提交</h1>
<!-- 表单提交用户信息,注意字段的设置,直接是*{} -->
<form action="#" th:action="@{/add}" th:object="${userInfo}" method="post">
<input type="text" th:field="*{username}" />
<input type="text" th:field="*{password}" />
<input type="submit" />
</form>
</body>
