第一步：在IDEA中使用Spring Initializr快速创建SpringBoot，添加Web模块

这里写图片描述

第二步：引入相关依赖

第三步：使用Thymeleaf以及引入js

html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Signin Template for Bootstrap</title>
    <!-- Bootstrap core CSS -->
    <link href="../static/asserts/css/bootstrap.min.css" th:href="@{/webjars/bootstrap/4.0.0/css/bootstrap.css}" rel="stylesheet">
    <!-- Custom styles for this template -->
    <link href="../static/asserts/css/signin.css" th:href="@{/asserts/css/signin.css}" rel="stylesheet">
</head>
<body>
</body>
</html>

PS：这里th标签会覆盖相应的属性值

注意：只需要将需要Thymeleaf渲染的文件放到/templates下即可交由Thymeleaf引擎渲染

原理：

@ConfigurationProperties(
    prefix = "spring.thymeleaf"
)
public class ThymeleafProperties {
    private static final Charset DEFAULT_ENCODING;
    public static final String DEFAULT_PREFIX = "classpath:/templates/";
    public static final String DEFAULT_SUFFIX = ".html";
    private boolean checkTemplate = true;
    private boolean checkTemplateLocation = true;
    private String prefix = "classpath:/templates/";
    private String suffix = ".html";
    private String mode = "HTML";
