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

# 第二步：引入相关依赖 #

`pom.xml`

# 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>
    	
    	<link href="../static/asserts/css/bootstrap.min.css" th:href="@{/webjars/bootstrap/4.0.0/css/bootstrap.css}" rel="stylesheet">
    	
    	<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";

# 相关配置 #

#thymeleaf
    spring.thymeleaf.encoding=UTF-8
    spring.thymeleaf.suffix=.html
    #默认严格检查
    #spring.thymeleaf.mode=HTML5
    #非严格检查
    spring.thymeleaf.mode=LEGACYHTML5
