引入mavin

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

yml配置

thymeleaf:
    cache: false # 方便前端可以及时拿到更新数据
    check-template-location: true
    prefix: classpath:/templates/
    suffix: .html
    encoding: utf-8
    mode: HTML5

如果通过拦截器访问thymeleaf丢失样式、脚本

 <link rel="icon" href="../assets/img/favicon.ico" th:href="@{~../assets/img/favicon.ico}">
<link rel="stylesheet" type="text/css" href="css/webbase.css" th:href="@{~/css/webbase.css}" />
<link rel="stylesheet" type="text/css" href="css/pages-login-manage.css" th:href="@{~/css/pages-login-manage.css}" />

使用th:href在路径前面加一个~即可解决
