Spring Boot Static Resources

spring-boot

    <link href="../static/css/guru.css"
          th:href="@{css/guru.css}" rel="stylesheet" media="screen"/>

Notice how the link tag has two href attributes? The first one in normal HTML will be used by the browser when the template is read from the file system. The second with the ‘th’ namespace is used by Thymeleaf when the template is rendered via Spring Boot. In this case a SPeL expression is being used to resolve the path of the static asset under Spring Boot, and this will be used as the path when the template is rendered by Spring Boot for the browser via a request through Tomcat.
