I'm new to Spring Boot and my problem is that I have Spring Boot project and I am intending to view my HTML pages with Thymeleaf but Spring can't resolve my JavaScript and CSS files.
Full picture of my IDE:
Those are my Thymeleaf configurations
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.cache=true
This is my HTML page head:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
>
<head>
<title>404 Page</title>

You should use relative path to your JavaScript and CSS files:
<link href="../../static/css/style.css" rel="stylesheet" type="text/css" media="screen"/>
or you can use th:href Thymeleaf's tag as well:
<link th:href="@{css/style.css}" href="../../static/css/style.css"
rel="stylesheet" type="text/css" media="screen"/>
