Thymeleaf + CSS+SpringBoot

Question

I have a problem with CSS and Thymeleaf.

In my Spring boot app, I have this structure:

• src/main/resource/static/css (for css files)
• src/main/r

Answer 1

Move your template folder right under resources:

• src/main/resource/static/css (for CSS files);
• src/main/resource/templates (for HTML templates).

Then correct the link tag as follows:

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

Answer 2

The main culprit of this behaviour is a custom security configuration which is very likely you are doing in your WebSecurityConfigurerAdapter subclass. If you use SpringBoot 2+ version you should add the following line in your WebSecurityConfigurerAdapter configuration

.requestMatchers(PathRequest.toStaticResources().atCommonLocations()).permitAll()

Answer 3

Move your template folder right under resources:

src/main/resources/static/css (for CSS files);
src/main/resources/templates (for HTML templates).

Then correct the link tag as follows (relative or absolute):

<link href="../css/firstcss.css" rel="stylesheet">
<link href="/css/secondcss.css" rel="stylesheet">

The old solution with static in front doesn't work for me.
