Springboot won’t load CSS folders after implementing web security & mvc configuration

I tried to implement this example but in my case, i have some static css files i have to include.

Regarding the css issue i tried putting th:href="@{PATH} attribute on html links but it didn’t work for me.

My application on the security side, works almost as the example above.

In my project instead of being redirected to hello.html i’m being redirected to an image url.

This is the html templates, in which i used Thymeleaf:

  • login.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:th="https://www.thymeleaf.org"

  • Project’s Structure:

enter image description here

Only hello.html home.html and login.html are being used for this example.

Output

This is what the login.html looks like without logincss folder:

And upon successful login i’m being redirected here(instead of hello.html):

enter image description here

How can i correctly refer to the static css and redirect the user to hello.html?

I’m sorry for the long post.

Answer

You need to allow access to logincss and any other static resources (js, images, etc) directories in the Spring Security configuration. In your configure method, add .antMatchers("/logincss/**").permitAll().

Similarly add antMatcher for “/templates/**”.

Reference configuration in Spring Documentation for additional reading here.

As regards redirection on successful login to hello.html, you need to add the configuration for defaultSuccessUrl("/hello.html"). Reference Documentation here.
