Spring Boot w/ JSP - Not finding CSS files

Question

This is a spring boot app using jsp I've tried many solutions, but I can't seem to get CSS integrated with my JSP files. My JSP files are under /WEB-INF/jsp and my css files are in /resources/static/css.

^ The first one doesn't work, but the second one with the link works.

Application.properties file:

#
# MVC Properties
#
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
server.servlet.context-path=/tfhk
spring.resources.chain.strategy.content.enabled=true
spring.resources.chain.strategy.content.paths=/**

Project structure: link to project structure

Try this in your view:

<link href="/css/main.css" rel="stylesheet">

Also somewhere in your config do this (in spring security context if using it):

private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
        "classpath:/META-INF/resources/", "classpath:/resources/",
        "classpath:/static/", "classpath:/public/"
};

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/**")
            .addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);
}
