Resolving exception from handler [null]: org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported

Question

I have spring boot mvc with a little jpa back for training in this system. I have stylese with connected via thymeleaf links:

<link rel="stylesheet" data-th-href="@{/bs/dist/css/bootstrap.css}">
<link rel="stylesheet" data-th-href="@{/htmlElements/myElements.css}">

this is my project structure

Yesterday everything was working fine, but today I don't see my styles at all. After some researches I get this data:

direct link to http://localhost:8080/htmlElements/myElements.css do not response.
next I restarted my app with DEBUG enabled, and saw that

So, i can't understand what the matter. I do not touch any spring boot autoconfig things. I think i should reconfigure WebMvcConfigurer.class with addResourceHandlers() its method, but i cant find correct guide how to realise it with spring boot.

I can make css like usual @GetMapping with proper position at "/templates", but it bad idea?

UPDATE | PARTIALLY SOLVED i found 1 contoller with @PostMapping without value. Remove it.Restart - styles appears. Then I add this @PostMapping() to the method of @Controller class and do not see those bug. So if anyone get the same problem: restart ide -> then check ur controllers. thx 4 help guys

If you want to access the resource files like CSS etc the you should add configuration for it in you configuration class, to redirect such request to show the files content.

Currently there is no mapping for request. try adding below code in Configuration.java file that is annotated with @Configuration .

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry.addResourceHandler("/css/**").addResourceLocations("/WEB-INF/web/static/css/");
    registry.addResourceHandler("/js/**").addResourceLocations("/WEB-INF/web/static/js/");
    registry.addResourceHandler("/images/**").addResourceLocations("/WEB-INF/web/static/images/");
}

Please map the file location in the above code as per your path.
