Error: No 'Access-Control-Allow-Origin' header is present on the requested resource. even after including the CORS support

I am trying to write an Api in spring boot and am trying to access it using frontend I have written. I have added the Cors support, still I am getting this error: *

Failed to load http://localhost:8080/: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access.

My Cors support in main file is:

@Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/greeting-javaconfig").allowedOrigins("*");
            }
        };
    }

I am using apache server for frontend.

Can sopmeone help me with the issue?
