If you don't care to have your static resources authenticated, you could do this:

import static org.springframework.boot.autoconfigure.security.servlet.PathRequest.toStaticResources;

public class SecurityConfig extends WebSecurityConfigurerAdapter {
...
    @Override
    public void configure(WebSecurity webSecurity) throws Exception {
        webSecurity

                .requestMatchers(toStaticResources().atCommonLocations());
    }

}

and in your application.properties:

spring.resources.cache.cachecontrol.max-age=43200

See ResourceProperties.java for more properties that can be set.
