If you are using Spring Security ver >= 4.2 you can use Spring Security's native support instead of including Apache's:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

The example above was copied from a Spring blog post in which you also can find information about how to configure CORS on a controller, specific controller methods, etc. Moreover, there is also XML configuration examples as well as Spring Boot integration.
