 * CORS:

 * Do not do any of below, which are the wrong way to attempt solving the ajax problem:
 * - http.authorizeRequests().antMatchers(HttpMethod.OPTIONS, "/**").permitAll();
 * - web.ignoring().antMatchers(HttpMethod.OPTIONS)
 * <p>
 * Global CORS configuration
 * https://spring.io/blog/2015/06/08/cors-support-in-spring-framework
 * https://docs.spring.io/spring-security/site/docs/current/reference/html/cors.html
 * <p>
 * Solution 1
 * add CrossOrigin annotation to Controller class or methods
 * <p>
 * Solution 2
 * override addCorsMappings(CorsRegistry registry) method of WebMvcConfigurerAdapter class
 * <p>
 * <p>
 * The follow method will override CORS Configuration provided by Spring MVC.
