    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/ajax").allowedOrigins("*").allowedMethods("POST");
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedMethods("POST", "GET", "PUT", "OPTIONS", "DELETE")
                .maxAge(3600)
                .allowCredentials(true);
