Spring MVC has implicit CORS support, so to use the controller method CORS configuration with @CrossOrigin annotation in your Spring Boot application does not require any specific configuration.

The global CORS configuration can be defined by registering a WebMVCConfigurer bean with a customized addCorsMappings(CorsRegistry) method, as you can see in the code below:

@Configurationpublic class MyConfiguration {     @Bean     public WebMvcConfigurer corsConfigurer() {            return new WebMvcConfigurerAdapter()  {                @Override                public void addCorsMappings(CorsRegistry registry) {                          registry.addMapping("/api/**");                }            };    }}
