在运行时重新加载CORS设置

Question

I recently implemented a Spring Cloud Config Server . My application (client) is able to retrieve application profiles and refresh them in flight. Unfortunately, CORS settings, which are also declared there, are not reloaded by Spring during runtime. I did a small investigation and check that in terms of refresh everything looks good - ConfigurationPropertiesRebinder rebind() method successfully destroys old bean holding CORS setup and creates a new with up-to-date settings. I also see that Environment bean is holding new settings in propertySources field.

Is there any way to force Spring to reload CORS during runtime or should I need to reload application context?

Answer 1

Use below code for resolve CORS issue.

@Configuration
@EnableWebMvc
class WebConfig implements WebMvcConfigurer {

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