Spring CORS No 'Access-Control-Allow-Origin' header is present

Question

I am getting the following problem after porting web.xml to java config

No \'Access-Control-Allow-Origin\' header is present on the requested resource. Origi         


        

Answer 1

Following on Omar's answer, I created a new class file in my REST API project called WebConfig.java with this configuration:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

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

This allows any origin to access the API and applies it to all controllers in the Spring project.
