Usage

Add a CorsBundle to your Application class.

@Override
public void initialize(Bootstrap<MyConfiguration> bootstrap) {
    // ...
    bootstrap.addBundle(new CorsBundle());
}

Implement CorsBundleConfiguration in your Configuration class.

public class MyConfiguration extends Configuration implements CorsBundleConfiguration{

    @Valid
    @NotNull
    private CorsConfiguration corsConfiguration = new CorsConfiguration();

    @JsonProperty("corsConfiguration")
    @Override
    public CorsConfiguration getCorsConfiguration() {
        return corsConfiguration;
    }

    @JsonProperty("corsConfiguration")
    public void setCorsConfiguration(CorsConfiguration corsConfiguration) {
        this.corsConfiguration = corsConfiguration;
    }
}
