add multiple cross origin urls in spring boot

Question

I found an example on how to set cors headers in spring-boot application. Since we have many origins, I need to add them. Is the following valid?

@Configuration
         


        

Answer 1

Create your custom annotation and annotate the API with that.

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
@CrossOrigin
public @interface CrossOriginsList {

    public String[] crossOrigins() default  {

            "http://domain1.com", "http://domain1.com"
            "http://domain1.com", "http://domain1.com"
            // Pass as many as you want
    };
}

And now Annotate your API with this custom Annotation

@CrossOriginsList
    public String methodName() throws Exception
{
        //Business Logic
}

Worked perfectly fine for me.!!
