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

I also had messages like No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access.

I had configured cors properly, but what was missing in webflux in RouterFuncion was accept and contenttype headers APPLICATION_JSON like in this piece of code:

@Bean
RouterFunction routes() {
    return route(POST("/create")
                              .and(accept(APPLICATION_JSON))
                              .and(contentType(APPLICATION_JSON)), serverRequest -> create(serverRequest);
}
