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

For some reason, if still somebody not able to bypass CORS, write the header which browser wants to access your request.

Add this bean inside your configuration file.

@Bean
public WebSecurityConfigurerAdapter webSecurity() {
    return new WebSecurityConfigurerAdapter() {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.headers().addHeaderWriter(
                    new StaticHeadersWriter("Access-Control-Allow-Origin", "*"));


        }
    };
}

This way we can tell the browser we are allowing cross-origin from all origin. if you want to restrict from specific path then change the "*" to {'http://localhost:3000',""}.
