Bean for Springboot application that will configure CORS -Sometimes you might need to GET the json code generated in swagger to parse

CorsFilterBean.java

// Append this code to the main class

@Bean
	public CorsFilter corsFilter() {
	    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();

	    // Allow anyone and anything access. Probably ok for Swagger spec
	    CorsConfiguration config = new CorsConfiguration();
	    config.setAllowCredentials(true);
	    config.addAllowedOrigin("*");
	    config.addAllowedHeader("*");
	    config.addAllowedMethod("*");

	    source.registerCorsConfiguration("/v3/api-docs", config);
	    return new CorsFilter(source);
	}

// If the above doesn't work
// ******************************************
