我有一个Angular前端、spring云网关和一个spring Web服务。当我尝试通过网关向spring Web服务发送GET/POST数据时，我收到以下错误：CORS error.当直接将数据发送到Web服务时，它工作正常，所以我认为问题出在网关上。
在网关中，我必须以下文件：

@Configuration
@CrossOrigin(origins = "*")
public class SpringCloudConfig {

    @Bean
    public RouteLocator gatewayRoutes(RouteLocatorBuilder builder){
        return builder.routes()
                .route(r -> r.path("/users/**")
                .uri("http://localhost:8081/")
                .id("userService"))

                .route(r -> r.path("/posts/**")
                        .uri("http://localhost:8082/")
                        .id("postService"))

                .route(r -> r.path("/auth/**")
                        .uri("http://localhost:8083/")
                        .id("securityService"))
                .build();
    }

}

**应用程序.属性：**我以为服务器：云：等等等等。会做的伎俩，但没有

server.port=8080
