spring - Autowiring 参数作为bean声明参数

Question

我有

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

但是我想拥有一个动态派生的值，而不是http:://localhost:8081/，例如:

@Bean
public RouteLocator gatewayRoutes(RouteLocatorBuilder builder,
                                  @Autowired val discoveryService: DiscoveryService) {
    return builder.routes()
                  .route(r -> r.path("/employee/**")
                               .uri(discoveryService.getHost())
                               .id("employeeModule"))

这可能吗？如何更改语法以自动连接DiscoveryService？

像这样尝试:

    RouteLocatorBuilder.Builder routes = builder.routes();
    discoveryClient.getServices().forEach(service->routes.route(r -> r.path("/"+service+"/**")
            .uri("lb://"+service).id(service)));
    return routes.build();
