Java Spring网关RouteLocator空指针异常

在检查时，我发现路由在开始时为空：

reactor.core.Exceptions$ErrorCallbackNotImplemented: java.lang.NullPointerException: The mapper returned a null Publisher
Caused by: java.lang.NullPointerException: The mapper returned a null Publisher

专用流量路由；

有人能帮我解决这个问题吗？我的任务是在启动事件时将路由从数据库动态加载到spring gateway。

一旦我提供了构造函数，问题就解决了：

private Flux<Route> route;

private Flux<Route> route;

@Autowired
    public RefreshableRoutesLocator(@NonNull final RouteLocatorBuilder builder,
            @NonNull final GatewayRoutesRefresher gatewayRoutesRefresher) {
        this.builder = builder;
        this.gatewayRoutesRefresher = gatewayRoutesRefresher;
        clearRoutes();
    }
