OCP开源项目：Spring Cloud Gateway模块中动态路由的实现

@Component
public class DynamicRouteService {
 
    private final RouteDefinitionWriter routeDefinitionWriter;
    private final ReactiveRouteLocator routeLocator;
 
    @Autowired
    public DynamicRouteService(RouteDefinitionWriter routeDefinitionWriter, ReactiveRouteLocator routeLocator) {
        this.routeDefinitionWriter = routeDefinitionWriter;
        this.routeLocator = routeLocator;
    }
 
    public Mono<Void> addRoute(RouteDefinition routeDefinition) {
        return routeDefinitionWriter.save(Mono.just(routeDefinition)).then();
    }
 
    public Mono<Void> deleteRoute(String id) {
        return routeDefinitionWriter.delete(Mono.just(id)).then();
    }
 
    public Flux<RouteDefinition> getRoutes() {
        return routeDefinitionWriter.getAll();
    }
 
    public Mono<RouteDefinition> getRoute(String id) {
        return routeDefinitionWriter.get(Mono.just(id));
    }
}

这段代码定义了一个服务类DynamicRouteService，它使用构造器注入方式注入了RouteDefinitionWriter和ReactiveRouteLocator。提供了添加路由、删除路由、获取所有路由和获取指定路由的方法。这个类可以用于动态管理Spring Cloud Gateway的路由规则。
