Spring Cloud微服务网关Zuul动态路由配置优化和手动触发路由刷新

        // 手动触发路由刷新事件
        SpringApplication.run(SpringApplication.class, new DefaultApplicationArguments(server.getAdditionalProfiles()));
    }

    private Predicate<ServerWebExchange> createPredicate(String path) {
        // 此处应该是构建Predicate的逻辑，用于匹配请求路径
        return exchange -> false; // 示例返回false，实际应根据path构建正确的Predicate
    }

    private Function<Predicate<ServerWebExchange>, Mono<ResponseEntity<String>>> createLocation(String url) {
        // 此处应该是构建Location的逻辑，用于代理请求
        return predicate -> Mono.just(ResponseEntity.ok("Mocked Location")); // 示例返回Mocked Location，实际应该代理请求到指定的url
