如何压缩 8 种以上不同类型的单声道

How to zip more than 8 different types of mono

我正在尝试同时拨打 9 api 电话。所有这些调用都会 return 不同的响应对象。在此之前我们有 8 个 api 调用,因为这些单声道是不同的类型,所以我使用 Mono.zip 如下所示。

Mono<ResponseEntity<Service1Response>> monoService1 = callService1();
Mono<ResponseEntity<Service2Response>> monoService2 = callService2();
...
Mono<ResponseEntity<Service3Response>> monoService7 = callService7();
Mono<ResponseEntity<Service4Response>> monoService8 = callService8();

MixResponse mix = Mono.zip(monoService1, monoService2, monoService3, monoService4, monoService5, monoService6, monoService7, monoService8).flatMap(response -> {
  MixResponse mixResp = new MixResponse();
  mixResp.setResponse1(response.getT1().getBody());
  mixResp.setResponse2(response.getT2().getBody());
  mixResp.setResponse3(response.getT3().getBody());
  mixResp.setResponse4(response.getT4().getBody());
  mixResp.setResponse5(response.getT5().getBody());
  mixResp.setResponse6(response.getT6().getBody());
  mixResp.setResponse7(response.getT7().getBody());
  mixResp.setResponse8(response.getT8().getBody());
  return Mono.just(mixResp);
})).block();

但现在我们又多了一项服务,Mono.zip 最多只支持 8 个单声道。除了 Mono.zip 之外,还有什么我可以在我的情况下使用的吗?对不起,如果这个问题看起来很愚蠢。我是 spring-webflux 的新手。提前致谢。

您可以使用 Mono.zipIterable 作为参数和组合器函数来组合结果并转换为特定类型:

<R> Mono<R> zip(final Iterable<? extends Mono<?>> monos, Function<? super Object[], ? extends R> combinator)


List<Mono<? extends ResponseEntity<?>>> requests = List.of(
        monoService1, 
        monoService2, 
        monoService3, 
        monoService4
);

Mono.zip(requests, responses -> {
    MixResponse mixResp = new MixResponse();
    mixResp.setResponse1(((ResponseEntity<Service1Response>) responses[0]).getBody());
    mixResp.setResponse2(((ResponseEntity<Service2Response>) responses[1]).getBody());
    mixResp.setResponse3(((ResponseEntity<Service3Response>) responses[2]).getBody());
    mixResp.setResponse4(((ResponseEntity<Service4Response>) responses[3]).getBody());
    return mixResp;
});
