本文整理了Java中rx.Observable.mergeWith()方法的一些代码示例，展示了Observable.mergeWith()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Observable.mergeWith()方法的具体详情如下：
包路径：rx.Observable
类名称：Observable
方法名：mergeWith

Observable.mergeWith介绍

[英]Flattens this and another Observable into a single Observable, without any transformation.

You can combine items emitted by multiple Observables so that they appear as a single Observable, by using the mergeWith method. Scheduler: mergeWith does not operate by default on a particular Scheduler.

代码示例来源：origin: vert-x3/vertx-examples

@Override
 public void start() throws Exception {
  HttpClient client = vertx.createHttpClient();
  HttpClientRequest req = client.request(HttpMethod.GET, 8080, "localhost", "/");
  req.toObservable().

    // Status code check and -> Observable<Buffer>
    flatMap(resp -> {
     if (resp.statusCode() != 200) {
      throw new RuntimeException("Wrong status code " + resp.statusCode());
     }
     return Observable.just(Buffer.buffer()).mergeWith(resp.toObservable());
    }).

    // Reduce all buffers in a single buffer
    reduce(Buffer::appendBuffer).

    // Turn in to a string
    map(buffer -> buffer.toString("UTF-8")).

    // Get a single buffer
    subscribe(data -> System.out.println("Server content " + data));

  // End request
  req.end();
 }
}
