title: How can I return a Mono<Map<String, Flux<Integer>>> response in Spring Webflux?
body: <p>So right now, I am returning a response looking like</p>
  
  <pre><code>    @GetMapping("/integers")
      @ResponseStatus(code = HttpStatus.OK)
      public Mono&lt;Map&lt;String, Flux&lt;Integer&gt;&gt;&gt; getIntegers() {
          Mono&lt;Map&lt;String, Flux&lt;Integer&gt;&gt;&gt; integers = 
                 Mono.just(Map.of("Integers", integerService.getIntegers()));
          return integers;
      }
  </code></pre>
  
  <p>which gives me a response of </p>
  
  <pre><code>{"Integers":{"scanAvailable":true,"prefetch":-1}}
  </code></pre>
  
  <p>where I expected it to stream the <code>Flux&lt;Integer&gt;</code> part as well, but it didn't. How would I do this in Spring webflux?</p>
