控制器

@PostMapping("/event/confirmation")
  public Mono<CallbackResponse> eventConfirmation(@RequestParam("eventId") String eventId,
      @RequestBody ExecutionSummary execSummary, @RequestHeader("customerCode") String customerCode)
      throws ResourceNotFoundException {
    return eventService
        .updateEvent(eventId, execSummary, serviceAuthClient.getDefaultJwtTokenObserver().getJwtAccessToken())
        .flatMap(event -> {
          return Mono.just(new CallbackResponse(true));
        });
  }

          RequestBuilder requestBuilder = 
                          MockMvcRequestBuilders.post("/event/confirmation")
           .contentType(MediaType.APPLICATION_JSON).header("customerCode", "456")
           .param("eventId", "123")
           .content(objectMapper.writeValueAsString(executionSummary));

        MvcResult result = mvc.perform(requestBuilder).andReturn();
        assertEquals(HttpStatus.OK.value(),result.getResponse().getStatus());

  }
}

当我运行测试时，它实际上是在调用原始服务，而不是使用模拟服务。有人能帮我写一个测试上述控制器的方法。
当我打印模拟服务调用时，它打印在输出下面。
