我想写一个API在收到请求后返回202 Accepted。然后在那之后，它应该每秒发送n个Post请求，持续halt-time秒。这是我在这个问题上的尝试。

@PostMapping(value = "/stress")
@ResponseStatus(HttpStatus.ACCEPTED)
private Mono<?> stressPostLog(@RequestBody StressTest request) throws InterruptedException {
    return Mono.fromCallable(() -> {
            sendBatchRequest(request);
            return null;
    }).subscribeOn(Schedulers.boundedElastic());
    
}
private void sendBatchRequest(StressTest requestParams) throws InterruptedException {
    successfulRequest.set(0);
    long haltTimeMillis = requestParams.getHalt_time() * 1000;
    log.info("Halt Time Millis = " + haltTimeMillis );
    Integer count = 0;
    long initTime = System.currentTimeMillis();
    long currTime;
    do {
        Thread.sleep(1000); //! Sleep time is subjected to system
        for(int i = 0; i < requestParams.getRequest_per_second(); i++)
        {
            AuditSchema request = AuditSchema.generateRandomValue(requestParams.getRequest_size());
            Mono<?> response = postAndIncrement(request);
            response.publishOn(Schedulers.boundedElastic()).subscribe();
            count++;
        }
        currTime = System.currentTimeMillis();
        log.info("Time duration = " + ( currTime - initTime));
    }while((currTime - initTime) < haltTimeMillis);
    log.info("Request Send = {} and Response Succeed = {}", count, successfulRequest);
}
private Mono<?> postAndIncrement(AuditSchema request) {
    return this.client.post()
            .uri("v1/log")
            .body(BodyInserters.fromValue(request))
            .accept(MediaType.APPLICATION_JSON)
            .exchangeToMono(clientResponse -> {
                log.info("Request suceeded {}", clientResponse.statusCode());
                successfulRequest.getAndIncrement();
                return Mono.empty();
            });
}

但是，调用不会在5s内执行，并且在5s后会因错误而终止

java.lang.IllegalStateException: Timeout on blocking read for 5000000000 NANOSECONDS
