Spring boot 网络客户端'；强制关闭事件循环不接受其注册任务的通道'；

我开发了一个与Auto2客户端\u凭据集成的WebClient

@Autowired
private WebClient webClient;
List <Device> deviceList = new ArrayList<Device>();


public void getDeviceData(String macAddress) {
    logger.info("** start getDeviceData . **");

    String formatMac = macAddress.replaceAll("(.{2})", "$1"+":").substring(0,17);
    String request = "{ \"cmMac\": \""+formatMac+"\" }";
     
     webClient.post()
        .uri("https:......")
        .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE).header(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_VALUE)
        .body(Mono.just(request), String.class)
        .attributes(ServerOAuth2AuthorizedClientExchangeFilterFunction.clientRegistrationId("...."))
        .retrieve()
        .bodyToMono(String.class)
        .doOnError(e -> logger.error(e.getMessage()))
        .doOnNext(s ->  {
            JsonObject convertedObject = new Gson().fromJson(s, JsonObject.class);
            Device device = new Device();
            device.setMacAddress(macAddress);
            deviceList.add(device);
        }).block();
}


@Override
public void run(String... args) throws Exception {
    getDeviceData("xxxxxxxx");
    
    for (Iterator iterator = deviceList.iterator(); iterator.hasNext();) {
        Device device = (Device) iterator.next();
        logger.info(device.getMacAddress());
    }
}

@Autowired
私人网络客户端网络客户端；
List deviceList=new ArrayList（）；
public void getDeviceData（字符串macAddress）{
logger.info（“**启动getDeviceData.*”；
字符串formatMac=macAddress.replaceAll（“（{2}）”，“$1”+“：”）。子字符串（0,17）；
字符串请求=“{\“cmMac\”：\”+formatMac+“\”}”；
webClient.post（）
.uri（“https:……”）
.header（HttpHeaders.CONTENT\u TYPE，MediaType.APPLICATION\u JSON\u VALUE）.header（HttpHeaders.ACCEPT，MediaType.APPLICATION\u JSON\u VALUE）
.body（Mono.just（请求）、String.class）
.attributes（ServerOAuth2AuthorizedClientChangeFilterFunction.clientRegistrationId（“..”）
.retrieve（）
.bodyToMono（String.class）
.doon错误（e->logger.error（e.getMessage（）））
.doOnNext（s->{
JsonObject convertedObject=new Gson（）.fromJson（s，JsonObject.class）；
设备=新设备（）；
设备。设置macAddress（macAddress）；
添加（设备）；
}).block（）；
}
@凌驾
公共无效运行（字符串…参数）引发异常{
获取设备数据（“xxxxxxxx”）；
for（Iterator Iterator=deviceList.Iterator（）；Iterator.hasNext（）；）{
设备设备=（设备）迭代器.next（）；
logger.info（device.getMacAddress（））；
}
}

因为我还在开发阶段，所以我使用STS来运行程序。一般来说，该函数工作良好，它将检索访问令牌，然后对在线服务进行post调用

当我需要更改代码并保存文件时，程序将失败，并出现以下错误：

我是WebClient的新手，不知道此错误的根本原因是什么

你知道这个场景有什么问题吗

谢谢
