Docker化Spring Boot实例化MqttClient时Bean创建异常求助

我在MqttClientService中通过以下方式实例化MqttClient：

public MqttClientService(KipitProperties properties) {

    String connectionString = String.format("%s://%s:%s",
            properties.getMqtt().getProtocol(),
            properties.getMqtt().getUrl(),
            properties.getMqtt().getPort());

    try {
        this.publisher = new MqttClient(connectionString, properties.getMqtt().getPublisher().getId());
    } catch (MqttException ex) {
        log.error(ExceptionUtils.getMessage(ex));
        log.error(ExceptionUtils.getFullStackTrace(ex));
    }
}

应用在本地运行正常，但部署通过jib构建的Docker镜像时出现如下错误：

我推测问题在于MqttClient无法在Docker容器（基础镜像为openjdk:17-oracle）中创建持久化文件。
