Spring. Tomcat. Maximum upload size exceeded

При загрузке файла возникает ошибка Maximum upload size exceeded, хотя в файле application.properties указан максимальный размер файла,

spring.servlet.multipart.max-file-size=15MB
spring.servlet.multipart.max-request-size=15MB

и есть

@Bean
fun multipartResolver(): MultipartResolver? {
    val multipartResolver = CommonsMultipartResolver()
    multipartResolver.setMaxUploadSize(15728640)
    return multipartResolver
}

В чём может быть проблема?
