自己添加一个 converter 也就两三行代码：

override fun configureMessageConverters(converters: MutableList<HttpMessageConverter<*>>) {
    super.configureMessageConverters(converters)

    converters += MappingJackson2HttpMessageConverter().apply {
        objectMapper = ObjectMapper().registerModule(KtormModule())
    }
}
