Spring webclient在尝试转换BodyToMono时引发不支持的mediatype异常，POST请求

Question

webClient.post()
.uri(“some url”)
.body(Mono.just(request))
.retrieve()
**.bodyToMono<UUID>()**
.awaitSingle()

如果我试图转换成字符串，它工作得很好。下面的代码

webClient.post()
.uri(“some url”)
.body(Mono.just(request))
.retrieve()
**.bodyToMono<String>()**
.awaitSingle()

我期待API的响应如下

"response": {
"headers": {
  "Content-Type": "text/plain;charset=UTF-8"
},
"status": 200,
"body": "6ea4c979-5e05-4e72-9007-c4644bef5672"

}

WebClient.builder()
                .baseUrl(BASE_URL)
                .clientConnector(new ReactorClientHttpConnector(httpClient))
                .exchangeStrategies(ExchangeStrategies.builder().codecs(this::acceptedCodecs).build())
                .build();


private void acceptedCodecs(ClientCodecConfigurer clientCodecConfigurer) {
        clientCodecConfigurer.customCodecs().register(new Jackson2JsonEncoder(new ObjectMapper(), TEXT_HTML));
        clientCodecConfigurer.customCodecs().register(new Jackson2JsonDecoder(new ObjectMapper(), TEXT_HTML));
    }
