spring-boot中使用web-client将文本/HTML响应解析为xml

Question

我正在调用一个API以内容类型“text/html”返回xml响应。当我试图在xml类中解析响应时，我得到了错误消息：

Content type 'text/html' not supported for bodyType=Response

API实际响应

<?xml version='1.0' encoding='UTF-8'?>
<response version="1.0">
    <responseCode>200</responseCode>
    <responseMsg>some message</responseMsg>
</response>

我添加了自定义编解码器来解决这个问题，但不知何故它不起作用。当我添加到json解码错误时：

JSON decoding error: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')

下面是我的代码：API调用

return webClient.get()
            .uri { builder ->
                builder.path("/apiPath")
                    .queryParams(queryParams)
                    .build()
            }
            .retrieve()
            .onStatus({ it != HttpStatus.OK }) {
                RuntimeException("").toMono()
            }
            .bodyToMono(Response::class.java)
            .doOnError {
                logger.error { "Error" }
            }.block()

    @Bean
    fun webClient(): WebClient = WebClient.builder()
        .exchangeStrategies(ExchangeStrategies.builder().codecs(this::acceptedCodecs).build())
        .baseUrl("apiUrl")
        .build()

    private fun acceptedCodecs(clientCodecConfigurer: ClientCodecConfigurer) {
        clientCodecConfigurer.customCodecs().register(Jackson2JsonEncoder(ObjectMapper(), TEXT_HTML))
        clientCodecConfigurer.customCodecs().register(Jackson2JsonEncoder(ObjectMapper(), TEXT_HTML))
    }

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "response")
data class Response(
    @XmlElement
    val responseCode: String = "2000",
    @XmlElement
    val responseMsg: String = "OK",
)

clientCodecConfigurer.defaultCodecs().jaxb2Decoder(Jaxb2XmlDecoder())
clientCodecConfigurer.defaultCodecs().jaxb2Encoder(Jaxb2XmlEncoder())

message : Content type 'text/html' not supported for bodyType=Response

Answer 1

默认情况下，Jaxb2XmlDecoder默认构造函数没有“text/html”。您需要使用Jaxb2XmlDecoder(mimetype...supportedMimeTypes）来传递它，例如：

clientCodecConfigurer.defaultCodecs().jaxb2Decoder(
Jaxb2XmlDecoder(MimeTypeUtils.APPLICATION_XML, MimeTypeUtils.TEXT_XML, MediaType("application", "*+xml"), MimeTypeUtils.TEXT_HTML))
