報錯信息：

org.springframework.web.client.UnknownContentTypeException: Could not extract response: no suitable HttpMessageConverter found for response type [class com.xxx] and content type [text/html;charset=utf-8]

異常原因：RestTemplate請求不支持content type [text/html;charset=UTF-8]類型

解決方法：在生成bean時，為其手動補充text/html格式

• java版：

@Bean("restTemplate")
public RestTemplate restTemplate(){RestTemplate restTemplate = new RestTemplate();MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();mappingJackson2HttpMessageConverter.setSupportedMediaTypes(Arrays.asList(MediaType.TEXT_HTML,MediaType.TEXT_PLAIN));restTemplate.getMessageConverters().add(mappingJackson2HttpMessageConverter);return restTemplate;
}

• kotlin版：

@Bean
fun restTemplate(): RestTemplate? {val restTemplate = RestTemplate()val mappingJackson2HttpMessageConverter = MappingJackson2HttpMessageConverter()mappingJackson2HttpMessageConverter.supportedMediaTypes = Arrays.asList(MediaType.TEXT_HTML,MediaType.TEXT_PLAIN)restTemplate!!.messageConverters.add(mappingJackson2HttpMessageConverter)return restTemplate
}
