錯誤
no suitable HttpMessageConverter found for response type and content type [text/html;charset=UTF-8]
這邊調用的時候使用了RestTemplate
使用過程
RestTemplate restTemplate = new RestTemplate();
String payUrlFinal = "http://127.0.0.1/pay?orderId=1";
PayResponse payResponse = restTemplate.getForObject(payUrlFinal, PayResponse.class);下麵是我請求的路徑
@GetMapping("/pay")
@ResponseBody
public PayResponse pay(@RequestParam("orderId") String orderId){
//1.查詢訂單
OrderDTO orderDTO = orderService.findOne(orderId);
if(Objects.isNull(orderDTO)){
//訂單不存在
throw new SellException(ResultEnum.ORDER_NOT_EXIST);
}
//發起支付
PayResponse payResponse = payService.create(orderDTO);
return payResponse;
}調用之後程式報以下錯誤
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [class com.lly835.bestpay.model.PayResponse] and content type [text/html;charset=UTF-8]] with root cause

at java.lang.reflect.Method.invoke(Method.java:498)解決方案：
我們繼承 MappingJackson2HttpMessageConverter 併在構造過程中設置其支持的 MediaType 類型即可：
public class WxMappingJackson2HttpMessageConverter extends MappingJackson2HttpMessageConverter {
public WxMappingJackson2HttpMessageConverter(){
List<MediaType> mediaTypes = new ArrayList<>();
mediaTypes.add(MediaType.TEXT_PLAIN);
mediaTypes.add(MediaType.TEXT_HTML); //加入text/html類型的支持
setSupportedMediaTypes(mediaTypes);// tag6
}
}然後把這個 WxMappingJackson2HttpMessageConverter 追加到 RestTemplate 的 messageConverters 消息轉換鏈中去：
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new WxMappingJackson2HttpMessageConverter());
String payUrlFinal = "http://127.0.0.1/pay?orderId=1";
PayResponse payResponse = restTemplate.getForObject(payUrlFinal, PayResponse.class);具體原因分析可參照下麵的地址：
