我有下面的代码来提交一个post http调用
HttpHeaders headers = new HttpHeaders();headers.set(TENANT_ID_HEADER, event.getTenantId());HttpEntity<InputObj> requestEntity = new HttpEntity<>(inputObj, headers);ResponseEntity<Object> responseEntity = restTemplate.exchange(url,HttpMethod.POST,requestEntity,Object.class);
字符串
调用成功到达服务器，并返回200成功代码
ResponseEntity.ok().body("Successfully handled the request");
型
在调用完成后，我一直收到以下错误
Exception while performing api call with message : Error while extracting response for type [class java.lang.Object] and content type [application/json]; nested exception is org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unrecognized token 'Successfully': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false'); nested exception is com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'Successfully': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')

我尝试使用我自己的RestTemplate与转换器，而不是默认的org.springframework.web.client;，但我仍然得到相同的错误

我假设你返回的响应头为“ContentType”application/json，这使得HttpMessageConverterExtractor选择一个json HttpMessageConverter来读取响应，而你的响应体不是有效的json，因此出现了异常。你应该将响应头“ContentType”改为“text/plain”。为了更好的可读性和可维护性，考虑使用ResponseEntity来接受响应。
