使用下面的代码将json响应转换为java中的自定义响应对象。

ResponseEntity<Object> response = restTemplate.exchange(
                pathURL,
                HttpMethod.{GET/POST ..},
                createHeader(),
                Object.class
        );

        final List<LinkedHashMap> responseList = objectMapper
                .convertValue(
                        response.getBody(),
                        new TypeReference<List<LinkedHashMap>>() {
                        }
                );

        LinkedHashMap<String, String> responseMap = responseList.get(0);

        CustomResponseObj infoResp = objectMapper.convertValue(responseMap, CustomResponseObj.class);

private HttpEntity<?> createHeader() {
        HttpHeaders headers = new HttpHeaders();
        return new HttpEntity<>(headers);
    }
