使用RestTemplate解析JSON时的问题

Question

我试图使用restTemplate.exchange（）方法解析来自服务的JSON响应。但由于解析错误而失败。

Java代码

        RestTemplate restTemplate = new RestTemplate();

        HttpHeaders headers = new HttpHeaders();
        headers.setAccept (Arrays.asList(MediaType.APPLICATION_JSON));
        headers.set("Token", "********");
        System.out.println("***************************");
        System.out.println(headers.toString());
        HttpEntity<String> entity = new HttpEntity<String>("", headers);

        ResponseEntity<SATCHBResponse> result = restTemplate.exchange(<>, HttpMethod.GET, entity, SATCHBResponse.class);

        System.out.println(result.getBody());*
