使用REST客户端从JSON获取值

Question

我的api工作正常，我在POSTMAN中测试时确实得到了JSON结果。我在使用REST客户端通过控制器检索JSON值时遇到问题。我正在使用spring和hibernate。

@RequestMapping(value = "/viewForm/{id}")
    public String viewForm(@Valid @PathVariable("id") String id, Model model) {

        RestTemplate restTemplate = new RestTemplate();

        String fooResourceUrl
            = "http://localhost:8080/api/delivery/searchDanceform/"+ id;

        System.out.println(fooResourceUrl);

        ResponseEntity<DanceApplicationForm> rateResponse =
                restTemplate.exchange(fooResourceUrl,
                            HttpMethod.GET, null, DanceApplicationForm.class);
        DanceApplicationForm response = rateResponse.getBody();

        System.out.println(response);
        logger.info("result = {}", response);

        return VIEW_PATH + "dance-profile";

    }

我收到了这个错误，

SEVERE: Servlet.service() for servlet [dispatcher] in context with path [/intranet-web] threw exception [Request processing failed; nested exception is org.springframework.web.client.HttpClientErrorException: 404 null] with root cause

我也尝试过这种方式。

String response = restTemplate.getForObject(fooResourceUrl, String.class);

但仍然无法正常工作。

这是你的处理程序控制器

http://localhost:8080/api/delivery/searchDanceform/

 @RequestMapping(value = "/searchDanceform/{id}")
    public String searchDanceform(@Valid @PathVariable("id") String id, Model model) {
          // do your code and return response




    }
