用RestTemplate碰到的问题

给请求加上头信息

    Request request = new Request();

　　 HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.add("accept", "application/json");
    requestHeaders.add("content-type", "application/json");
    requestHeaders.add("content-length", "256");
    requestHeaders.add("authorization", authorization);
    requestHeaders.setContentType(MediaType.APPLICATION_JSON)
　　 HttpEntity<?> httpEntity = new HttpEntity<Object>(request, requestHeaders);
　　

　　　 ResponseEntity<Response> response = restTemplate.exchange(url, HttpMethod.POST, httpEntity, Response.class);
　　   return response.getBody();

有些请求是键值对的形式，用request的方法或封装HttpEntity也传不进去参数，可以尝试用下面的方法：

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
    map.add("shortcut", shortcut);
    map.add("_api_key", apikey);
DefaultResponse response = restTemplate.postForObject(url, map, DefaultResponse.class);

从远程获取的list用resttemplate转成相应的对象

ObjectMapper mapper = new ObjectMapper();
DefaultResponse defaultResponse = rehabilitationProxy.getServiceDate();
List<Resource> resources =
        (List<Resource>) defaultResponse.getData();
for (int i = 0; i < resources.size(); i++) {
    Resource resource = mapper.convertValue(resources.get(i), Resource.class);
}
