java调用远程接口方法封装

请求远程接口 get方式

      /**
     * 请求时将请求路径与参数拼装好放入url中传入
     *示例url：InterfaceRequestGet（"http://192.168.100.100:121/Xxx/getxxxx?key1=%s&key2=%s,xxx1,xxx2")
     */
    public List<Map<String,Object>> InterfaceRequestGet(String url){
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.add(HttpHeaders.CONTENT_TYPE, "application/x-www-form-urlencoded");
        HttpEntity<String> httpEntity = new HttpEntity<String>(null, headers);
        log.debug("request："+url);
        ResponseEntity<String> result = restTemplate.exchange(url, HttpMethod.GET, httpEntity, String.class);
        String str=result.getBody();//接口的返回值要以具体的实际为准去解析
        log.debug("response:"+str);
        str=str.substring(str.indexOf("{"),str.lastIndexOf(("}"))+1);
        JSONObject resultJson = JSONObject.parseObject(str);
        JSONArray jsonArray=resultJson.getJSONArray("data");
        List<Map<String,Object>> mapList = (List<Map<String,Object>>) JSONArray.parse(jsonArray.toString());
        return mapList;
    }

请求远程接口 post方式

    /**
     * 请求时将请求路径与参数分开
     *示例：InterfaceRequest("192.168.100.100:121/Xxx/getxxxx", requestBody);
     */
 public String InterfaceRequest(String url, LinkedMultiValueMap<String,String> requestBody){
        //String url="http://192.168.100.202:8081/LesaseQuery.asmx/LeaseQueryBYFWBH";
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        HttpEntity<MultiValueMap<String, String>> httpEntity =
                new HttpEntity<MultiValueMap<String, String>>(requestBody, headers);
        log.debug("request："+url);
        ResponseEntity<String> result = restTemplate.exchange(url, HttpMethod.POST, httpEntity, String.class);
        String str=result.getBody();//接口的返回值要以具体的实际为准去解析
        log.debug("response:"+str);
        str=str.substring(str.indexOf("{"),str.lastIndexOf(("}"))+1);
        return str;
    }
