调用方法

LinkedHashMap resultMap = sendHttp(reqBody);

方法

private LinkedHashMap sendHttp(Map body) {
  String uurl = url+ "WfTask/startAndCommitProcessByToken";
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        headers.set("Accept-Charset", "UTF-8");
        Object data = JSON.toJSON(body);
        HttpEntity entity = new HttpEntity<Object>(data, headers);
        ResponseEntity<Map> response = restTemplate.exchange(uurl, HttpMethod.POST, entity, Map.class);
        LinkedHashMap responseMap = (LinkedHashMap) response.getBody();
        return responseMap;
    }

第二个方法

@SuppressWarnings({ "rawtypes", "unused" })
    public static LinkedHashMap sendHttp(Map body, String url) throws Exception {
        CloseableHttpClient httpClient = CommonSendClient
                .acceptsUntrustedCertsHttpClient();
        HttpComponentsClientHttpRequestFactory clientHttpRequestFactory = new HttpComponentsClientHttpRequestFactory(
                httpClient);
        // String workFlowUrl =
        // "https://asset-test.kehujiabj.com:8843/message.mq.front/springtest/test3";
        RestTemplate restTemplate = new RestTemplate(clientHttpRequestFactory);
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        headers.set("Accept-Charset", "UTF-8");
        Object data = JSON.toJSON(body);
        HttpEntity entity = new HttpEntity<Object>(data, headers);
        ResponseEntity<Map> response = restTemplate.exchange(url,
                HttpMethod.POST, entity, Map.class);
        LinkedHashMap responseMap = (LinkedHashMap) response.getBody();
        return responseMap;
    }
