SpringCloud: RestTemplate 带header发送post请求

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        headers.set("Accept", "application/json");
        headers.set("Connection", "keep-alive");
        //自定义的header 需要使用add方法！！！ 因HttpHeaders 是MultiValueMap类型的
        headers.add("Authorization", "token");

        RequestInfo requestInfo = new RequestInfo();
        requestInfo.setUsername("admin");
        requestInfo.setPassword("chopin");
        
        HttpEntity httpEntity = new HttpEntity<>(requestInfo, headers);

        RestTemplate r = new RestTemplate();
        String result = r.postForObject("http://localhost:8097/hiHeader", httpEntity, String.class);

        System.out.println(result);
