java 发送Bearer token请求

问题：

在与其他系统进行交互时，客户的服务端需要这样认证，没有办法，只能java 来拼凑了。

java 代码实现如下：

HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.add("Accept", "application/json");
**httpHeaders.add("Authorization", propertyUtils.getDeviceTreeToken());**
String result = getRequest(propertyUtils.getDeviceTreeUrl(), null, httpHeaders);

private String getRequest(String url, MultiValueMap<String, String> params, HttpHeaders headers) throws Exception {
        SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
        requestFactory.setConnectTimeout(10000);// 设置建立连接超时时间
        requestFactory.setReadTimeout(10000);// 设置等待返回超时时间

        RestTemplate client = new RestTemplate(requestFactory);
        HttpMethod method = HttpMethod.GET;
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(params, headers);
        ResponseEntity<String> response = client.exchange(url, method, requestEntity, String.class);
        return response.getBody();
    }

针对于Bearer token改下写法就行：

httpHeaders.add("Authorization", "Bearer " + propertyUtils.getDeviceTreeToken());

这样修改上面的就行了。
