I am calling web service using below method.
我正在使用以下方法调用 Web 服务。
ResponseBean responseBean = getRestTemplate()

Customer bean is a class where which contain all the data which will be used as request body.
客户 bean 是一个类，其中包含将用作请求正文的所有数据。

You can use HttpEntity<T>for your purpose. For example:
您可以HttpEntity<T>根据自己的目的使用。例如：
CustomerBean customerBean = new CustomerBean();
// ...
HttpHeaders headers = new HttpHeaders();
headers.set("headername", "headervalue");
HttpEntity<CustomerBean> request = new HttpEntity<>(customerBean, headers);
ResponseBean response = restTemplate.postForObject(url, request, ResponseBean.class);

Just use the org.springframework.http.HttpHeadersto create your headers and add CustomBean. Sth looks like:
只需使用org.springframework.http.HttpHeaders来创建您的标头并添加 CustomBean。看起来像：
CustomerBean customerBean = new CustomerBean();
HttpHeaders headers = new HttpHeaders();
// can set the content Type
headers.setContentType(MediaType.APPLICATION_JSON);
//Can add token for the authorization
headers.add(HttpHeaders.AUTHORIZATION, "Token");
headers.add("headerINfo", "data");
//put your customBean to header
HttpEntity< CustomerBean > entity = new HttpEntity<>(customBean, headers);
//can post and get the ResponseBean
restTemplate.postForObject(url, entity, ResponseBean.class);
//Or return the ResponseEntity<T>
Hope this help.
希望这有帮助。
