Is it possible to send XML POST requests with spring, eg RestTemplate?

我想将以下xml发送到网址 localhost：8080 / xml / availability

</AvailReq>

我还想动态地在每个请求上添加自定义http标头（！）。

Also do I want to add custom http headers on each request dynamically(!).

推荐答案

首先，定义你的 HTTP 标题，如下所示：

First of all, define your HTTP headers, like following:

HttpHeaders headers = new HttpHeaders();
headers.add("header_name", "header_value");

您可以使用此设置任何 HTTP 标头做法。对于众所周知的标头，您可以使用预定义的方法。例如，为了设置 Content-Type 标题：

You can set any HTTP header with this approach. For well known headers you can use pre-defined methods. For example, in order to set Content-Type header:

headers.setContentType(MediaType.APPLICATION_XML);

然后定义 HttpEntity 或 RequestEntity 准备您的请求对象：

Then define a HttpEntity or RequestEntity to prepare your request object:

HttpEntity<String> request = new HttpEntity<String>(body, headers);

如果您以某种方式访问​​ XML 字符串，您可以使用 HttpEntity< String> 。否则，您可以定义与 XML 对应的POJO。最后使用 postFor ...发送请求方法：

If you somehow have access to the XML string, you can use HttpEntity<String>. Otherwise you can define a POJO corresponding to that XML. and finally send the request using postFor... methods:

ResponseEntity<String> response = restTemplate.postForEntity("http://localhost:8080/xml/availability", request, String.class);

这里我 POST 请求到 http：// localhost：8080 / xml / availability 端点并将 HTTP 响应主体转换为字符串。

Here i'm POSTing the request to the http://localhost:8080/xml/availability endpoint and converting the HTTP response body into a String.

注意，在上面的例子中 new HttpEntity< String>（... ）可以使用JDK7及更高版本替换为 new HttpEntity<>（...）。

Note, that in the above examples new HttpEntity<String>(...) can be replaced with new HttpEntity<>(...) using JDK7 and later.
