生成一个用restTemplate.postForObject做xml接口生成文件的代码

好的，我可以帮你生成用restTemplate.postForObject做xml接口生成文件的代码，具体代码如下：

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_XML);

String xmlRequest = "<xml><data>your data here</data></xml>";
ResponseEntity<byte[]> responseEntity = restTemplate.postForEntity(xmlUrl, new HttpEntity<>(xmlRequest, headers), byte[].class);

if (responseEntity.getStatusCode() == HttpStatus.OK) {
    byte[] responseBody = responseEntity.getBody();
    // do something with the response body, such as write to file
}

希望能帮助到你！如果你有其他问题，请继续提问。
