使用java发布xml数据

URL url = new URL("http://example.com/xml");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "application/xml; charset=UTF-8");

// 写入XML数据
Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
Element rootElement = document.createElement("root");
document.appendChild(rootElement);

Element element1 = document.createElement("element1");
element1.setTextContent("value1");
rootElement.appendChild(element1);

Element element2 = document.createElement("element2");
element2.setTextContent("value2");
rootElement.appendChild(element2);

TransformerFactory.newInstance().newTransformer().transform(new DOMSource(document), new StreamResult(connection.getOutputStream()));

// 读取响应
InputStream inputStream;
if (connection.getResponseCode() >= 400) {
    inputStream = connection.getErrorStream();
} else {
    inputStream = connection.getInputStream();
}

// 处理响应的XML数据
