If you are looking to do an HTTP POST, then you could use the java.net.*APIs in Java SE:
如果您希望执行 HTTP POST，那么您可以使用Java SE 中的java.net.*API：
try {
URL url = new URL(URI);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/xml");
OutputStream os = connection.getOutputStream();
// Write your XML to the OutputStream (JAXB is used in this example)
jaxbContext.createMarshaller().marshal(customer, os);
os.flush();
connection.getResponseCode();
connection.disconnect();
} catch(Exception e) {
throw new RuntimeException(e);
}

XML is a data format. If you talk about requests/responses, you need to know the protocol.
XML 是一种数据格式。如果您谈论请求/响应，则需要了解协议。
My guess is that the protocol you are using is HTTP(S) and you have to do a POST with your XML request, but this is just an educated(?) guess.
我的猜测是您使用的协议是 HTTP(S) 并且您必须对您的 XML 请求进行 POST，但这只是一个受过教育的（？）猜测。

You can use playframework. It is the easiest web framework I have ever used in Java. It is resembles to rails but in java. Give it a try.
您可以使用游戏框架。它是我在 Java 中使用过的最简单的 Web 框架。它类似于rails，但在java中。试一试。
It has a nice and easy to use template engine based on groovy. You can set a request format as described here.
它有一个基于 groovy 的漂亮且易于使用的模板引擎。您可以按照此处所述设置请求格式。
