Java 如何从wsdl生成请求和响应类？

我有一个用Maven构建的Spring Boot应用程序。现在，我计划从这个应用程序向SOAP服务发出请求。SOAP服务由WSDL定义。我可以使用此方法发出请求并获得响应：

private String makeSoapRequest(String request, String action) throws IOException {
    URL url = new URL("http://localhost/");
    URLConnection urlConnection = url.openConnection();
    HttpURLConnection httpURLConnection = (HttpURLConnection)urlConnection;


    InputStream is = new ByteArrayInputStream(request.getBytes());
    baos = new ByteArrayOutputStream();

    copy(is, baos);
    is.close();

    byte[] bytes = baos.toByteArray();

    httpURLConnection.setRequestProperty("Content-Length", String.valueOf( bytes.length ) );
    httpURLConnection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
    httpURLConnection.setRequestProperty("SOAPAction", action);
    httpURLConnection.setRequestMethod("POST");
    httpURLConnection.setDoOutput(true);
    httpURLConnection.setDoInput(true);

    OutputStream out = httpURLConnection.getOutputStream();
    out.write(bytes);
    out.close();

    InputStreamReader isr = new InputStreamReader(httpURLConnection.getInputStream());
    BufferedReader in = new BufferedReader(isr);

    String inputLine;
    StringBuilder sb = new StringBuilder();
    while ((inputLine = in.readLine()) != null) {
        ab.append(inputLine);
    }

    return sb.ToString();
}

但是，这里的请求和响应是XML字符串。如何从WSDL生成请求和响应类，以便使用它们发出带有

HttpURLConnection

的请求

使用apachecxf没有帮助，因为我应该使用

HttpURLConnection

。这是消费服务的需求之一

我可以使用JAXB或JAX-WS生成类，但将生成的适当类作为请求体发送给我会导致400个错误请求。

您应该使用代码生成器。您可以在CXF文档中找到有关WSDL2Java的更多信息：
