【解决方案1】:
据我所知,Jax-ws 使用 POST 来接听电话。您必须构建一个 XML 请求以 POST 到您的 URL。像这样的:
POST /ws/hello HTTP/1.1
SOAPAction: ""
Accept: text/xml, multipart/related, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Content-Type: text/xml; charset=utf-8
User-Agent: Java/1.6.0_13
Host: localhost:9999
Connection: keep-alive
Content-Length: 224
<?xml version="1.0" ?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:getHelloWorldAsString xmlns:ns2="http://ws.mkyong.com/">
<arg0>test</arg0>
</ns2:getHelloWorldAsString>
</S:Body>
</S:Envelope>
【解决方案2】:
使用 java.net.Url 和 HttpURLConnection 或 HTTPSURLConnection
看样例
URL url = new URL("http://yourwebservices.soap.wsdl");
HttpURLConnection connectionWS = (HttpURLConnection) ur.openConnection();
//not forget this
connectionWS.setDoOutput(true);
connectionWS.setDoInput(true);
connectionWS.setRequestMethod("POST");
connectionMinervaWS.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
StringBuilder envelopeSoapRequest = new StringBuilder()
//make the xml request
//now you send to service
OutputStreamWriter osw = new OutputStreamWriter( connectionWS.getOutputStream() );
osw.write( envelopeSoapRequest.toString() );
osw.flush();
//now you can take response
BufferedReader wsReader = null;
StringBuilder envelopeSoapResponse = new StringBuilder();
wsReader = new BufferedReader(new InputStreamReader(
connectionWS.getInputStream(), StandardCharsets.UTF_8 ));
String line = wsReader.readLine();
while (line != null) {
envelopeSoapResponse.append( line );
line = wsReader.readLine();
}
