我在正在编写的Java应用程序中使用JAXB。我已经成功地将OCI模式编译为类，并且能够将AuthenticationRequest类型编组为XML（在OCIMessage内部），将其发送过来并获得响应。但是，当我尝试将响应编组为OCIMessage时，它会静默失败。这是我的测试课的内容：
package com.some.domain.ignore;
import java.io.IOException;
import java.io.OutputStream;
import java.net.Socket;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBElement;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;
import javax.xml.bind.helpers.DefaultValidationEventHandler;
import javax.xml.stream.FactoryConfigurationError;
import javax.xml.stream.XMLStreamException;
import javax.xml.transform.stream.StreamSource;
import com.some.domain.oci.OCIMessage;
import com.some.domain.oci.ObjectFactory;
import com.some.domain.schema.AuthenticationRequest;
import com.some.domain.schema.AuthenticationResponse;
public class JavaTest {
private final static String HOST = "some.host.com";
private final static int PORT = 2208;
private final static String USER = "SOME_USER";
private final static String SESSION = Long.toString(System.currentTimeMillis());
private static Socket sock;
private static OutputStream out;
private static Marshaller marshaller;
private static Unmarshaller unmarshaller;
private static JAXBContext context;
private static ObjectFactory factory;
public static void main(String[] args) {
try {
runIt();
} catch (Exception e) {
e.printStackTrace();
}
}
private static void runIt() throws XMLStreamException, FactoryConfigurationError, IOException, JAXBException {
sock = new Socket(HOST, PORT);
out = sock.getOutputStream();
AuthenticationRequest request = new AuthenticationRequest();
request.setUserId(USER);
factory = new ObjectFactory();
OCIMessage message = new OCIMessage();
message.setSessionId(SESSION);
message.setProtocol("OCI");
message.getCommand().add(request);
JAXBElement<OCIMessage> element = factory.createBroadsoftDocument(message);
context = JAXBContext.newInstance(ObjectFactory.class);
marshaller = context.createMarshaller();
unmarshaller = context.createUnmarshaller();
marshaller.marshal(element, out);
unmarshaller.setEventHandler(new DefaultValidationEventHandler());
StreamSource s = new StreamSource(sock.getInputStream());
JAXBElement<OCIMessage> doc = unmarshaller.unmarshal(s, OCIMessage.class);
OCIMessage response = doc.getValue();
}
}
实际的XML响应是这样的：
<BroadsoftDocument protocol="OCI" xmlns="C" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<sessionId xmlns="">1329428955041</sessionId>
<command echo="" xsi:type="AuthenticationResponse" xmlns="">
<userId>SOME_USER</userId>
<nonce>1329428959587</nonce>
<passwordAlgorithm>MD5</passwordAlgorithm></command>
</BroadsoftDocument>
解组尝试失败，没有任何错误，这是毫无帮助的。好像JAXB解组代码中的某些东西吞没了该异常，即使我明确指定了一个解组ValidationEventHandler。
有什么想法为什么会这样？如果需要，我可以提供更多代码或信息。
为了进一步参考，这是OCIMessage类：

最佳答案
看起来像是映射错误：响应XML文档包含sessionId元素，并且尚未为其准备AuthenticationResponse类型的映射。如果您发布课程（包括映射注释），我们可以为您提供更多帮助。
