我的JAXB解析器今天突然停止工作。它工作了幾個星期。我收到以下消息。我幾個星期沒有更改這個代碼。想知道這個設置是否好。JAXB問題 - 意外元素
編輯2:請有人可以幫助我!我無法弄清楚這一點。
編輯1: 以下運行相同的代碼我的驗收測試工作正常。我相信這是一個 類加載問題。我在JDK中使用JAXB和StAX。但是,當我部署到jboss 5.1時,出現下面的錯誤。使用1.6.0_26(本地)和1.6.0_30(開發服務器)。仍然困惑於解決方案。
意外元件(URI: 「」,本地: 「lineEquipmentRecord」)。預期 元件是 < {} switchType>,< {} leSwitchId>,< {} nodeAddress>,< {} LEID>,< {} telephoneSuffix>,< {} leFormatCode>,< {} groupIdentifier>,< {} telephoneNpa>,< {} telephoneLine>,< {} telephoneNxx>
這是我的數據編類:
import java.io.InputStream;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.NoSuchElementException;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import javax.xml.bind.ValidationEvent;
import javax.xml.bind.ValidationEventHandler;
import javax.xml.stream.FactoryConfigurationError;
import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamConstants;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamReader;
public class PartialUnmarshaller<T> {
XMLStreamReader reader;
Class<T> clazz;
Unmarshaller unmarshaller;
public PartialUnmarshaller(InputStream stream, Class<T> clazz) throws XMLStreamException, FactoryConfigurationError, JAXBException {
this.clazz = clazz;
this.unmarshaller = JAXBContext.newInstance(clazz).createUnmarshaller();
unmarshaller.setEventHandler(new ValidationEventHandler() {
@Override
public boolean handleEvent(ValidationEvent event) {
System.out.println(event.getMessage());
return true;
}
});
this.reader = XMLInputFactory.newInstance().createXMLStreamReader(stream);
/* ignore headers */
skipElements(XMLStreamConstants.START_DOCUMENT);
/* ignore root element */
reader.nextTag();
/* if there's no tag, ignore root element's end */
skipElements(XMLStreamConstants.END_ELEMENT);
}
public T next() throws XMLStreamException, JAXBException {
if (!hasNext())
throw new NoSuchElementException();
T value = unmarshaller.unmarshal(reader, clazz).getValue();
skipElements(XMLStreamConstants.CHARACTERS, XMLStreamConstants.END_ELEMENT);
return value;
}
public boolean hasNext() throws XMLStreamException {
return reader.hasNext();
}
public void close() throws XMLStreamException {
reader.close();
}
private void skipElements(Integer... elements) throws XMLStreamException {
int eventType = reader.getEventType();
List<Integer> types = new ArrayList<Integer>(Arrays.asList(elements));
while (types.contains(eventType))
eventType = reader.next();
}
}
此類用於如下:
List<MyClass> lenList = new ArrayList<MyClass>();
PartialUnmarshaller<MyClass> pu = new PartialUnmarshaller<MyClass>(
is, MyClass.class);
while (pu.hasNext()) {
lenList.add(pu.next());
}
的XML是解組:
<?xml version="1.0" encoding="UTF-8"?>
<lineEquipment>
<lineEquipmentRecord>
<telephoneNpa>333</telephoneNpa>
<telephoneNxx>333</telephoneNxx>
<telephoneLine>4444</telephoneLine>
<telephoneSuffix>1</telephoneSuffix>
<nodeAddress>xxxx</nodeAddress>
<groupIdentifier>LEN</groupIdentifier>
</lineEquipmentRecord>
<lineEquipmentRecord>
<telephoneNpa>111</telephoneNpa>
<telephoneNxx>111</telephoneNxx>
<telephoneLine>2222</telephoneLine>
<telephoneSuffix>0</telephoneSuffix>
<nodeAddress>xxxx</nodeAddress>
<groupIdentifier>LEN</groupIdentifier>
</lineEquipmentRecord>
</lineEquipment>
最後,這裏是MyClass的:
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
/**
* This class is used as an envelope to hold Martens
* line equipment information.
* @author spgezf
*
*/
@XmlRootElement(name="lineEquipmentRecord")
public class MyClass {
private String telephoneNpa;
private String telephoneNxx;
private String telephoneLine;
private String telephoneSuffix;
private String nodeAddress;
private String groupIdentifier;
public MyClass(){
}
// Getters and Setters.
@XmlElement(name="telephoneNpa")
public String getTelephoneNpa() {
return telephoneNpa;
}
public void setTelephoneNpa(String telephoneNpa) {
this.telephoneNpa = telephoneNpa;
}
@XmlElement(name="telephoneNxx")
public String getTelephoneNxx() {
return telephoneNxx;
}
public void setTelephoneNxx(String telephoneNxx) {
this.telephoneNxx = telephoneNxx;
}
@XmlElement(name="telephoneLine")
public String getTelephoneLine() {
return telephoneLine;
}
public void setTelephoneLine(String telephoneLine) {
this.telephoneLine = telephoneLine;
}
@XmlElement(name="telephoneSuffix")
public String getTelephoneSuffix() {
return telephoneSuffix;
}
public void setTelephoneSuffix(String telephoneSuffix) {
this.telephoneSuffix = telephoneSuffix;
}
@XmlElement(name="nodeAddress")
public String getNodeAddress() {
return nodeAddress;
}
public void setNodeAddress(String nodeAddress) {
this.nodeAddress = nodeAddress;
}
@XmlElement(name="groupIdentifier")
public String getGroupIdentifier() {
return groupIdentifier;
}
public void setGroupIdentifier(String groupIdentifier) {
this.groupIdentifier = groupIdentifier;
}
}
