解决使用jaxb读取xml文件报javax.xml.bind.UnmarshalException: 意外的元素 的错误问题。
当使用javax.xml.bind包下的JAXBContext类对xml进行解析时候，在xml源文件的标签中存在命名空间时候，会产生javax.xml.bind.UnmarshalException: 意外的元素 (uri:"urn:swift:xsd:envelope", local:"Envelope")。所需元素为<{}Envelope> 问题。
xml原文文件内容如下：
CITIUS33XXX
CITIUS33XXX
TESTINGSIT00003
pacs.008.001.08
swift.cbprplus.01

使用javax.xml.bind的包下的JAXBContext类的解析代码。
public class TestFileXml {
public static void main(String[] args) {
File file = new File("D:\\学习记录\\JDK\\JavaX\\测试解析XML.xml");
try {
JAXBContext jaxbContext = JAXBContext.newInstance(EnvelopeEntity.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
EnvelopeEntity entity = (EnvelopeEntity) unmarshaller.unmarshal(file);
System.out.println(entity.toString());
} catch (JAXBException e) {
e.printStackTrace();
}
}
}对象xml文件的实体类EnvelopeEntity，在实体类中我们使用javax.xml.bind.annotation包下的注释和xml文件标签进行关联。

}
}*/
public static void main(String[] args) {
File file = new File("D:\\学习记录\\JDK\\JavaX\\测试解析XML.xml");
try {
JAXBContext jaxbContext = JAXBContext.newInstance(EnvelopeEntity.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
SAXSource saxSource = newSAxSource(file);
EnvelopeEntity entity = (EnvelopeEntity) unmarshaller.unmarshal(saxSource);
System.out.println(entity.toString());
} catch (JAXBException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
/**
* 这里主要是忽略xml文件的命名空间
* @param file
* @return
* @throws FileNotFoundException
* @throws ParserConfigurationException
* @throws SAXException
*/
protected static SAXSource newSAxSource(File file) throws FileNotFoundException, ParserConfigurationException, SAXException {
FileReader fileReader = new FileReader(file);
SAXParserFactory saxParserFactory = SAXParserFactory.newDefaultInstance();
saxParserFactory.setNamespaceAware(false);
XMLReader xmlReader = saxParserFactory.newSAXParser().getXMLReader();
SAXSource saxSource = new SAXSource(xmlReader, new InputSource(fileReader));
return saxSource;
}
}
输出结果如下：
EnvelopeEntity{appHdrEntity={frEntity={bicfi='CITIUS33XXX'}, toEntity={bicfi='CITIUS33XXX'}, bizMsgIdr='TESTINGSIT00003', msgDefIdr='pacs.008.001.08', bizSvc='swift.cbprplus.01', creDt='2019-01-11T12:43:41.960+00:00'}, documentEntity={pmtIdEntityList=[{instrId='1-TESTINGSIT00003', endToEndId='1-KK04044506271305', uetr='1-174c245f-2682-4291-ad67-2a41e530cd27'}, {instrId='2-TESTINGSIT00003', endToEndId='2-KK04044506271305', uetr='2-174c245f-2682-4291-ad67-2a41e530cd27'}]}}
总结：
我们可以使用javax.xml.parsers包下的功能类去解决读取xml文件中的命名空间问题。
