XSD 使用架构问题进行验证
XSD Validation Using Schema Issue
我有一个 xml 文件，例如
<root>
<requestId>1</requestId>
<subRequest>
<id>11</id>
<date>18-02-2015</date>
</subRequest>
<subRequest>
<id>12</id>
<date>19-02-2015</date>
</subRequest>
.
.
</root>
我有一个 XSD 文件，我无法更改该文件中的日期必须采用某种格式。 "subRequest"标签可以有1000个条目。我创建了一个模式验证来检查格式。
所以我的问题出在这 1000 个条目中，如果只有 2 个条目的日期格式不正确，我怎么知道这 2 个条目的 ID。
我在使用 JAXB(unmarshaller) 将此 xml 转换为 bean 时正在检查此内容。我使用了模式验证，并且 validator.getLocalizedMessage() 为对象和节点都提供了 null。我只能看到 lineNumber 和有关问题格式的一般消息。
您可以执行以下操作：
Unmarshaller.Listener
您可以创建一个 Unmarshaller.Listener 来跟踪当前正在解组的 SubRequest。
import javax.xml.bind.Unmarshaller;
public class SubRequestListener extends Unmarshaller.Listener {
private SubRequest subRequest;
@Override
public void beforeUnmarshal(Object target, Object parent) {
if(target.getClass() == SubRequest.class) {
subRequest = (SubRequest) target;
} else {
subRequest = null;
}
}
public SubRequest getSubRequest() {
return subRequest;
}
}
XmlAdapter
然后执行 XmlAdapter 来验证 Date 属性 的内容。在此示例中，我假设您将其存储为 String。如果您将其存储为其他内容（即 Date），则将 XmlAdapter<String, String> 更改为 XmlAdapter<Date, String>。此 XmlAdapter 引用 Unmarshaller.Listener 以获取 SubRequest.
的实例
import java.text.SimpleDateFormat;
import javax.xml.bind.annotation.adapters.XmlAdapter;
public class DateValidator extends XmlAdapter<String, String> {
private SubRequestListener subRequestListener;
public DateValidator() {
this.subRequestListener = new SubRequestListener();
}
public DateValidator(SubRequestListener subRequestListener) {
this.subRequestListener = subRequestListener;
}
@Override
public String marshal(String value) throws Exception {
return value;
}
@Override
public String unmarshal(String value) throws Exception {
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
try {
sdf.applyPattern(value);
} catch(IllegalArgumentException e) {
SubRequest subRequest = subRequestListener.getSubRequest();
System.out.println(subRequest.getId());
}
return value;
}
}
子请求
以下是您如何引用 XmlAdapter。
import javax.xml.bind.annotation.*;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;
@XmlAccessorType(XmlAccessType.FIELD)
public class SubRequest {
private int id;
@XmlJavaTypeAdapter(DateValidator.class)
private String date;
public int getId() {
return id;
}
}
演示
下面是一些关于如何设置的演示代码。
import java.io.File;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Root.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
SubRequestListener unmarshallerListener = new SubRequestListener();
unmarshaller.setListener(unmarshallerListener);
DateValidator dateAdapter = new DateValidator(unmarshallerListener);
unmarshaller.setAdapter(dateAdapter);
File xml = new File("input.xml");
Root root = (Root) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(root, System.out);
}
}
我知道您正在寻找基于 JAXB 的解决方案。
但是，如果您只想找到那个特定的错误，您也可以使用简单的 SAXParser 来快速找到它。也许它可以帮助您首先找到导致错误的原因。
编辑
我在 DefaultHandler 中添加了一个字段，允许您获取引发错误的子请求 ID。
正如我所说，这应该有助于追查错误，它并没有赢得美丽奖。
import java.io.File;
import java.io.IOException;
import javax.xml.XMLConstants;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.xml.sax.helpers.DefaultHandler;
import org.xml.sax.Attributes;
public class RequestParser {
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
Schema schema = null;
try {
String language = XMLConstants.W3C_XML_SCHEMA_NS_URI;
SchemaFactory factory = SchemaFactory.newInstance(language);
schema = factory.newSchema(new File("YOUR_SCHEMA.xsd"));
} catch (Exception e) {
e.printStackTrace();
}
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setSchema(schema);
SAXParser parser = spf.newSAXParser();
parser.parse(new File("YOUR_DOCUMENT.xml"), new DefaultHandler(){
String currentNodeQName = "";
String currentSubrequestId = "";
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
currentNodeQName = qName;
}
public void characters(char[] ch, int start, int length) throws SAXException {
if (currentNodeQName.equals("id")) {
currentSubrequestId = new String(ch, start, length);
}
}
public void warning(SAXParseException e) throws SAXException {
System.out.println("Warning in subrequest with id " + currentSubrequestId);
e.printStackTrace();
}
public void error(SAXParseException e) throws SAXException {
System.out.println("Error in subrequest with id: " + currentSubrequestId);
e.printStackTrace();
}
public void fatalError(SAXParseException e) throws SAXException {
System.out.println("Fatal error in subrequest with id " + currentSubrequestId);
e.printStackTrace();
}
});
}
}
您还可以在这三个异常块处设置断点，这将为您提供有关手头错误的更多信息。

您可以执行以下操作：
Unmarshaller.Listener & ValidationEventHandler
您可以为这个用例创建 Unmarshaller.Listener 和 ValidationEventHandler 的组合。
import javax.xml.bind.*;
public class SubRequestValidator extends Unmarshaller.Listener implements ValidationEventHandler {
private SubRequest subRequest;
@Override
public void beforeUnmarshal(Object target, Object parent) {
if(target.getClass() == SubRequest.class) {
subRequest = (SubRequest) target;
} else {
subRequest = null;
}
}
public SubRequest getSubRequest() {
return subRequest;
}
@Override
public boolean handleEvent(ValidationEvent validationEvent) {
if(subRequest != null) {
System.out.println(subRequest.getId());
System.out.println(validationEvent.getMessage());
}
return validationEvent.getSeverity() != ValidationEvent.FATAL_ERROR;
}
}
那么除了 Schema.
的实例之外，您还可以在 Unmarshaller 上设置两者
SubRequestValidator subRequestValidator = new SubRequestValidator();
unmarshaller.setListener(subRequestValidator);
unmarshaller.setEventHandler(subRequestValidator);
