从一小时开始，我一直在尝试解决 domparser 的问题。我编写了一个简单的应用程序来加载 xml 文件，修改它们并将更改写回。在我将项目转换为 Maven 项目之前，它一直有效。我不确定这是否是问题所在。我无法理解异常
这是我的 DOM 解析器的代码部分：
import java.io.File;
import java.io.IOException;
import javafx.beans.property.BooleanProperty;
import javafx.beans.property.SimpleBooleanProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import **.***.Notification.*;
public class TomcatVM implements ViewModel{
Document tomcatDoc;
Node shutdownPortNode = null;
Node portNode = null;
private StringProperty port = new SimpleStringProperty();
private StringProperty shutdownPort = new SimpleStringProperty();
private BooleanProperty tomcatService = new SimpleBooleanProperty();
private String fullTomcatPropPath = new String();
private StringProperty path = new SimpleStringProperty();
public void init() {
NotificationCenter.getDefaultNotificationCenter().addObserverForName(Notification.LOAD_NOTIFICATION.toString(), new NotificationObserver() {
@Override
public void receivedNotification(final String arg0, final Object... arg1) {
// TODO Auto-generated method stub
File tomcatXmlFile = new File(getFullTomcatPropPath());
if(tomcatXmlFile != null){
try{
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
System.out.println("got: "+getFullTomcatPropPath());
System.out.println("path: "+tomcatXmlFile.getPath());
tomcatDoc = dBuilder.parse(tomcatXmlFile);
tomcatDoc.getDocumentElement().normalize();
if(tomcatDoc != null){
shutdownPortNode = tomcatDoc.getElementsByTagName("Server").item(0).getAttributes().getNamedItem("port");
portNode = tomcatDoc.getElementsByTagName("Connector").item(0).getAttributes().getNamedItem("port");
// tomcatShutdownPortTextField.setText(shutdownPortNode.getTextContent());
setPort(portNode.getTextContent());
setShutdownPort(shutdownPortNode.getTextContent());
}
}catch(Exception e){
e.printStackTrace();
}
}
}
});
NotificationCenter.getDefaultNotificationCenter().addObserverForName(Notification.SAVE_NOTIFICATION.toString(), new NotificationObserver() {
/*
* write changes from the interface to the doc file for
* the tomcat-xml file and overwrite the old tomcat-xml
*/
@Override
public void receivedNotification(final String arg0, final Object... arg1) {
portNode.setTextContent(getPort().toString());
shutdownPortNode.setTextContent(getShutdownPort().toString());
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer;
try {
transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(tomcatDoc);
StreamResult result = new StreamResult(new File(getFullTomcatPropPath()));
enter code here // ******here is the exception: *******
transformer.transform(source, result);
} catch (TransformerConfigurationException e) {
e.printStackTrace();
} catch (TransformerException e) {
e.printStackTrace();
}
}
});
}
public String getFullTomcatPropPath() {
return fullTomcatPropPath;
}
public void setFullTomcatPropPath(final String fullTomcatPropPath) {
this.fullTomcatPropPath = fullTomcatPropPath;
}
}
这是我得到的例外：

我没有为 dom-parser 添加任何依赖项到我的 pom.xml 中。相同的代码在另一个项目中运行，唯一的区别是，我得到异常的项目是一个 maven 项目。如果我注释掉这一行，我会在另一个保存另一个 xml 文件的类上遇到异常。所以我认为是不是tomcat的问题？有人有想法吗？：/
提前致谢！
