首先users.xml在src下
XmlUtils.java
----------------------------------------------------------------------
package cn.itcast.Utils;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;
public class XmlUtils {
private static String filePath;
static {
filePath=XmlUtils.class.getClassLoader().getResource("users.xml").getPath();
}
public static Document getDocument() throws Exception, DocumentException{
SAXReader reader =new SAXReader();
Document document=reader.read(new File(filePath));
return document;
}
public static void write2Xml(Document document) throws IOException, IOException {
org.dom4j.io.OutputFormat format=org.dom4j.io.OutputFormat.createPrettyPrint();
format.setEncoding("UTF-8");
XMLWriter writer=new XMLWriter(new FileOutputStream(filePath),format);
writer.write(document);
writer.close();
}
}
报错内容如下：

------解决方案--------------------
应该是路径有问题。MyEclipse%208.5这个是什么。。。
