我想在我的项目中添加jdom.jar，我做project->properties->Java Build Path->libraries->add external jar jdom-2.0.5，但是不考虑import。我怎样才能使 jdom.jar 可用。这是我要测试的例子
import java.io.FileWriter;
import java.io.IOException;
import org.jdom.Attribute;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.output.Format;
import org.jdom.output.XMLOutputter;
public class WriteXMLFile {
public static void main(String[] args) {
try {
Element company = new Element("company");
Document doc = new Document(company);
doc.setRootElement(company);
Element staff = new Element("staff");
staff.setAttribute(new Attribute("id", "1"));
staff.addContent(new Element("firstname").setText("yong"));
staff.addContent(new Element("lastname").setText("mook kim"));
staff.addContent(new Element("nickname").setText("mkyong"));
staff.addContent(new Element("salary").setText("199999"));
doc.getRootElement().addContent(staff);
Element staff2 = new Element("staff");
staff2.setAttribute(new Attribute("id", "2"));
staff2.addContent(new Element("firstname").setText("low"));
staff2.addContent(new Element("lastname").setText("yin fong"));
staff2.addContent(new Element("nickname").setText("fong fong"));
staff2.addContent(new Element("salary").setText("188888"));
doc.getRootElement().addContent(staff2);
// new XMLOutputter().output(doc, System.out);
XMLOutputter xmlOutput = new XMLOutputter();
// display nice nice
xmlOutput.setFormat(Format.getPrettyFormat());
xmlOutput.output(doc, new FileWriter("c:\\file.xml"));
System.out.println("File Saved!");
} catch (IOException io) {
System.out.println(io.getMessage());
}
}
}
