推荐答案

根据您的需要，当然有很多好的解决方案。如果只是配置，你应该看看雅加达 commons-configuration 和 commons-digester 。

There are of course a lot of good solutions based on what you need. If it is just configuration, you should have a look at Jakarta commons-configuration and commons-digester.

你总是可以使用标准的JDK方法获取文档：

You could always use the standard JDK method of getting a document :

import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;

[...]

File file = new File("some/path");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(file);
