java - 从 servlet 读取 xml 文件

Question

我无法从 servlet 正确加载文件 xml: 这就是代码:

       try{

           DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
           DocumentBuilder db = dbf.newDocumentBuilder();
           Document doc = db.parse("db.xml");
       } catch (Exception ex) {
       ex.printStackTrace();
           out.print("File Not Found!");
   }

db.xml 位于classes 文件夹内，其中包含类和java 文件...

您需要使用getResourceAsStream()

    try {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document doc = db.parse(getClass().getResourceAsStream("db.xml"));
    } catch (Exception ex) {
        ex.printStackTrace();
        out.print("File Not Found!");
    }
