java - 文件无法解析，因为 java 找不到

问题描述

我正在尝试解析一个 xml 文件，到目前为止，这就是我所写的。

public class XMLTest {

public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
    File xmlFile = new File("D:\\workspace\\sudoku baby\\sudoku.xml");
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    Document doc = dBuilder.parse(xmlFile);
}

它不断吐出文件未找到异常，就像这样

Exception in thread "main" java.io.FileNotFoundException: D:\workspace\sudoku baby\sudoku.xml (The system cannot find the file specified)

` 我已经确定它是正确的文件路径，并且经过一些测试它可以找到该文件。当我尝试解析它时会发生错误。我不确定这里的问题到底是什么，如果有人可以指出它或提供帮助，那就太好了。

解决方案

请尝试以下代码：

File xmlFile = new File(Paths.get("D:","workspace", "sudoku baby", "sudoku.xml").toString());
