java - 如何在 java 中删除文件路径编码 %20

Question

我正在尝试使用 java 在特定路径中创建一个 xml 文件。 问题是，如果我给文件路径加上空格，它在空格中用 '%20' 编码。 请帮助我解决这个问题。

我给的文件路径——“F:/Backup Files/testng2.xml”
编码后——“F:/Backup%20Files/testng2.xml”

代码:

 TransformerFactory transformerFactory = TransformerFactory.newInstance();
 Transformer transformer = transformerFactory.newTransformer();
 DOMSource source = new DOMSource(doc);
 StreamResult result = new StreamResult(new File("F:/Backup Files/testng2.xml"));       
 transformer.transform(source, result);
 System.out.println("File saved successfully");

错误:

尝试将 .getAbsolutePath() 添加到您的 File，如下所示:

    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    DOMSource source = new DOMSource(doc);
    StreamResult result = new StreamResult(new File("F:/Backup Files/testng2.xml").getAbsolutePath());        
    transformer.transform(source, result);
    System.out.println("File saved successfully");
