如何删除 java 中的文件路径编码 %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 space 它在空白 spaces 中用 '%20' 编码。请帮我解决这个问题。

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：

javax.xml.transform.TransformerException: java.io.FileNotFoundException: F:\Backup%20Files\testng2.xml (The system cannot find the path specified)

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");
