尝试创建一个文件来保存图像Java

Question

尝试使用 Java 在 Windows 7 上创建文件时出现以下异常。路径示例为“C:/g-ecx/images-amazon/com/images/G/01/gno/images/orangeBlue/navPackedSprites-US-22.V183711641.png”。如果我在路径中进行硬编码，它确实可以工作。我的头已经敲了两个小时了，谁能帮帮我？

mkdir 失败但没有抛出异常，create file 会抛出异常。

public void processImage(BufferedImage image, URL url) {

    StringBuilder path = new StringBuilder();
    path.append("C:/Users/will/Documents/");
    path.append(url.getHost().replace('.', '/'));
    path.append(url.getFile());
    path.replace(path.lastIndexOf("."), path.length(), ".txt");

    File file = new File(path.toString());

    boolean mkdir = file.mkdir();

    boolean isNew = false;
    try {
        isNew = file.createNewFile();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    /*
     * only create the file if it doesn't exist
     */
    if (isNew) {
        try {
            ImageIO.write(image, "jpg", file);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

尝试使用

boolean mkdir = file.mkdirs();

boolean mkdir = file.mkdir();

mkdirs如果需要， () 创建整个父路径/目录：
