尝试使用 Java 在 Windows 7 上创建文件时出现以下异常。路径的示例是“C: /g-ecx/images-amazon/com/images/G/01/gno/images/orangeBlue/navPackedSprites-US-22.V183711641 .png”。但是，如果我在路径中硬编码，它确实可以工作。我已经敲了两个小时头了，谁能帮忙。

mkdir 失败但没有通过异常，创建文件抛出异常。

    StringBuilder path = new StringBuilder();

    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) {

    if (isNew) {
        try {
            ImageIO.write(image, "jpg", file);

            // TODO Auto-generated catch block

尝试使用

boolean mkdir = file.mkdirs();

代替

boolean mkdir = file.mkdir();

如果需要， mkdirs()创建整个父路径/目录：
