Question

我需要在unix框中将文件从一个位置移动到另一个位置，我使用以下代码执行移动：

s/\s+/ /g;

一旦文件在目的地，我需要做一些额外的处理。我让代码休眠10秒，这样在处理开始之前，移动应该已经完成了。有没有更好的方法来确保在其余代码运行之前移动成功？

How to move directories using jdk7

Moving files from one directory to another with Java NIO

Path sourcePath = Paths.get(infaFileOut);
Path destinationPath = Paths.get(fileOut);
try{
Files.move(sourcePath, destinationPath, StandardCopyOption.REPLACE_EXISTING);
} catch (IOException e) {
    //this is where the error will be thrown if the file did not move properly 
    //(null pointer etc...), you can place code here to run if there is an error
    e.printStackTrace();
}

如果你的额外偏执尝试打印出所有内容：

   Path sourceDir = Paths.get("c:\\source");
    Path destinationDir = Paths.get("c:\\dest");

    try (DirectoryStream<Path> directoryStream = Files.newDirectoryStream(sourceDir)) {
        for (Path path : directoryStream) {
            System.out.println("copying " + path.toString());
            Path d2 = destinationDir.resolve(path.getFileName());
            System.out.println("destination File=" + d2);
            Files.move(path, d2, REPLACE_EXISTING);
        }
    } catch (IOException ex) {
        ex.printStackTrace();
    }
