import java.io.File;

public class FileTree {

    public static void main(String[] args) {
        printFileTree("D:\\AAAAASSOCWEBDATA",0);
    }

    public static void printFileTree(String driver, int level) {
        File file = new File(driver);
        printByLevel(file.getName(),level);
        if (file.exists()) {
            if(file.isDirectory()){
                File[] children = file.listFiles();
                for (int i = 0; i < children.length; i++) {
                    printFileTree(children[i].getPath(),level+1);
                }
            }
        }
    }

    public static void printByLevel(String name,int level) {
        for (int i = 0; i < level; i++) {
            System.out.print(" ");
        }
        System.out.println("|-〄"+name);
    }

}

结果如下
