篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了福利贴——爬取美女图片的Java爬虫小程序代码相关的知识,希望对你有一定的参考价值。

自己做的一个Java爬虫小程序

废话不多说,先上图。

文件夹命名是用标签缩写,如果大家看得不顺眼可以等下载完成后手动改一下,比如像有强迫症的我一样。。。

这是挂了一个晚上下载的总大小,不过还有很多因为一些问题没有遍历下载到,而且会产生很多空文件,最下面我附带了一个递归删除空文件夹的小程序代码。

接下来是文件夹内部~

图片存放位置默认为d:\picture,可在程序中更改,main函数的开头就是,有注释。爬取的网站为http://www.mmonly.cc/,大家有更好的资源网站可以私我。

最后就是代码啦。代码挺长的,复制拉取的童鞋们辛苦一下啦。

    }

最后这是一个清理空文件夹的小程序。

ClearEmptyDirs.java

import java.io.File;

public class ClearEmptyDirs
{
    static int i = 0;

    public static void main( String[] args )
    {
        // 文件夹清理的开始位置,默认为d:\pictures
        String dir_str = "d:\\pictures";
        File dir = new File( dir_str );
        clear( dir );
        System.out.println( "清理完毕。" );
        System.out.println( "共删除了" + i + "个空文件夹" );
    }

    public static void clear( File dir )
    {
        File[] dir2 = dir.listFiles();
        for( int i = 0; i < dir2.length; i++ )
        {
            if( dir2[i].isDirectory() )
            {
                clear( dir2[i] );
            }
        }
        if( dir.isDirectory() && dir.delete() )
            i++;
        System.out.println( dir + "删除成功" );

    }

}
