一、程序</td> </tr> </table>
import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.util.Date; import java.text.SimpleDateFormat; import java.util.Properties; public class BackupFile {//将oldPath目录下的所有文件复制到newPath public void copyFolder(String oldPath, String newPath) { try{ (new File(newPath)).mkdirs(); File a = new File(oldPath); String f[] = a.list(); File temp = null; for (int i=0;i< f.length; i++) { if(oldPath.endsWith(File.separator)){ temp = new File(oldPath + f[i]); } else{ temp = new File(oldPath + File.separator + f[i]); } if(temp.isFile()){ FileInputStream input = new FileInputStream(temp); FileOutputStream output =
new FileOutputStream(newPath + "/" + (temp.getName()).toString()); byte[] b = new byte[1024*5]; int len; while((len=input.read(b))!= -1){ output.write(b,0,len); } output.flush(); output.close(); input.close(); } if(temp.isDirectory()){ copyFolder(oldPath + "/" + f[i], newPath + "/" +f[i]); } } } catch(Exception e){ e.printStackTrace(); } }
public String getPro(String name,String path) {
try{
Properties pro = new Properties();
FileInputStream fin = new FileInputStream(path);
pro.load(fin);
return pro.getProperty(name);
}
catch(Exception e){
e.printStackTrace();
return null;
}
}
public static void main(String args[]){
BackupFile bf = new BackupFile();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日");
File f=new File("c:/java/网站备份专用/网站备份日期-"+sdf.format(new Date()));
f.mkdirs();
String folder = bf.getPro("BackupFolders","c:/java/BackupFolders.properties");
System.out.println("取得所有的目录"+folder);
if(folder!=null){
String folders [] = folder.split(",");
for(int i=0; i< folders.length; i++ ){
String roots[] = folders[i].split("%");
bf.copyFolder(roots[0],"c:/java/网站备份专用/"+f.getName()+"/"+roots[1]);
}
}
}
}
二、用属性文件BackupFolders.properties存放要备份的目录，格式如下：
BackupFolders=C:/java/jar%jar,d:/java%java
用逗号隔开各需要备份的目录，用%号隔开要备份的目录与新的存放位置。
三、批处理文件
自动备份.bat
java BackupFile
↑返回目录
