j2EE 利用Quartz任务调度 进行 mysql 数据库自动备份

我们的网站，每次数据库备份都得手动备份，有的时候还会忘记，没出问题还好，要是有问题那就麻烦啦，所以干脆自己写个备份程序吧

使用的quartz的任务调度功能，当然也顺便把它整到spring里面去了，把源码拿来与大家分享：

1. DataBackupImp.java

package cn.hunqiu.data;

import java.io.IOException;
import java.util.Date;

public class DataBackupImp
{
private StringBuffer copyString = new StringBuffer("mysqldump ");//利用mysql的mysqldump 工具，前提是你要吧mysql 的bin目录加入你的系统path
private String lastStr = null;
private String user = "-u****";//***为用户名
private String pwd = "-p***";//***为密码
private String db = "****";//要备份的数据库
private String path = System.getProperty("testhunqiu.root");//你的网站程序的映射地址
private String sqlFileName = null;
@SuppressWarnings("deprecation")
public DataBackupImp()
{
copyString.append(user).append(" ").append(pwd).append(" ").append(db).append(" >");
sqlFileName = path + "WEB-INF\\datacopy\\"+db +"_"+new Date().toLocaleString().replaceAll(":","-")+".sql";
lastStr = copyString + sqlFileName;
}
@SuppressWarnings("deprecation")
public DataBackupImp(String user,String pwd,String db)
{
copyString.append(user).append(" ").append(pwd).append(" ").append(db).append(" >");
sqlFileName = path + "WEB-INF\\datacopy\\"+db +"_"+new Date().toLocaleString().replaceAll(":","-")+".sql";
lastStr = copyString + sqlFileName;
}
@SuppressWarnings("deprecation")
public void dataCopy() throws IOException
{
String temp = ("cmd /c "+lastStr).replaceAll("//","\"\\\\\"").replaceAll("\\\\","\"\\\\\"");//把\换成windows的地址分隔符/
temp=temp.replaceFirst("\"","");
Runtime.getRuntime().exec(temp);
System.out.println("已经完成计算 数据库文件备份----------");
System.out.println("文件路径："+sqlFileName+" 备份时间"+new Date().toLocaleString());
}
}
