java备份还原mysql数据库(源码经过本人亲自测试通过)

为了mysql的备份与还原我上网找了好长时间愣是没有找到全部通过的，充分说明了先在网上很多转载源码的人 光转载也不看看能不能通过测试。

今天上午终于找到了能够通过测试的源码  先在公布出来希望大家多多点评。 

 

package test1;

import java.io.BufferedReader;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

public class TestMysql {

 

 public static void main(String[] args) {

  System.out.println("开始备份...");

  backup();

  System.out.println("备份成功...");

  

  System.out.println("开始还原...");

  load1();

  System.out.println("还原成功...");

 }

 

 public static void backup() {

  try {

   Runtime rt = Runtime.getRuntime();

   // 调用 调用mysql的安装目录的命令

   Process child = rt

     .exec("C://Program Files//MySQL//MySQL Server 5.1//bin//mysqldump -h localhost -uroot -proot dlgs_test");

   // 设置导出编码为utf-8。这里必须是utf-8

   // 把进程执行中的控制台输出信息写入.sql文件，即生成了备份文件。注：如果不对控制台信息进行读出，则会导致进程堵塞无法运行

   InputStream in = child.getInputStream();// 控制台的输出信息作为输入流

   InputStreamReader xx = new InputStreamReader(in, "utf-8");

   // 设置输出流编码为utf-8。这里必须是utf-8，否则从流中读入的是乱码

   String inStr;

   StringBuffer sb = new StringBuffer("");

   String outStr;

   // 组合控制台输出信息字符串

   BufferedReader br = new BufferedReader(xx);

   while ((inStr = br.readLine()) != null) {

    sb.append(inStr + "rn");

   }

   outStr = sb.toString();

   // 要用来做导入用的sql目标文件：

   FileOutputStream fout = new FileOutputStream(

     "c:/test.sql");

   OutputStreamWriter writer = new OutputStreamWriter(fout, "utf-8");

   writer.write(outStr);

   writer.flush();

   in.close();

   xx.close();

   br.close();

   System.out.println("");

  } catch (Exception e) {

   e.printStackTrace();

  }
