mysql数据库备份及还原详解编程语言

// 调用 调用mysql的安装目录的命令 Process child = rt.exec("D:/MySQL/bin/mysqldump.exe -h 121.28.144.94 -uroot -psanmi123 gdsite"); // 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 + "/r/n"); 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(); writer.close(); fout.close(); System.out.println("-------------------------"); } catch (Exception e) { e.printStackTrace(); }

数据库还原代码：

public static void restore(String databaseName) { 

 try { 

 Runtime runtime = Runtime.getRuntime(); 

 Process process = runtime 

 .exec("e://MySQL//bin//mysql.exe -hlocalhost -uroot -p123 --default-character-set=utf8 " 

 + databaseName); 

 OutputStream outputStream = process.getOutputStream(); 

 BufferedReader br = new BufferedReader(new InputStreamReader( 

 new FileInputStream("C://test.sql"), "utf-8")); 

 String str = null; 

 StringBuffer sb = new StringBuffer(); 

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

 sb.append(str + "/r/n"); 

 str = sb.toString(); 

 // System.out.println(str); 

 OutputStreamWriter writer = new OutputStreamWriter(outputStream, 

 "utf-8"); 

 writer.write(str); 

 writer.flush(); 

 outputStream.close(); 

 br.close(); 

 writer.close(); 

 } catch (UnsupportedEncodingException e) { 

 e.printStackTrace(); 

 } catch (FileNotFoundException e) { 

 e.printStackTrace(); 

 } catch (IOException e) { 

 e.printStackTrace(); 

 }
