博客《Java实现MySQL数据库备份(一)》使用I/O流的方式实现了MySQL数据库的备份,这种方法比较繁杂,下面介绍另一种备份MySQL数据库的方法:
- import java.io.File;
- import java.io.IOException;
-
- public class MySQLDatabaseBackup {
-
-
- public static boolean exportDatabaseTool(String hostIP, String userName, String password, String savePath, String fileName, String databaseName) {
- File saveFile = new File(savePath);
- if (!saveFile.exists()) {
- saveFile.mkdirs();
- }
- if (!savePath.endsWith(File.separator)) {
- savePath = savePath + File.separator;
- }
-
- StringBuilder stringBuilder = new StringBuilder();
- stringBuilder.append("mysqldump").append(" --opt").append(" -h").append(hostIP);
- stringBuilder.append(" --user=").append(userName) .append(" --password=").append(password).append(" --lock-all-tables=true");
- stringBuilder.append(" --result-file=").append(savePath + fileName).append(" --default-character-set=utf8 ").append(databaseName);
- try {
- Process process = Runtime.getRuntime().exec(stringBuilder.toString());
- if (process.waitFor() == 0) {
- return true;
- }
- } catch (IOException e) {
- e.printStackTrace();
- } catch (InterruptedException e) {
- e.printStackTrace();
- }
- return false;
- }
-
- public static void main(String[] args) throws InterruptedException {
- if (exportDatabaseTool("172.16.0.127", "root", "123456", "D:/backupDatabase", "2014-10-14.sql", "test")) {
- System.out.println("数据库备份成功!!!");
- } else {
- System.out.println("数据库备份失败!!!");
- }
- }
- }
