Java实现MySQL数据库备份(一)
下班了,利用闲暇时间总结一下如何使用Java语言实现MySQL数据库备份:
- import java.io.BufferedReader;
- import java.io.File;
- import java.io.FileOutputStream;
- import java.io.IOException;
- import java.io.InputStreamReader;
- import java.io.OutputStreamWriter;
- import java.io.PrintWriter;
- /**
- * MySQL数据库备份
- *
- * @author GaoHuanjie
- */
- public class MySQLDatabaseBackup {
- /**
- * Java代码实现MySQL数据库导出
- *
- * @author GaoHuanjie
- * @param hostIP MySQL数据库所在服务器地址IP
- * @param userName 进入数据库所需要的用户名
- * @param password 进入数据库所需要的密码
- * @param savePath 数据库导出文件保存路径
- * @param fileName 数据库导出文件文件名
- * @param databaseName 要导出的数据库名
- * @return 返回true表示导出成功,否则返回false。
