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

public class BackupMysql {
/** 访问MySQL服务器所在的url */
private String serverUrl;
/** 访问MySQL数据库的用户名 */
private String username;
/** 访问MySQL数据库的密码 */
private String password;

public String getServerUrl() {
return serverUrl;
}

public void setServerUrl(String serverUrl) {
this.serverUrl = serverUrl;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public BackupMysql(String serverUrl,String username, String password) {
super();
this.serverUrl=serverUrl;
this.username = username;
this.password = password;
}

public String backup(String backupPath, String dbName) throws IOException {

String backupFile = backupPath+ dbName+ new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss").format(new Date()) + ".sql";

String = "mysqldump "+"--host="+serverUrl+" --user=" + username + " --password="+ password + " --opt " + dbName + "> " + backupFile;

java.lang.Runtime.getRuntime().exec("cmd /c " + mysql);

System.out.println("备份成功!");

return backupFile;

}

public void restore(String restoreFile, String dbName) throws Exception {

String mysql = "mysql "+"-h"+serverUrl+" -u" + username + " -p"+ password + " " + dbName + " < " + restoreFile;

System.out.println(mysql);

java.lang.Runtime.getRuntime().exec("cmd /c " + mysql);

System.out.println("还原成功!");
}

/**
* @param args
*/
public static void main(String[] args) {

String serverUrl="127.0.0.1";

String userName = "root";

String pwd = "root";

BackupMysql backup = new BackupMysql(serverUrl,userName, pwd);

try {
backup.restore("d:/nationz2010-12-20-14-16-47.sql", "nationz");
} catch (Exception e) {
e.printStackTrace();
}
}
}
