How to restore a MySQL database backup using Java

Question

I was able to create a backup of my current mysql database as .SQL file using the mysqldump.exe with the help of the following java code. <

Answer 1

You should try DbUnit for backup and restore of database.Here is the demo code for that:

    try {
        Class.forName(DBDRIVER);
        Connection jdbcConnection = DriverManager.getConnection(DBURL, DBUSERNAME, DBPASSWORD);
        IDatabaseConnection connection = new DatabaseConnection(jdbcConnection);
        connection.getConfig().setProperty(DatabaseConfig.PROPERTY_DATATYPE_FACTORY,
                    new MySqlDataTypeFactory());

         //////// Database backup
        ITableFilter filter = new DatabaseSequenceFilter(connection);
        IDataSet dataset = new FilteredDataSet(filter, connection.createDataSet());

        ExcludeTableFilter excludeFilter = new ExcludeTableFilter();
        excludeFilter.excludeTable("DATABASECHANGELOG*");
        IDataSet excludedataset = new FilteredDataSet(excludeFilter, dataset);
        FlatXmlDataSet.write(excludedataset, new FileOutputStream(backupfilename));

        System.out.println("\n Complete backup successful.");
         //////// Database backup


         //////// Database restore
        IDataSetProducer producer = new FlatXmlProducer(new InputSource(restoreFileName));
        IDataSet dataSet = new StreamingDataSet(producer);

        TransactionOperation operation = new TransactionOperation(DatabaseOperation.INSERT);
        operation.execute(connection, dataSet);
         //////// Database restore
    } catch (DatabaseUnitException e) {
        e.printStackTrace();
        flag = false;
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (SQLException e) {
        e.printStackTrace();
    }

public static boolean restoreDB(String dbName, String dbUserName, String dbPassword, String source) {  
String[] executeCmd = new String[]{"mysql", "--user=" + dbUserName, "--password=" + dbPassword, dbName,"-e", " source "+source};  
Process runtimeProcess;  
try {  
runtimeProcess = Runtime.getRuntime().exec(executeCmd);  
int processComplete = runtimeProcess.waitFor();  
if (processComplete == 0) {  
    System.out.println("Backup restored successfully");  
    return true;  
}  
} else {  
     System.out.println("Could not restore the backup");  
       }  
        } catch (Exception ex) {  
            ex.printStackTrace();  
        }  
        return false;  
}
