如何使用Java获取MariaDB连接？

Question

I worked on mysql server and connected my java applications successfully. And now I changed to MariaDB. How to connect with MariaDB server using java? How this should be changed?

public class DBConnection {

private Connection connection;
private static DBConnection dBConnection;

public DBConnection() throws ClassNotFoundException, SQLException {
    Class.forName("com.mysql.jdbc.Driver");
    connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/db", "root", "mysql");
}

public static DBConnection getDBConnection() throws ClassNotFoundException, SQLException {
    if (dBConnection == null) {
        dBConnection = new DBConnection();
    }
    return dBConnection;
}

public Connection getConnection() {
    return connection;
}

}

Answer 1

Minor changes for MariaDB are as follows: Use the MariaDB Connector/J with the following Driver class:

org.mariadb.jdbc.Driver

For DB Connection use the following structure:

jdbc:(mysql|mariadb)://host:port/[database]

Therefore, your code as above would only require the change for

Class.forName("org.mariadb.jdbc.Driver");

and the rest would work well since MySQL and MariaDB clients are compatible.After all, MariaDB is an enhanced, drop-in replacement for MySQL.

More information about connecting to MariaDB using the Java Connector can be accessed from MariaDB Knowledge Base (MariaDB Connector/J
