连接到MySQL数据库

Question

如何从Java连接到MySQL数据库？当数据库位于远程服务器上时，Java在本地机器上运行。

Answer 1

这个例子连接到使用MM JDBC驱动程序为MySQL MySQL数据库：

Connection connection = null; 

try { 
    // Load the JDBC driver 
    String driverName = "com.mysql.jdbc.Driver"; // MySQL MM JDBC driver 
    Class.forName(driverName); 

    // Create a connection to the database 
    String serverName = "localhost"; 
    String mydatabase = "mydatabase"; 
    String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url 
    String username = "username"; 
    String password = "password"; 
    connection = DriverManager.getConnection(url, username, password); 
} catch (ClassNotFoundException e) { 
    // Could not find the database driver 
} catch (SQLException e) { 
    // Could not connect to the database 
} 

您必须MySQL数据库的帐户来运行这个例子。要创建一个帐户，您可以连接到MySQL数据库平台的根上，并运行以下命令：

mysql> GRANT SELECT, INSERT, UPDATE, DELETE PRIVILEGES ON *.* 
     TO username@localhost IDENTIFIED BY 'password' WITH GRANT OPTION;
