JDBC连接MYSQL的示例代码

这个代码是从mysql的jdbc的doc里摘下来的：

import java.sql.*;

public class TestMySqlConnection {
    public static void main(String[] args){
        try {
            Class.forName("com.mysql.jdbc.Driver").newInstance();
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        Connection conn = null;
        try {
            conn =
               DriverManager.getConnection("jdbc:mysql://localhost/test?" +
                                           "user=monty&password=greatsqldb");

        } catch (SQLException ex) {
            System.out.println("SQLException: " + ex.getMessage());
            System.out.println("SQLState: " + ex.getSQLState());
            System.out.println("VendorError: " + ex.getErrorCode());
        }
    } 
    
}
