在java 最简单连接数据库的方式

public class Test
{
public static void main(String[] args) throws ClassNotFoundException, SQLException
{
//jdbc:mysql://127.0.0.1:3306/jboa?autoReconnect=true

Class.forName("com.mysql.jdbc.Driver");
Connection connection=	DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/jboa?autoReconnect=true", "root", "root");
Statement stm=connection.createStatement();
String sql="SELECT * FROM ac_area";
ResultSet rs=	stm.executeQuery(sql);
while(rs.next())
{
System.out.println(rs.getObject(1));
System.out.println(rs.getObject(2));
System.out.println(rs.getObject(3));
System.out.println(rs.getObject(4));
}
rs.close();
stm.close();
connection.close();

}
}
