一个获得jdbc方式Connection的静态方法

本例子源自慕课网jsp,servlet生成报表课程的例子，使用的是mysql数据库

package jdbc;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class JdbcConn {
	private static String url="jdbc:mysql://localhost:3336/testReport";
	private static String username="root";
	private static String password="myoa888";
	
	private static Connection conn;
	private static PreparedStatement ps;
	private static Statement st;
	private static ResultSet rs;
	
	public static Connection getConnection(){
		try {
			Class.forName("com.mysql.jdbc.Driver");
			conn=DriverManager.getConnection(url, username, password);
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}
		return conn;
	}
}
