oracle jdbc驱动源代码

可以用JD-GUI反编译jar

看那个jar包ojdbc14.jar?

package com.niit;
import java.sql.*;
public class ConnDB {
public static Connection getConnection(){
Connection conn = null;
String driver = "oracle.jdbc.driver.OracleDriver";
String url = "jdbc:oracle:thin:@localhost:1521:orcl";
String username = "wcy";
String password = "wcy";
try {
//注册驱动
Class.forName(driver);
//构建连接
conn = DriverManager.getConnection(url, username,password);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
return conn;
}

public static void main(String [] args){
if(getConnection()!=null){
System.out.println("连接成功");
}
}
}
