  通过Add External JARs..选择D:orclapphrproduct11.2.0dbhome_1owbwflib下的ojdbc14.jar,点击ok。

  2.编写ConnectOracle.java文件

  package com.wuy;

  import java.sql.Connection;

  import java.sql.DriverManager;

  import java.sql.SQLException;

  public class ConnectOracle {

  private Connection con;

  private String user="scott";

  //private String user = "sys as sysdba";

  private String password="18233188050";

  private String className="oracle.jdbc.driver.OracleDriver";

  //private String url="jdbc:oracle:oci@localhost:1158:orcl";这个url可能无效

  private String url = "jdbc:oracle:thin:@hr-PC:1521:orcl";hr-PC和1521很关键,也就是侦听串里有没有这个,在

  D:orclapphrproduct11.2.0dbhome_1NETWORKADMINtnsnames.ora这个文件里有没有,一定要根据tnsnames.ora这个文件来配置url路径,否则会出错!!!

  public ConnectOracle(){

  try{

  Class.forName(className);

  System.out.println("加载数据库驱动成功!");

  }catch(ClassNotFoundException e){

  System.out.println("加载数据库驱动失败!");

  e.printStackTrace();

  }

  }

  /**创建数据库连接*/

  public Connection getCon(){

  try {

  con=DriverManager.getConnection(url,user,password);

  System.out.println("创建数据库连接成功!");

  } catch (SQLException e) {

  System.out.print(con);

  System.out.println("创建数据库连接失败!");

  con=null;

  e.printStackTrace();

  }

  return con;

  }

  public void closed(){

  try{

  if(con!=null){

  con.close();

  }

  }catch(SQLException e){

  System.out.println("关闭con对象失败!");

  e.printStackTrace();

  }

  }

  public static void main(String[] args)

  {

  ConnectOracle c=new ConnectOracle();

  c.getCon();

  c.closed();

  }

  }

  3.运行结果:
