Myeclipse中连接Oracle的经典代码

 package cn.edu.bit.test;
import java.sql.*;
public class Jdbc {
 public static void main(String[] args)
 {
     try{ 
      Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
     System.out.println("注册成功");    
     String URL = "jdbc:oracle:thin:localhost:1521:orcl";
      String user = "username";  //连接数据库的用户名
      String password = "password";//连接数据库的密码
      Connection conn = DriverManager.getConnection(URL, user, password); 
     System.out.println("连接成功"); 
      Statement st;
       st = conn.createStatement(); 
     ResultSet rs; 
       rs = st.executeQuery("select * from scott.project"); 
    while(rs.next()){ 
       System.out.println(rs.getString("time")); 
     } 
       }catch(Exception e)
     {     e.printStackTrace();    
    
     System.out.println("连接失败");    
   } 
      } 
}
