本文实例讲述了java基于JDBC连接Oracle 11g Release2的方法。分享给大家供大家参考。具体如下：
Oracle 11g Release 2 的 JDBC 连接似乎有所不同 ，如果你收到下面的异常：
Listener refused the connection with the following error:ORA-12505, TNS:listener does not currently know of SID given in connect descriptor.
那么你必须用下面的连接方式：
/******************************************************** Created on Nov, 2011 Copyright(c) http://vigilance.co.in All Rights Reserved.********************************************************/package com.vigilance.java.sample;import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;/** * @author http://vigilance.co.in */public class ConnectJDBCOracle11g {/** * This class demonstrates the code for connecting Oracle 11g database using JDBC. * @param args*/public static void main(String[] args) { String JDBC_DRIVER = "oracle.jdbc.driver.OracleDriver"; String JDBC_STRING = "jdbc:odbc:thin:@HOSTNAME:PORTNUMBER/SID"; // in case of 11g use '/' instead of : String USER_NAME = "USER_NAME"; String PASSWD = "PASSWORD"; Connection conn = null; ResultSet rs = null; Statement stmt = null; try{ Class.forName(JDBC_DRIVER); conn = DriverManager.getConnection(JDBC_STRING, USER_NAME, PASSWD); stmt = conn.createStatement(); String query = "SELECT * FROM TABLE TBL"; rs = stmt.executeQuery(query); }catch(SQLException sqlEx){ sqlEx.printStackTrace(); } catch (ClassNotFoundException e) { e.printStackTrace(); } finally{ try { if(rs!=null) rs.close(); if(stmt !=null) stmt.close(); if(conn!=null) conn.close(); } catch (SQLException e) { e.printStackTrace(); } }}}希望本文所述对大家的java程序设计有所帮助。
