java基于JDBC连接Oracle 11g Release2实例分析

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：

public class ConnectJDBCOracle11g {

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。
