本文實例講述了java基於JDBC銜接Oracle 11g Release2的辦法。分享給年夜家供年夜家參考。詳細以下：

Oracle 11g Release 2 的 JDBC 銜接仿佛有所分歧 ，假如你收到上面的異常：
Listener refused the connection with the following error:ORA-12505, TNS:listener does not currently know of SID given in connect descriptor.
那末你必需用上面的銜接方法：

  // in case of 11g use '/' instead of :

  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();
    }
  }
}
}
