JDBC (本机Oracle连接)

本机连接Oracle流程：

首先，查看一下自己的计算机名：

进入Oracle配置文件Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN把host值修改为本机(只需修改host值)

listenter.ora文件：

# listener.ora Network Configuration File: D:\Oracle11g\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
      (SID_LIST =
      (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\Oracle11g\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\Oracle11g\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )



LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 本机名)(PORT = 1521))
    )
  )



ADR_BASE_LISTENER = D:\Oracle11g

tnsnames.ora文件：

# tnsnames.ora Network Configuration File: D:\Oracle11g\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 本机名)(PORT = 1521))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 本机名)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = orcl)
      (SERVICE_NAME = orcl)
    )
  )

(在导入了ojdbc.jar驱动的前提下)

JDBC测试：

package cn.library.hnucm.util;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;


public class DBUtil {

    public static Connection getConnection() {

        //连接Oracle
        String url="jdbc:oracle:thin:@127.0.0.1:1521/orcl";
        String username = "system";
        String password = "Oracle11g";
        String driver="oracle.jdbc.driver.OracleDriver";  
        try {
            Class.forName(driver);
            Connection con= DriverManager.getConnection(url, username, password);
            return con;
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return null;
    }

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Connection con = DBUtil.getConnection();
        System.out.println(con.toString());
    }

}

测试成功：
