1.串連代碼

package Util;import java.sql.Connection;import java.sql.DriverManager;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.SQLException;public class DBUtil {    public  static void main  (String args[]){        try {            Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();        } catch (InstantiationException | IllegalAccessException | ClassNotFoundException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        String user = "system";        String password = "密碼";        String url = "jdbc:oracle:thin:@localhost:1521:orcl";        Connection connection = null;        try {                         connection = DriverManager.getConnection(url,user,password);             System.out.println("串連成功");        } catch (SQLException e) {                        System.out.println("串連失敗");            e.printStackTrace();        }                    }    public static void close(Connection connection ) {        try {            if (connection != null) {                connection.close();            }                    } catch (SQLException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    public static void close(PreparedStatement preparedStatement ) {        try {            if (preparedStatement != null) {                preparedStatement.close();            }                    } catch (SQLException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    public static void close(ResultSet resultSet ) {        try {            if (resultSet != null) {                resultSet.close();            }                    } catch (SQLException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    }

2.載入驅動

bulid path->Add External JARs 找到Oracle安裝路徑下的app\Administrator\product\11.2.0\dbhome_1\jdbc\lib\ojbc6_g.jar

 

 

3.在WEB-INT 下lib 複製一個ojbc6_g.jar
