jdbc链接oracle数据库

 

用jdbc链接oracle数据库，需要添加ojdbc.jar包。下面是例子：

 

package com.blade.conn;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class JDBCConnect {
    public static void main (String args[]){
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
            String url="jdbc:oracle:thin:@127.0.0.1:1521:ORCL"; //oracle地址
            String user="blade";
            String password="mirage";
            Connection connection = null;
            try {
                connection= DriverManager.getConnection(url,user,password);
System.out.println("链接成功!");
            } catch (SQLException e) {
                e.printStackTrace();
            }
        } catch (InstantiationException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}
