不同数据源之间的数据同步jdbc解决方案

最近项目中用到的数据要从一个数据源获取存进另一个数据源，简单的jdbc解决方案。

package com.sh.ideal.test.syns;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;

        Class.forName("oracle.jdbc.driver.OracleDriver");    //实例化oracle数据库驱动程序(建立中间件)
        String url = "jdbc:oracle:thin:@192.168.1.99:9083:PBD";    //@localhost为服务器名，sjzwish为数据库实例名
        conn = DriverManager.getConnection(url, "pbd", "pbd");    //连接数据库，a代表帐户,a代表密码
        stmt = conn.createStatement();    //提交sql语句,创建一个Statement对象来将SQL语句发送到数据库

        String url1 = "jdbc:oracle:thin:@192.168.1.99:9083:PBD";    //@localhost为服务器名，sjzwish为数据库实例名

            stmt1.execute(insertsql);

        }

        //1代表当前记录的第一个字段的值，可以写成字段名。
        //2代表当前记录的第二个字段的值，可以写成字段名。

        //添加数据用executeUpdate
        //stmt.executeUpdate("insert into ss values(7,'张学友')");

        //修改数据用executeUpdate

        //删除 数据用executeUpdate

        }
