我的需求是：
数据库1使用dao1，
数据库2使用dao2，
数据库1查询出来 的数据 处理后需要 立即插入到 数据库2。
就是一个数据迁移的工具。不打算使用IOC容器。
我在尝试new2个NutDao时出现报错。

    public static void main(String[] args) {
        final SimpleDataSource ds1 = createDataSources("jdbc:mysql://192.168.0.19:3306/db1?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull"
                , "root", "root");
        final SimpleDataSource ds2 = createDataSources("jdbc:mysql://192.168.0.19:3306/db2?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull\n"
                , "root", "root");

        Dao dao1 = new NutDao(ds1);
        Dao dao2 = new NutDao(ds2);
    }

    public static SimpleDataSource createDataSources(String url,String user,String pwd){
        SimpleDataSource dataSource = new SimpleDataSource();
        dataSource.setJdbcUrl(url);
        dataSource.setUsername(user);
        dataSource.setPassword(pwd);
        return dataSource;
    }
