jdbc连接不指定数据库初始化的时候会报错

        SimpleDataSource simpleDataSource = new SimpleDataSource();
        simpleDataSource.setJdbcUrl("jdbc:mysql://127.0.0.1:3306");
        simpleDataSource.setUsername("root");
        simpleDataSource.setPassword("123456");
        NutDao nutDao = new NutDao(simpleDataSource);
