开发环境的准备 新建lib目录把驱动文件放进去设置lib目录为库目录 准备工具包 DbHelper，数据库操作工具包配置文件，让数据库的连接更加动态 编写DbHelper中的内容 加载驱动 获取连接对象 测试代码 测试结果 释放资源 三种资源需要释放： 连接对象执行者结果集 释放资源
解决vue项目报错 POST http://127.0.0.1:3000/login net::ERR_CONNECTION_RESET 通过报错可得知，发送post请求时，服务器端的接口/login拒绝连接 我的错： 在发送请求时，服务器端连接断开了 因为服务器端报错 throw err; // Rethrow non-MySQL errors 显示错误是,results未定义 检
