写在开始:一个搬砖程序员的随缘记录
一、SpringBoot项目的搭建
项目搭建传送门:从零开始,SpringBoot项目快速搭建
二、数据库配置
1、新建数据库
在本地mysql数据库新建库,库名:vue_demo,(数据库名字可自行更改,更改完记得在pom.xml中也同步更改)
2、新建用户表
CREATE TABLE `user` (
`id` int(11) NOT NULL,
`username` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`password` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
三、SpringBoot项目的配置
项目结构
