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)
) ENGINEInnoDB DEFAULT CHARSETutf8mb4 COLLATEutf8mb4_unicode_ci;三、SpringBoot项目的配置
