基于springboot3基本使用knife4j-openapi3-jakarta-spring-boot-starter

1.创建springboot项目

1.1准备数据库数据

# 创建数据库
create database if not exists student;
use student;

create table student(
    id int auto_increment primary key ,
    name varchar(20) comment '姓名',
    account varchar(10) comment '账号',
    password varchar(20) comment '密码',
    phone varchar(11) comment '联系方式',
    age int comment '年龄',
    gender varchar(1) comment '性别',
    stu_class varchar(10) comment '班级',
    id_deleted int default 0 comment '是否删除'
)comment '学生信息表';

1.2创建maven项目并导入需要的坐标
