根据过往的文章可以知道目前我已经学习完了前端、后端、数据库的基础知识,接下来通过一个基于SpringBoot工程开发的web项目案例。
前端工程、后端工程、数据库MySQL
-- 部门管理
create table dept
(
id int unsigned primary key auto_increment comment '主键ID',
name varchar(10) not null unique comment '部门名称',
create_time datetime not null comment '创建时间',
update_time datetime not null comment '修改时间'
) comment '部门表';
insert into dept (id, name, create_time, update_time)
values (1, '学工部', now(), now()),
(2, '教研部', now(), now()),
(3, '咨询部', now(), now()),
(4, '就业部', now(), now()),
(5, '人事部', now(), now());
-- 员工管理(带约束)
create table emp
(
id int unsigned primary key auto_increment comment 'ID',
username varchar(20) not null unique comment '用户名',
password varchar(32) default '123456' comment '密码',
name varchar(10) not null comment '姓名',
gender tinyint unsigned not null comment '性别, 说明: 1 男, 2 女',
image varchar(300) comment '图像',
job tinyint unsigned comment '职位, 说明: 1 班主任,2 讲师, 3 学工主管, 4 教研主管, 5 咨询师',
entrydate date comment '入职时间',
dept_id int unsigned comment '部门ID',
create_time datetime not null comment '创建时间',
update_time datetime not null comment '修改时间'
) comment '员工表';
INSERT INTO emp
(id, username, password, name, gender, image, job, entrydate, dept_id, create_time, update_time)

本次案例是基于当前最主流的前后端分离模式进行开发的
package com.example.pojo;
// todo 统一结果的封装类Result
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Result {
private Integer code;//响应码,1 代表成功; 0 代表失败
private String msg; //响应信息 描述字符串
private Object data; //返回的数据
//增删改 成功响应
public static Result success() {
return new Result(1, "success", null);
}
//查询 成功响应
public static Result success(Object data) {
return new Result(1, "success", data);
}
//失败响应
public static Result error(String msg) {
return new Result(0, msg, null);
}
}
