创建springboot工程，引入对应的起步依赖(web、mybatis、mysql驱动、lombok)

创建完载入 Maven 项目

文件树

准备 Mapper、Service、Controller 等基础结构

Mapper（数据访问层）：首先创建Mapper接口和对应的XML文件或者注解配置，用于定义数据访问的方法和SQL语句
Service（业务逻辑层）：接着创建Service接口，定义业务逻辑的方法，然后创建其实现类，实现接口中定义的方法，并处理业务逻辑
Controller（表示层）：最后创建Controller类，处理请求和响应，并调用Service层的方法完成业务逻辑

Mapper

DeptMapper.java

package com.futao.tliasspringbootweb.mapper;import org.apache.ibatis.annotations.Mapper;/*** 部门管理*/
@Mapper
public interface DeptMapper {
}

EmpMapper.java

package com.futao.tliasspringbootweb.mapper;import org.apache.ibatis.annotations.Mapper;/*** 员工管理*/
@Mapper
public interface EmpMapper {
}

Service

DeptService.java

package com.futao.tliasspringbootweb.service;/*** 部门管理*/
public interface DeptService {
}

EmpService.java

package com.futao.tliasspringbootweb.service;/*** 员工管理*/
public interface EmpService {
}

impl/DeptServiceImpl.java

package com.futao.tliasspringbootweb.service.impl;import com.futao.tliasspringbootweb.service.DeptService;
import org.springframework.stereotype.Service;@Service
public class DeptServiceImpl implements DeptService {
}

impl/EmpServiceImpl.java

package com.futao.tliasspringbootweb.service.impl;import com.futao.tliasspringbootweb.service.EmpService;
import org.springframework.stereotype.Service;@Service
public class EmpServiceImpl implements EmpService {
}

Controller

DeptController.java

package com.futao.tliasspringbootweb.controller;import org.springframework.web.bind.annotation.RestController;/*** 部门管理Controller*/
@RestController
public class DeptController {
}

EmpController.java

package com.futao.tliasspringbootweb.controller;import org.springframework.web.bind.annotation.RestController;/*** 员工管理Controller*/
@RestController
public class EmpController {
}

pojo封装类

Dept.java

package com.futao.tliasspringbootweb.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.time.LocalDateTime;/*** 部门实体类*/
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Dept {private Integer id; //IDprivate String name; //部门名称private LocalDateTime createTime; //创建时间private LocalDateTime updateTime; //修改时间
}

Emp.java

package com.futao.tliasspringbootweb.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.time.LocalDate;
import java.time.LocalDateTime;/*** 员工实体类*/
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Emp {private Integer id; //IDprivate String username; //用户名private String password; //密码private String name; //姓名private Short gender; //性别 , 1 男, 2 女private String image; //图像urlprivate Short job; //职位 , 1 班主任 , 2 讲师 , 3 学工主管 , 4 教研主管 , 5 咨询师private LocalDate entrydate; //入职日期private Integer deptId; //部门IDprivate LocalDateTime createTime; //创建时间private LocalDateTime updateTime; //修改时间
}

接口统一响应结果封装类
Result.java

package com.futao.tliasspringbootweb.pojo;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);}
}// { code: , msg: , data:  }
