前后端springboot和vue+实现部门的增删改功能记录

前言

大家好 我是歌谣 今天继续带来的是后端java的一个学习记录 首先 我们看一下整体的目录结构

后端目录结构

先写controller层

DeptControll

package com.itheima.controller;


import com.itheima.pojo.Dept;
import com.itheima.pojo.Result;
import com.itheima.service.DeptService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

/**
 * 部门管理Controller
 */
@Slf4j
@RequestMapping("/depts")
@RestController

public class DeptController {
    @Autowired
    private DeptService deptService;
    //查询部门数据
    @GetMapping
    public Result list(){
        //查询全部部门数据
        List<Dept> deptList =deptService.list();
        return Result.success(deptList);
    }
    //删除接口数据
    @DeleteMapping("/{id}")
    public Result delete(@PathVariable Integer id){
        //删除部门数据
        log.info("根据id删除部门",id);
        deptService.delete(id);
        return  Result.success();
    }
    @PostMapping
    public Result add(@RequestBody Dept dept){
        log.info("根据新增部门");
        deptService.add(dept);
        return Result.success();
    }
}

deptSevices

package com.itheima.service;

import com.itheima.mapper.DeptMapper;
import com.itheima.pojo.Dept;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

/**
 * 部门管理
 */
public interface DeptService {

    List<Dept> list();

    void delete(Integer id);

    void add(Dept dept);
}

deptServiceImpl

package com.itheima.service.impl;

import com.itheima.mapper.DeptMapper;
import com.itheima.pojo.Dept;
import com.itheima.service.DeptService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.time.LocalDateTime;
import java.util.List;

@Service
public class DeptServiceImpl implements DeptService {
    @Autowired
    private DeptMapper deptMapper;
    @Override
    public List<Dept> list(){
        return deptMapper.list();
    }

    @Override
    public void delete(Integer id) {
        deptMapper.deleteById(id);
    }

    @Override
    public void add(Dept dept) {
        dept.setCreateTime(LocalDateTime.now());
        dept.setUpdateTime(LocalDateTime.now());
        deptMapper.insert(dept);
    }
}

DeptMapper

package com.itheima.mapper;

import com.itheima.pojo.Dept;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

import java.util.List;

/**
 * 部门管理
 */
@Mapper
public interface DeptMapper {
    @Select("select * from dept")
    List<Dept> list();
    @Delete("delete from dept where id=#{id}")
    void deleteById(Integer id);
    @Insert("insert into dept (name,create_time,update_time) values(#{name},#{createTime},#{updateTime}) ")
    void insert(Dept dept);


}
