SpringBoot封装增删改查接口

封装了一个科室管理的增删改查接口：

科室列表、科室详情、添加科室、修改科室、删除科室

service层：

package com.yutangzongcai.demo.service;

import com.alibaba.fastjson.JSONObject;
import com.yutangzongcai.demo.entity.DepartmentEntity;
import com.yutangzongcai.demo.mapper.DepartmentMapper;
import com.yutangzongcai.demo.tool.Res;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("admin-api/department")
public class DepartmentService {

    @Autowired
    private DepartmentMapper departmentMapper;

    @PostMapping("list")
    public JSONObject list(@Validated(value = {DepartmentEntity.List.class}) @RequestBody DepartmentEntity departmentEntity) {
        return Res.list(departmentMapper.count(departmentEntity), departmentMapper.list(departmentEntity));
    }

    @PostMapping("detail")
    @Transactional(rollbackFor = Exception.class)
    public JSONObject detail(@Validated(value = {DepartmentEntity.Detail.class}) @RequestBody DepartmentEntity departmentEntity) {
        return Res.detail(departmentMapper.detail(departmentEntity.getId()));
    }

    @RequestMapping("create")
    @Transactional(rollbackFor = Exception.class)
    public JSONObject create(@Validated(value = {DepartmentEntity.Create.class}) @RequestBody DepartmentEntity departmentEntity) {
        return Res.row(departmentMapper.create(departmentEntity), "添加");
    }

    @PostMapping("update")
    @Transactional(rollbackFor = Exception.class)
    public JSONObject update(@Validated(value = {DepartmentEntity.Update.class}) @RequestBody DepartmentEntity departmentEntity) {
        return Res.row(departmentMapper.update(departmentEntity), "修改");
    }

    @PostMapping("delete")
    @Transactional(rollbackFor = Exception.class)
    public JSONObject delete(@Validated(value = {DepartmentEntity.Detail.class}) @RequestBody DepartmentEntity departmentEntity) {
        return Res.row(departmentMapper.delete(departmentEntity.getId()), "删除");
    }

}

dto层、entity层、mapper层、provider层可根据需求自行定义
