如何借助AI在20分钟内写一个springboot单表的增删改查

1. AI工具介绍

在idea的插件市场里：
在这里插入图片描述

2. 写代码的正确顺序

2.1 编写 Entity 类：

定义与数据库表对应的领域模型类，包括字段、getter 和 setter 方法。
注意：主要确定各个字段的合理性，sql对于的idea上的类型，例如日期Date类，在Java上需要加注解@DateTimeFormat(value = “yyyy-MM-dd”)来固定格式。

package com.goblin.BIbackend.model.entity;import com.alibaba.excel.annotation.format.DateTimeFormat;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import java.io.Serializable;
import java.util.Date;
import lombok.Data;/**** @TableName install_requests*/
@TableName(value ="install_requests")
@Data
public class InstallRequests implements Serializable {/****/@TableId(type = IdType.AUTO)private Long id;/****/private Long userId;/****/@DateTimeFormat(value = "yyyy-MM-dd")private Date requestDate;/****/private String status;/****/private String description;@TableField(exist = false)private static final long serialVersionUID = 1L;
}

2.2 编写 Mapper 接口：

创建与数据库操作相关的接口，使用 MyBatis 或 JPA 等 ORM 框架注解来标识数据库操作。

package com.goblin.BIbackend.mapper;import com.goblin.BIbackend.model.entity.InstallationProgress;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;/**
* @author **
* @description 针对表【installation_progress】的数据库操作Mapper
* @createDate 2024-07-07 00:36:01
* @Entity com.goblin.BIbackend.model.entity.InstallationProgress
*/
public interface InstallationProgressMapper extends BaseMapper<InstallationProgress> {public InstallationProgress select1(Long id);public void insert1(InstallationProgress installationProgress);public void delete1(Long id);public void update1(InstallationProgress installationProgress);
}

2.3 编写 Mapper XML 文件（如果使用 MyBatis）：

在 XML 文件中编写具体的 SQL 语句和结果映射，与 Mapper 接口中的方法相对应。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.goblin.BIbackend.mapper.InstallRequestsMapper"><resultMap id="BaseResultMap" type="com.goblin.BIbackend.model.entity.InstallRequests"><id property="id" column="id" jdbcType="BIGINT"/><result property="userId" column="user_id" jdbcType="BIGINT"/><result property="requestDate" column="request_date" jdbcType="DATE"/><result property="status" column="status" jdbcType="VARCHAR"/><result property="description" column="description" jdbcType="VARCHAR"/></resultMap><sql id="Base_Column_List">id,user_id,request_date,status,description</sql><select id="select1" resultMap="BaseResultMap">SELECT * FROM install_requests where id = #{id}</select><insert id="insert1" parameterType="com.goblin.BIbackend.model.entity.InstallRequests">INSERT INTO install_requests (user_id,request_date,status,description)VALUES (#{userId},#{requestDate},#{status},#{description})</insert><delete id="delete1" parameterType="com.goblin.BIbackend.model.entity.InstallRequests">DELETE FROM install_requests where id = #{id}</delete><update id="update1" parameterType="com.goblin.BIbackend.model.entity.InstallRequests">UPDATE install_requestsset user_id = #{userId},request_date = #{requestDate},status = #{status},description = #{description}WHERE id = #{id}</update>
</mapper>

2.4 编写 Service 接口：

定义业务逻辑的接口，声明服务层的方法。

package com.goblin.BIbackend.service;import com.goblin.BIbackend.model.entity.InstallRequests;
import com.baomidou.mybatisplus.extension.service.IService;/**
* @author **
* @description 针对表【install_requests】的数据库操作Service
* @createDate 2024-07-07 00:04:57
*/
public interface InstallRequestsService extends IService<InstallRequests> {InstallRequests select2(Long id);InstallRequests insert2(InstallRequests installRequests);void delete2(Long id);InstallRequests update2(InstallRequests installRequests);}

2.5 编写 Service 实现类（ServiceImpl）：

实现 Service 接口中定义的方法，调用 Mapper 接口进行数据访问。

package com.goblin.BIbackend.service.impl;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.goblin.BIbackend.model.entity.InstallRequests;
import com.goblin.BIbackend.service.InstallRequestsService;
import com.goblin.BIbackend.mapper.InstallRequestsMapper;
import org.springframework.stereotype.Service;import javax.annotation.Resource;/**
* @author **
* @description 针对表【install_requests】的数据库操作Service实现
* @createDate 2024-07-07 00:04:57
*/@Service
public class InstallRequestsServiceImpl extends ServiceImpl<InstallRequestsMapper, InstallRequests>implements InstallRequestsService{@Resourceprivate InstallRequestsMapper mapper;@Overridepublic InstallRequests select2(Long id) {return mapper.select1(id);}@Overridepublic InstallRequests insert2(InstallRequests installRequests) {mapper.insert1(installRequests);return installRequests;}@Overridepublic void delete2(Long id) {mapper.delete1(id);}@Overridepublic InstallRequests update2(InstallRequests installRequests) {mapper.update1(installRequests);return installRequests;}}

2.6 编写 Controller 类：

创建 RESTful API 或 MVC 控制器，处理 HTTP 请求并调用 Service 层。

package com.goblin.BIbackend.controller;import com.goblin.BIbackend.common.BaseResponse;
import com.goblin.BIbackend.common.ResultUtils;
import com.goblin.BIbackend.model.entity.InstallRequests;
import com.goblin.BIbackend.service.InstallRequestsService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.*;import javax.annotation.Resource;@RestController
@RequestMapping("/installRequests")
@Slf4j
public class InstallRequestsController {@Resourceprivate InstallRequestsService iRS;@GetMapping("/select2")public BaseResponse<InstallRequests> select2(Long id) {log.info("查询电表安装请求: {}", id);InstallRequests installRequests = iRS.select2(id);return ResultUtils.success(installRequests);}@PostMapping("/insert2")public BaseResponse<InstallRequests> insert2(@RequestBody InstallRequests installRequests) {log.info("新增电表安装请求: {}", installRequests);InstallRequests insert = iRS.insert2(installRequests);return ResultUtils.success(insert);}@DeleteMapping("/delete2")public BaseResponse<Boolean> delete2(Long id) {log.info("删除电表安装请求: {}", id);iRS.delete2(id);return ResultUtils.success(true);}@PutMapping("/update2")public BaseResponse<InstallRequests> update2(@RequestBody InstallRequests installRequests) {log.info("更新电表安装请求: {}", installRequests);iRS.update2(installRequests);return ResultUtils.success(installRequests);}
}
