1.克隆

2.修改配置信息

2.1.數據庫配置信息

2.2.修改生成器配置信息中包名等

3.啟動生成器項目

4.頁面訪問

5.生成代碼步驟

a.全選
b.點擊生成代碼按鈕
c.下載代碼壓縮包

6.導入生成的代碼

導入后發現好多報紅

7.修改

新建gulimall-common項目

8.啟動

在gulimall-product項目的pom文件中引入gulimall-common

<dependency><groupId>com.atguigu.gulimall</groupId><artifactId>gulimall-common</artifactId><version>0.0.1-SNAPSHOT</version></dependency>

現在gulimall-product不報紅,接著配置mybatis-plus，詳情請參考mybatis-plus官網添加鏈接描述

8.1.在 application.yml 配置文件中添加 H2 數據庫的相關配置

spring:datasource:username: rootpassword: rooturl: jdbc:mysql://192.168.56.10:3306/gulimall_pmsdriver-class-name: com.mysql.jdbc.Drivermybatis-plus:mapper-locations: classpath:/mapper/**/*.xmlglobal-config:db-config:id-type: auto #主鍵自增server:port: 10000 logging:level:com.atguigu.gulimall: debug

8.2.啟動類上加MapperScan，掃描 Mapper 文件夾

package com.atguigu.gulimall.product;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication @MapperScan("com.atguigu.gulimall.product.dao") public class GulimallProductApplication {public static void main(String[] args) {SpringApplication.run(GulimallProductApplication.class, args);}}

8.3.測試

package com.atguigu.gulimall.product;import com.atguigu.gulimall.product.entity.BrandEntity; import com.atguigu.gulimall.product.service.BrandService; import org.junit.jupiter.api.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner;@SpringBootTest class GulimallProductApplicationTests {@AutowiredBrandService brandService;@Testpublic void testBrand() {BrandEntity brandEntity = new BrandEntity(); // brandEntity.setName("Iphone 13"); // brandEntity.setDescript("蘋果2021年新款"); // brandService.save(brandEntity);// brandEntity.setBrandId(1L); // brandEntity.setSort(1); // brandService.updateById(brandEntity);BrandEntity brand = brandService.getById(1L);System.out.println(brand);System.out.println("--------------------success ！-----------------------");}}
