本文主要是介绍第162天学习打卡(谷粒商城4 逆向生成所有微服务的CRUD),对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

逆向生成所有微服务的CRUD代码

Product

把在Git上克隆下的RENREN-FAST-VUE拖入Visual Studio Code中之后,执行以下命令

 npm install 
 npm run dev

执行成功后会出现: I Your application is running here: http://localhost:8001,点击这个链接进行查看。

在码云上搜索人人开源,选择下面这个:

renren-generator: 人人开源项目的代码生成器,可在线生成entity、xml、dao、service、vue、sql代码,减少70%以上的开发任务 (gitee.com)

在Git里面把下面克隆下来

 $ git clone https://gitee.com/renrenio/renren-generator.git
 ​

 

image-20210619164005326

把克隆下来的renren-generator里面的.git文件删除,然后放入gulimall这个总文件下

image-20210619172409819

生成代码的压缩包解压把里面的main文件夹复制到gulimall-product里面的main

image-20210619174118865

image-20210619174334793

创建一个maven模块

image-20210619185900432

创建的gulimall-common里面需要的文件我们从renren-fast里面拷贝

在gulimall-product中的resources下创建application.yaml文件

application.yaml

 spring:
   datasource:
     username: root
     password: 123456
     url: jdbc:mysql://数据库连接地址:3306/gulimall_pms?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
     driver-class-name: com.mysql.cj.jdbc.Driver
 mybatis-plus:
   mapper-locations: classpath:/mapper/**/*.xml
   global-config:
     db-config:
       id-type: auto
 server:
   port: 10000
 ​
 ​

在gulimall.product的Test里面进行测试1:

 package com.doudou.gulimall.product;
 ​
 import com.doudou.gulimall.product.entity.BrandEntity;
 import com.doudou.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;
 ​
 @RunWith(SpringRunner.class)
 @SpringBootTest
 class GulimallProductApplicationTests {
     @Autowired
     BrandService brandService;
 ​
     @Test
    public void contextLoads() {
         BrandEntity brandEntity = new BrandEntity();
         brandEntity.setName("华为");
         brandService.save(brandEntity);
         System.out.println("保存成功...");
     }
 ​
 }
 ​

输出结果:

在gulimall.product的Test里面进行测试2:

 package com.doudou.gulimall.product;
 ​
 import com.doudou.gulimall.product.entity.BrandEntity;
 import com.doudou.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;
 ​
 @RunWith(SpringRunner.class)
 @SpringBootTest
 class GulimallProductApplicationTests {
     @Autowired
     BrandService brandService;
 ​
     @Test
    public void contextLoads() {
         BrandEntity brandEntity = new BrandEntity();
         brandEntity.setBrandId(1L);
         brandEntity.setDescript("华为");
 //        brandEntity.setName("华为");
 //        brandService.save(brandEntity);
 //        System.out.println("保存成功...");
         brandService.updateById(brandEntity);
 ​
     }
 ​
 }
 ​

结果显示

在gulimall.product的Test里面进行测试3:

 package com.doudou.gulimall.product;
 ​
 import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
 import com.doudou.gulimall.product.entity.BrandEntity;
 import com.doudou.gulimall.product.service.BrandService;

 @RunWith(SpringRunner.class)
 @SpringBootTest
 class GulimallProductApplicationTests {
     @Autowired
     BrandService brandService;
 ​
     @Test
    public void contextLoads() {
 //        BrandEntity brandEntity = new BrandEntity();
 //        brandEntity.setBrandId(1L);
 //        brandEntity.setDescript("华为");
 ////        brandEntity.setName("华为");
 ////        brandService.save(brandEntity);
 ////        System.out.println("保存成功...");
 //        brandService.updateById(brandEntity);
 ​
         List<BrandEntity> list = brandService.list(new QueryWrapper<BrandEntity>().eq("brand_id", 1L));
         list.forEach((item)->{
             System.out.println(item);
 ​
         });
 ​
 ​
     }
