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-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

image-20210619195358286

image-20210619201751258

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);

        brandService.updateById(brandEntity);

    }

}
