谷粒商城环境准备 docker版

1）安装vagrant

2）安装Centos7

$ vagrant init centos/7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

执行完上面的命令后，会在用户的家目录下生成Vagrantfile文件。

$ vagrant up

下载镜像过程比较漫长，也可以采用先用下载工具下载到本地后，然后使用“ vagrant box add ”添加，再“vagrant up”即可

#将下载的镜像添加到virtualBox中

4. 创建maven工程

5. 执行sql脚本

gulimall_oms.sql
gulimall_pms.sql
gulimall_sms.sql
gulimall_ums.sql
gulimall_wms.sql
pms_catelog.sql
sys_menus.sql

6. clone 人人开源

https://gitee.com/renrenio

克隆到本地：

git clone https://gitee.com/renrenio/renren-fast-vue.git

git clone https://gitee.com/renrenio/renren-fast.git
1
2
3

将拷贝下来的“renren-fast”删除“.git”后，拷贝到“gulimall”工程根目录下，然后将它作为gulimall的一个module

创建“gulimall_admin”的数据库，然后执行“renren-fast/db/mysql.sql”中的SQl脚本

修改“application-dev.yml”文件，默认为dev环境，修改连接mysql的url和用户名密码

spring:
    datasource:
        type: com.alibaba.druid.pool.DruidDataSource
        druid:
            driver-class-name: com.mysql.cj.jdbc.Driver
            url: jdbc:mysql://192.168.137.14:3306/gulimall_admin?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
            username: root
            password: root

启动“gulimall_admin”，然后访问“http://localhost:8080/renren-fast/”

安装node.js，并且安装仓库

常见问题1：“Module build failed: Error: Cannot find module 'node-sass”

运行过程中，出现“Module build failed: Error: Cannot find module 'node-sass’报错问题”，解决方法

用npm install -g cnpm --registry=https://registry.npm.taobao.org ，从淘宝镜像那下载，然后cnpm下载成功。

最后输入cnpm install node-sass --save。npm run dev终于能跑起来了！！！

常见问题2：cnpm - 解决 " cnpm : 无法加载文件 C:\Users\93457\AppData\Roaming\npm\cnpm.ps1，因为在此系统上禁止运行脚本。有关详细信息 。。。 "

https://www.cnblogs.com/500m/p/11634969.html

所有问题的根源都在“node_modules”，npm install之前，应该将这个文件夹删除，然后再进行安装和运行。

再次运行npm run dev恢复正常：

7. clone renren-generator

clone

https://gitee.com/renrenio/renren-generator.git

然后将该项目放置到“gulimall”的跟路径下，然后添加该Module，并且提交到github上

修改配置

renren-generator/src/main/resources/generator.properties

#代码生成器，配置信息

mainPath=com.bigdata
#包名
package=com.bigdata.gulimall
moduleName=product
#作者
author=cosmoswong
#Email
email=cosmoswong@sina.com
#表前缀(类名不会包含表前缀)
tablePrefix=pms_

运行“renren-generator”

访问：<http://localhost:80/

点击“renren-fast”，能够看到它将“renren-fast”的所有表都列举了出来：

选择所有的表，然后点击“生成代码”，将下载的“renren.zip”，解压后取出main文件夹，放置到“gulimall-product”项目的main目录中。

下面的几个module，也采用同样的方式来操作。

但是针对于“undo_log”，存在一个问题

它的数据类型是“longblob”类型，逆向工程后，对应的数据类型未知：

这个问题该要怎么解决？

8. 微服务注册中心

要注意nacos集群所在的server，一定要关闭防火墙，否则容易出现各种问题。

搭建nacos集群，然后分别启动各个微服务，将它们注册到Nacos中。

  application:
    name: gulimall-coupon
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.137.14

查看注册情况：

http://192.168.137.14:8848/nacos/#/serviceManagement?dataId=&group=&appName=&namespace=

9. 使用openfen

1)、引入open-feign

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
1
2
3
4

2)、编写一个接口，告诉SpringCLoud这个接口需要调用远程服务

修改“com.bigdata.gulimall.coupon.controller.CouponController”，添加以下controller方法：

    @RequestMapping("/member/list")
    public R memberCoupons(){
        CouponEntity couponEntity = new CouponEntity();
        couponEntity.setCouponName("discount 20%");
        return R.ok().put("coupons",Arrays.asList(couponEntity));
    }
1
2
3
4

6

新建“com.bigdata.gulimall.member.feign.CouponFeignService”接口

@FeignClient("gulimall_coupon")
public interface CouponFeignService {
    @RequestMapping("/coupon/coupon/member/list")
    public R memberCoupons();
}
1
2
3
4
5

修改“com.bigdata.gulimall.member.GulimallMemberApplication”类，添加上"@EnableFeignClients"：

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients(basePackages = "com.bigdata.gulimall.member.feign")
public class GulimallMemberApplication {

    public static void main(String[] args) {
        SpringApplication.run(GulimallMemberApplication.class, args);
    }
}
1
2
3
4
5
6
7
8
9

​ 声明接口的每一个方法都是调用哪个远程服务的那个请求

3)、开启远程调用功能

com.bigdata.gulimall.member.controller.MemberController

    @RequestMapping("/coupons")
    public R test(){
        MemberEntity memberEntity=new MemberEntity();
        memberEntity.setNickname("zhangsan");
        R memberCoupons = couponFeignService.memberCoupons();

        return memberCoupons.put("member",memberEntity).put("coupons",memberCoupons.get("coupons"));
    }

1
2
3
4
5
6

(4)、访问http://localhost:8000/member/member/coupons

停止“gulimall-coupon”服务，能够看到注册中心显示该服务的健康值为0：

再次访问：http://localhost:8000/member/member/coupons

启动“gulimall-coupon”服务，再次访问，又恢复了正常。
