1. renren-fast-vue/renren-fast

https://gitee.com/renrenio

1587609877028

克隆到本地：

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

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

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/”

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！！！

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：

2. renren-generator

1.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

2.配置renren-generator中的application.yml

url: jdbc:mysql://192.168.56.10:3306/gulimall-pms?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
username: root
password: root

3.修改配置

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

#代码生成器，配置信息

# 主目录
mainPath=com.bigdata
#包名
package=com.bigdata.gulimall
#模块名
moduleName=product
#作者
author=cosmoswong
#Email
[email protected]
#表前缀(类名不会包含表前缀) # 我们的pms数据库中的表的前缀都pms
# 如果写了表前缀，每一张表对于的javaBean就不会添加前缀了
tablePrefix=pms_

（这里乱码的百度IDEA设置properties编码）

4.运行“renren-generator”

访问：<http://localhost:80/

1587638853416

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

1587638968519

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

1587657745923

它的数据类型是“longblob”类型，逆向工程后，对应的数据类型未知：

1587657812283

这个问题该要怎么解决？

5.配置项目application.yml

spring:
  datasource:
    username: root
    password: root
    url: jdbc:mysql://192.168.56.10:3306/gulimall-pms?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
    driver-class-name: com.mysql.jdbc.Driver

# MapperScan
# sql映射文件位置
mybatis-plus:
  mapper-locations: classpath:/mapper/**/*.xml
  global-config:
    db-config:
      id-type: auto

classpath 和 classpath* 区别：
classpath：只会到你的class路径中查找找文件;
classpath*：不仅包含class路径，还包括jar文件中(class路径)进行查找
classpath*的使用：当项目中有多个classpath路径，并同时加载多个classpath路径下（此种情况多数不会遇到）的文件，就发挥了作用，如果不加，则表示仅仅加载第一个classpath路径。

6.主启动类上加上注解@MapperScan()

扫描*Mapper.java文件

7.测试

@SpringBootTest
class gulimallProductApplicationTests {
    
    
    @Autowired
    BrandService brandService;

    @Test
    void contextLoads() {
    
    
        BrandEntity brandEntity = new BrandEntity();
        brandEntity.setDescript("哈哈1哈");
        brandEntity.setName("华为");
        brandService.save(brandEntity);
        System.out.println("保存成功");
    }
}
