基础-02快速开发（人人开源）

一、创建maven工程

二、人人开源

2.1 人人开源前后台项目搭建

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、renren-fast（后台服务）

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/”

2、renren-fast-vue（前端项目）

安装node.js，并且安装仓库

npm config set registry http://registry.npm.taobao.org/
PS D:\tmp\renren-fast-vue> npm config set registry http://registry.npm.taobao.org/
PS D:\tmp\renren-fast-vue> npm install
npm WARN ajv-keywords@1.5.1 requires a peer of ajv@>=4.10.0 but none is installed. You must install peer dependencies yourself.
npm WARN sass-loader@6.0.6 requires a peer of node-sass@^4.0.0 but none is installed. You must install peer dependencies yourself.

2.2 人人开源代码生成器

1、clone项目

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、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_

3、运行项目

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。

三、其他

1、npm下载失败解决方法

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”

使用淘宝镜像

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
