前言：最近写项目，发现了一些很有意思的功能，想写文章，录视频把这些内容记录下。但这些功能太零碎，如果为每个功能都单独搭建一个项目，这明显不合适。于是我想，就搭建一个项目，把那些我想将的小功能全部整合到一起。实现 搭一次环境，处处使用。
本文主要实现以下功能
- 集成人人代码生成器【后端】
已录制视频
视频链接
仓库地址
https://github.com/xuhuafeifei/fgbg-font-and-back.git
1. 克隆renren-generator
git clone https://gitee.com/renrenio/renren-generator.git
2. 配置项目信息
点击/resource/generator.properties
将下述信息按照自己的需求进行配置
本文涉及到的项目，mainPath等参数填写如下
不知道mainPath等参数什么意思的，可以看看template目录下，Controller.java.vm这个模板类中的代码
tip:
- package：包名
- moduleName: 模块名
- mainPath：主路径
我们当前设置下，目录结构如下
- com - fgbg - test 【模块名】 - controller - service - entity ... - common 【通用模块】 ...后续介绍
3. 配置数据库信息
代码生成器是依据数据库信息，来生成对应的增删改查代码。因此，我们需要设置我们想要生成增删改查代码的数据库信息
点击application.yml，配置url，username，password
4. 启动项目
在浏览器中输入localhost:80，启动项目前端
在菜单栏中选择renren-fast，在界面中勾选需要生成对应代码的数据库表，点击生成代码即可
5. 创建springboot项目
5.1 pom.xml
我使用的是springboot2.7.5，jdk8

5.2 创建包结构
因为我们的mainPath是com.fgbg【详见第2部分】，所以创建的时候包结构创建2层即可
具体如下
TestApplication.java 启动类
package com.fgbg;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
5.3 编写application.yml
application.yml 启动环境为dev

5.4 将生成代码集成到项目中
解压缩文件，将文件中的main文件夹全部cv覆盖项目中的main文件夹
覆盖springboot项目的main模块
完美集成！
但点击CouresController，会发现有报错
这是因为项目中缺少common模块导致的
5.5 集成common模块
common模块的官方做法是，从renren-fast后端项目中cv过来。但官方的代码cv过来会出现包模块错误的问题，而且功能冗余，兼容性不太好。所以使用我自己整理好的common模块，具体获取方式为关注微信公众号 一只学Java的飞鸽呀，回复common，即可获取common代码
现在，我们将common集成到项目中
重点：ctrl+shift+r，用idea自带的全局替换功能，将com.zbg.common替换成我们自己项目中，common模块的路径com.fgbg.common
现在Controller不报错了，几乎都没咋改动代码，完美集成
5.6 启动项目
测试查询接口
成功！
