一、数据库的排序和统一问题。utf8mb4和utf8的不同

1.1 发现问题

在我们小组的分工合作完，建好数据库表之后，合并的时候，发现有冲突。因为三个组员使用的Navicat，没有utf8，用的是默认的utf8mb4和utf8mb4_general_ci这两个字符集和排序规则。导致我们总和数据库的时候，发现问题。

1.2 解决问题-在idea中用sql生成器，生成sql语句，然后在里面修改

把每个表最后的utf8mb4修改为utf8后，保存，重新执行。

1.3 utf8和utf8mb4的区别

utf8 是 Mysql 中的一种字符集，只支持最长三个字节的 UTF-8字符，也就是 Unicode 中的基本多文本平面。要在 Mysql 中保存 4 字节长度的 UTF-8 字符，需要使用 utf8mb4 字符集，但只有 5.5.3 版本以后的才支持。
如果遇到 4 字节的字符就会出现错误了。三个字节的 UTF-8 最大能编码的 Unicode 字符是 0xFFFF，也就是 Unicode 中的基本多文平面（BMP）。也就是说，任何不在基本多文平面的 Unicode字符，都无法使用MySQL原有的 utf8 字符集存储。这些不在BMP中的字符包括哪些呢？最常见的就是Emoji 表情（Emoji 是一种特殊的 Unicode 编码，常见于 ios 和 android 手机上），和一些不常用的汉字，以及任何新增的 Unicode 字符等等。

二、若依前后端框架。代码生成器（还没研究懂，但有三个方案）

2.1 若依框架的优缺点（十分片面）

对于我来说，这是一个没有深入研究过的东西，是小组成员商讨然后使用。对于若依的前后端分离框架：
优点是：数据库的字段超级多，我们也需要相应的元素，和一些重复的代码开发，使用若依可以直接专注于代码的开发，前后端都已经是较为完善的了。
缺点是：对于刚接触若依框架的我们来说，很多模块，功能有点找不清，而且我们需要开发的话，固定在rouyi-system里面来写，需要花大量时间去继续研究代码的含义，以及如何去重新开一个模块，写自己的代码。（我知道，还是我业务能力低，大佬早就解决了，接触时间太少了，后续多接触，再回来改）。

2.2 若依框架的下载，安装和运行：

直接看大佬的吧：https://blog.csdn.net/moran_3346/article/details/131803190

2.3 遇到的问题（希望有人能帮到我）

我想独立出一个模块来写自己的代码，所以我创建了一个空模块，然后去重新写所有的配置
代码太多了，我只粘出部分重要的代码：

进程已结束，退出代码为 1

2.4 解决了的问题

2.4.1 xml中 type=、parameterType=报错，见图（这是修改过的了）

2.4.2 在我们的实体类上面增加一个注解@Alias(“TmsTb01”)：

2.4.3 @Alias（我的理解是别名）

使用前提
在配置文件中配置 type-aliases-package 告诉spring boot （项目）你改别名的包是哪里
如：type-aliases-package: com.ye.test.pojo

实体类使用方法

@Alias("oppo")
public class Teacher {
    private Integer id;
    private String name;

mapper.xml 使用方法
mapper.xml 文件中可以直接使用 oppo，代替 com.ye.test.pojo.Teacher
如：javaType=“oppo” resultType=“oppo” parameterType=“oppo”

注意：使用@Alias 起别名之后，mapper.xml 文件 不能再使用 Teacher/teacher，但可以使用全类名 com.ye.test.pojo.Teacher

2.5 使用mybatis-generator （没咋看懂，还有git上的代码生成器，和若依差不多。）

三、gitee

1 为什么使用到gitee了

因为我们小组开发，还使用到了gitee来进行代码的整理和下放，很久之前在黑马的视频里面使用过gitee对自己的代码进行推，拉，合并，今天重温一下。主要的使用场景还是在idea里面。

2 gitee的登录和创建仓库以及邀请组员

2.1 gitee官网：https://gitee.com/

2.2 然后创建仓库：

根据需求进行创建

2.3 邀请组员

打开自己的仓库，点击管理，然后仓库成员管理

然后就可以根据链接和二维码进行分享和邀请了！！！

2.4 推拉数据

推数据：

拉数据

从头拉项目

四、前端vue的下载修复和启动

被组员吐槽了，是一点前端不会啊哈哈哈

1 运行和下载npm run dev、npm install

2 下载完进行修复npm audit fix（好习惯！）

3 npm audit和npm audit fix的不同：

npm audit安全漏洞的扫描器
npm audit fix：自动修复漏洞的利器
npm audit fix要慎重使用，这个命令可能会引发依赖问题，比如A包依赖B包，结果B包强制更新后，A包的依赖找不到了。
所以，搭配使用：
我们来看一个具体的例子。假设你的项目中有一个名为“express”的依赖包，但是这个包存在一个已知的安全漏洞。当你运行npm audit时，它会报告这个漏洞并给出相应的警告信息。接下来，你就可以查看升级之后，是否会造成其他冲突，然后尝试运行npm audit fix来自动修复这个问题。系统会自动更新“express”依赖包的版本，将其升级到一个没有安全漏洞的版本。
