.Net Core WebAPi-SqlServer切换Mysql,实现CodeFirst

项目需要从SqlServer切换到Mysql,遇到了一些坑,作为记录
 
(1)Nuget安装
Microsoft.EntityFrameworkCore.Design
Microsoft.EntityFrameworkCore.Relational
Microsoft.EntityFrameworkCore.Tools
Pomelo.EntityFrameworkCore.MySql
 
 
(2)修改连接字符串“appsettings.json”
1 "ConnectionStrings": {
2     //Sqlserver连接字符串
3     //"CoreFrameContext": "Server=.;DataBase=数据库名称;uid=sa;pwd=密码"
4     "CoreFrameContext": "Data Source=localhost;Database=名称;User ID=root;Password=密码;pooling=true;CharSet=utf8;port=3306;sslmode=none"
5   },
注:连接字符串的Data Source不能写成IP,否则会报错
 
(3)修改“Startup.cs”,找到ConfigureServices
1 //SqlServer
2  services.AddDbContext<NetCoreFrameDBContext>(opt =>  opt.UseSqlServer(Configuration.GetConnectionString("CoreFrameContext")));
3 //Mysql
4  services.AddDbContext<NetCoreFrameDBContext>(opt =>  opt.UseMySQL(Configuration.GetConnectionString("CoreFrameContext")));
5  
 
(4)命令行迁移
打开“工具”-》“Nuget包管理器”-》“程序包管理器控制台”
Add-Migration  迁移名称
update-database
