连接字符串 appsetting.json
"ConnectionStrings": {
"DefaultConnection": "Server=DESKTOP-DABHN6U\\MSSQLSERVER2014;uid=sa;pwd=Lz38275292;database=SPA;MultipleActiveResultSets=true;"

在Program.cs中注册
var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");
builder.Services.AddDbContext<ApplicationDbContext>(options =>
