如何在启动.Net Core Web API服务应用程序时从mysql数据库加载数据？

"ConnectionStrings": {
  "DefaultConnection": "server=localhost;port=3306;database=mydatabase;user=root;password=mypassword"
}

public class MyDbContext : DbContext
{
    public DbSet<MyModel> MyModels { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseMySQL(Configuration.GetConnectionString("DefaultConnection"));
    }
}

services.AddDbContext<MyDbContext>();

private readonly MyDbContext _dbContext;

public MyController(MyDbContext dbContext)
{
    _dbContext = dbContext;
}

public async Task<IActionResult> GetData()
{
    var data = await _dbContext.MyModels.ToListAsync();
    return Ok(data);
}
