using System.Threading.Tasks;
using MySql.Data.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
namespace fjxw.model
{
public class CoreDbContext : DbContext
{
public virtual DbSet<sysuser> SysUser { get; set; } //创建实体类添加Context中

//protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
//{
// if (!optionsBuilder.IsConfigured)
// {
// optionsBuilder.UseMySQL(@"server=localhost;uid=root;pwd=123456;
// port=3306;database=fjxwcharge;sslmode=Preferred;");
// }
//}

public CoreDbContext(DbContextOptions<CoreDbContext> options) : base(options)
{
