1、在data里面新建个Entity文件用于存放表映射，设计数据库，执行如下语句
Scaffold-DbContext -Force "server=.;user=sunyong;password=1qaz!QAZ;database=hr;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir /Entity
将在Entity文件下面自动创建实体，可直接使用
创建个邮件类用于接收配置的邮件信息
public class email
{
public string token { get; set; }
public string sendname { get; set; }
public string sendmail { get; set; }
public string acceptmail { get; set; }
}
（实体类太多，最后会放到git上面）
2、在service创建CurrrentUser/CurrentUsers类，简单记录登录着信息
public class CurrentUsers
{
private static IHttpContextAccessor _httpContextAccessor;
private static ISession _session => _httpContextAccessor.HttpContext.Session;
public static void Configure(IHttpContextAccessor httpContextAccessor) {
_httpContextAccessor = httpContextAccessor;
}
/// <summary>
///用户编号
/// </summary>
public static int UserId { get; set; }
/// <summary>
///用户名
/// </summary>
public static string UserName { get; set; }
}
3、在service下新增Filters文件夹，Filters下面创建AdminOnlyFilter，MustLoginFilter类
public class AdminOnlyFilter : IPageFilter, IActionFilter
{
public void OnActionExecuted(ActionExecutedContext context) { }
public void OnActionExecuting(ActionExecutingContext context) { }
public void OnPageHandlerExecuted(PageHandlerExecutedContext context) { }
public void OnPageHandlerExecuting(PageHandlerExecutingContext context) { }
public void OnPageHandlerSelected(PageHandlerSelectedContext context) { }
}
public class MustLoginFilter : IPageFilter, IActionFilter
{
public void OnActionExecuted(ActionExecutedContext context) { }
public void OnActionExecuting(ActionExecutingContext context) { }
public void OnPageHandlerExecuted(PageHandlerExecutedContext context) { }
public void OnPageHandlerExecuting(PageHandlerExecutingContext context) { }
public void OnPageHandlerSelected(PageHandlerSelectedContext context) { }
}
适合小白的Demo_easyui+core3第二章实体类创建
