偽Session這樣共用到Service

在顯示層用如下代碼，把需要存儲的值放到線程擁有者里，代碼如下

         var claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;
             var a =new  ClaimsIdentity();
             a.AddClaim(new Claim("UserId","150"));
            if (claimsPrincipal != null) claimsPrincipal.AddIdentity(a);

在Service層調用的時候如下：

  var claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;
            var userId= claimsPrincipal.Claims.FirstOrDefault(c => c.Type == "UserId").Value;

請問這樣把Seesion共用到Service可行嗎？
