MVC 4中使用ServiceStack.Redis实现Redis队列【错误日志并发处理】

HomeController.cs

 public class HomeController : Controller
    { 
        // GET: /Home/
        //1.怎样在MVC中捕获异常信息.

        public ActionResult Index()
        {
            int a = 2;
            int b = 0;
            int c = a / b;
            return View();
        }

    }

          redisClent.EnqueueItemOnList("errorException", filterContext.Exception.ToString());//将异常信息存储到Redis队列中了。
            filterContext.HttpContext.Response.Redirect("/error.html");
            base.OnException(filterContext);
        }


        public static PooledRedisClientManager CreateManager(string[] readWriteHosts, string[] readOnlyHosts)

运行结果如图:

---

站点的异常存储到Redis队列
cmd窗口端查询

---

从队列中获取异常数据记录到文本文件

cmd窗口端查询
