CONSUL问题修正(SINGLETON)

最近在工作的时候发生了一些多执行续配合CONSUL的问题
解了以后发现singleton的重要

1. static void Main(string[] args)
   
2.         {
   
3. 
   
4.             Task.Run(() => Console.WriteLine(ConfigStore.Amigo.CategoryIDs));
   
5.             Task.Run(() => Console.WriteLine(ConfigStore.Common.ApiPath2));
   
6.             Task.Run(() => Console.WriteLine(ConfigStore.Common.ApiPathByB2B2));
   
7.             Task.Run(() => Console.WriteLine(ConfigStore.Common.AuthAPIName));
   
8.             Task.Run(() => Console.WriteLine(ConfigStore.Common.CreateOrderToken));
   
9.             Task.Run(() => Console.WriteLine(ConfigStore.Common.JWTSecret));
   
10.             Task.Run(() => Console.WriteLine(ConfigStore.Common.LdapPath));
    
11.             Task.Run(() => Console.WriteLine(ConfigStore.Common.IsTestCase));
    
12.             Console.Read();
    
13.     }

以这段CODE来模拟同时间呼叫 原本的写法在建立的时候是这样做

1. Console.WriteLine("中間");
   
2.                     if (signalled = mutex.WaitOne(2000))
   
3.                     {
   
4.                         Console.WriteLine("裡面");
   
5.                         if (instance == null)
   
6.                         {
   
7.                             Console.WriteLine("很裡面");
   
8.                             instance = new ConsulConfigStore();
   
9.                         }
   
10.                     }

发生了两秒过去了会让NULL的物件继续往前走
所以改回了这样的写法

1. Console.WriteLine("中間");
   
2.                     if (instance == null)
   
3.                     {
   
4.                         lock (o)
   
5.                         {
   
6.                             Console.WriteLine("裡面");
   
7.                             if (instance == null)
   
8.                             {
   
9.                                 Console.WriteLine("很裡面");
   
10.                                 instance = new ConsulConfigStore();
    
11.                             }
    
12.                         }
    
13. 
    
14.                     }

回归用Lock搞定
