如果找到/存在实例，只使用Redis进行缓存？

Question

我想使用Redis进行缓存，但如果在运行时未找到Redis实例，我仍然希望我的服务能够正常工作。

在实践中是否有这样的例子？

你可以做这样的事情在你的APPHOST配置方法如下

public override void Configure(Container container) 
{ 
    ... 
    try 
    { 
     var redisManager = new PooledRedisClientManager("localhost:6379"); 
     // do some sort of test to see if we can talk to the redis server 
     var client = redisManager.GetCacheClient(); 
     var fakeKey = "_________test_______"; 
     client.Add(fakeKey, 1); 
     client.Remove(fakeKey); 
        // if it worked register the cacheClient 
     container.Register(c => redisManager.GetCacheClient()).ReusedWithin(ReuseScope.None); 
    } 
    catch (Exception ex) 
    { 
     // fall back to in memory cache 
     // Log some sort of warning here. 
     container.Register<ICacheClient>(c => new MemoryCacheClient()); 
    } 
    ... 
}
