无法将对象添加到Velocity缓存

我刚安装好 Velocity

连接到缓存主机的代码(工作正常):

// Define Array for 1 cache host.
ServerEndPoint[] servers = new ServerEndPoint[1];

// Specify Cache Host Details 
servers[0] = new ServerEndPoint(
       "COMPUTERNAME" /* Host  */, 
       22233 /* Port */, 
       "DistributedCacheService" /* Service name */);

// Pass configuration settings to CacheFactory constructor.
m_cacheFactory = new CacheFactory(servers, 
       true /* Use routing client */, 
       false /* No local cache */);

// Get the cache (works fine).
Cache cache = m_cacheFactory.GetCache("MyCache");

将对象添加到缓存的我的代码(不起作用):

// Get the cache.
Cache cache = m_cacheFactory.GetCache("MyCache");

// Create the item to put in the cache.
Product product = new Product();
product.Sku = "10000";
product.Name = "My Product";

// Put the object in the cache (The add method doesn't work either).
cache.Put(product.Sku /* Key */, product /* Value */);

通过集群管理员界面,我已经验证了缓存主机是否正在运行以及缓存本身是否存在。

有人知道问题出在哪里吗?
