WCF的实例模式PerSession怎么使用呢

0
悬赏园豆:5 [待解决问题]

我有两个服务,一个是单实例一个是PerSession,

问题:是IService2实例模式PerSession每次执行GetData的GetHashCode都不一样,说明每次都实例化一次了

我的目的是:想让用户请求IService2服务时,如果2分钟一直不作任何操作(请求)了才注销实例,否则不注销实例,使用相同实例。如果用户使用IService1服务都是相同的实例,整个服务只实例一次,这步已经实现了

IService1是单实例模式

 [ServiceContract(Namespace = "http://www.artech.com/")]
    public interface IService1
    {
        [WebInvoke(Method = "*")]
        [OperationContract]
        string GetData();
}
   [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single)]
    public class Service1 : IService1
    {
      public string GetData()
        {
            return string.Format("You GetHashCode: {0}", this.GetHashCode());
        }
} 

 

IService2是PerSession

 [ServiceContract(SessionMode = SessionMode.Allowed)]  
    public interface IService2
    {
        [WebGet]
        [OperationContract]
        string GetData();
}
 [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Single)]
    public class Service2 : IService2
    {
         public Service2()
         { 
         
         }
        public string GetData()
        {
            return string.Format("You GetHashCode: {0}", this.GetHashCode());
        }
}

你这样的需求是怎么来的?

原生wcf好像没法做到你的要求吧。

你要么在需要hashcode一致的对象外再包层,然后由那层对你这个对象做滑动过期的缓存。

获取hashcode的时候由缓存对象提供
