我们有一个包含多种服务的 Service Fabric 服务项目:Actor、有状态服务和无状态服务组合成一个 ServiceManifest。
两个有状态服务不起作用:调用了构造函数,创建了通信侦听器(通过远程处理),但没有调用 RunAsync 方法。
从 ServiceManifest.xml 中删除端点列表后,服务再次开始工作。但是现在我们想知道为什么以及如何工作。有人可以解释一下吗?
为了说明,相关部分是
<Resources>
<Endpoints>
<Endpoint Name="WebServiceEndpoint" Type="Input" Protocol="http" Port="80" />
<Endpoint Name="StatelessServiceEndpoint1" Type="Input" Protocol="http" Port="10101" />
<Endpoint Name="ActorServiceEndpoint1" />
<Endpoint Name="ActorServiceReplicatorEndpoint1" />
<Endpoint Name="ActorServiceEndpoint2" />
<Endpoint Name="ActorServiceReplicatorEndpoint2" />
<Endpoint Name="ActorServiceEndpoint3" />
<Endpoint Name="ActorServiceReplicatorEndpoint3" />
<Endpoint Name="ActorServiceEndpoint4" />
<Endpoint Name="ActorServiceReplicatorEndpoint4" />
<Endpoint Name="StatefulServiceEndpoint1" Type="Input" Protocol="http" />
<Endpoint Name="StatefulServiceReplicatorEndpoint1" />
<Endpoint Name="StatefulServiceEndpoint2" Type="Input" Protocol="http" />
<Endpoint Name="StatefulServiceReplicatorEndpoint2" />
<Endpoint Name="StatelessServiceEndPoint2" Type="Input" Protocol="http" />
</Endpoints>
</Resources>
改成这个后
<Resources>
<Endpoints>
<Endpoint Name="WebServiceEndpoint" Type="Input" Protocol="http" Port="80" />
<Endpoint Name="StatelessServiceEndpoint1" Protocol="http" />
<Endpoint Name="ActorServiceReplicatorEndpoint1" />
<Endpoint Name="ActorServiceReplicatorEndpoint2" />
<Endpoint Name="ActorServiceReplicatorEndpoint3" />
<Endpoint Name="ActorServiceReplicatorEndpoint4" />
<Endpoint Name="StatefulServiceReplicatorEndpoint1" />
<Endpoint Name="StatefulServiceReplicatorEndpoint2" />
</Endpoints>
</Resources>
一切正常。但为什么?
编辑 完整的 ServiceManifest 是这样的:
