java akka：向祖父母发回消息,java,akka,Java,Akka,我创造了3个级别的演员。一级是主管演员。主管参与者将向Level2参与者触发消息，并根据收到的消息类型，根据子参与者（Level1和Level2）返回的响应采取行动。以下是主管的代码 if (message instanceof OutBoundDataExportDTO) { // This to trigger query processor OutBoundDataExportDTO data = OutBoundDataExportDTO.class.cast(me

我创造了3个级别的演员。一级是主管演员。主管参与者将向Level2参与者触发消息，并根据收到的消息类型，根据子参与者（Level1和Level2）返回的响应采取行动。以下是主管的代码

if (message instanceof OutBoundDataExportDTO) {
    // This to trigger query processor

    OutBoundDataExportDTO data = OutBoundDataExportDTO.class.cast(message);
    LOGGER.info("Received:  " + data.toString());
    ActorRef ruleInstExportActor = actorSystem
        .actorOf(Props.create(OutboundsQueryActor.class, applicationContext)
        .withRouter(new RoundRobinPool(5)));
    ruleInstExportActor.tell(data, getSelf());

} else if (message instanceof TaskCompleteMsg) {
    TaskCompleteMsg taskCompleteMsg= TaskCompleteMsg.class.cast(message);
    taskService.update(taskCompleteMsg);
}

在2级参与者中，工作被委托给某个处理器。此处理器将产生另一个参与者（3级参与者）。现在，我需要将taskcomplete的响应从Level 3 actor返回到Level 1 actor（supervisor actor），以便它根据响应采取行动

下面是Level2 actor的示例代码：

if (message instanceof Level1ActorMessage) {
     OutboundQueryProcessor queryProcessor =  queryProcessorFactory
         .getQueryProcessor(queryName);
     response = queryProcessor.executeQuery(templateId, queryData, task);

} else if (message instanceof Level3ActorTaskCompleteMsg) { // This is the response from Level 3 actor, once it has completed 
    ActorRef parent = getContext().parent(); // This gives me the   parent(Level2)
    // How do i send it back to its parent
    // parent.tell(returnResponse, parent);
}

if (message instanceof Level1ActorMessage) {
    OutboundQueryProcessor queryProcessor = queryProcessorFactory.getQueryProcessor(queryName);
    response = queryProcessor.executeQuery(templateId, queryData, task);

} else if(message instanceof Level3ActorTaskCompleteMsg){// This is the response from Level 3 actor, once it has completed 
    ActorRef parent = getContext().parent();// This gives me the   parent(Level2)
    //How do i send it back to its parent
    //   parent.tell(returnResponse, parent);
}

如何将第三级演员（儿童）的回复发送回祖父母（第一级）

在Level2 actor的代码段中：

if (message instanceof Level1ActorMessage) {
     OutboundQueryProcessor queryProcessor =  queryProcessorFactory
         .getQueryProcessor(queryName);
     response = queryProcessor.executeQuery(templateId, queryData, task);

} else if (message instanceof Level3ActorTaskCompleteMsg) { // This is the response from Level 3 actor, once it has completed 
    ActorRef parent = getContext().parent(); // This gives me the   parent(Level2)
    // How do i send it back to its parent
    // parent.tell(returnResponse, parent);
}

if (message instanceof Level1ActorMessage) {
    OutboundQueryProcessor queryProcessor = queryProcessorFactory.getQueryProcessor(queryName);
    response = queryProcessor.executeQuery(templateId, queryData, task);

} else if(message instanceof Level3ActorTaskCompleteMsg){// This is the response from Level 3 actor, once it has completed 
    ActorRef parent = getContext().parent();// This gives me the   parent(Level2)
    //How do i send it back to its parent
    //   parent.tell(returnResponse, parent);
}

您有一行

ActorRef parent=getContext（）.parent（）；//这将为我提供父级（Level2）

，它为Level2的父级（即Level1）提供ActorRef，它是Level3的祖父母

因此，如果您想告诉Level1 Level3已经完成，那么在Level2 actor中，您可以使用：

parent.tell(message, getSelf());

这将把

Level3ActorTaskCompleteMsg

传递到Level1，发送者将是Level2，或者您可以使用：

parent.forward(message, getContext());

它将把

Level3ActorTaskCompleteMsg

转发给Level1，当Level1是Level3时，即它的孙辈

无论采用哪种方式，您都将实现将

Level3ActorTaskCompleteMsg

从Level3发送到Level1的祖父母的目标

请参见Level2 actor代码片段中的

：

if (message instanceof Level1ActorMessage) {
     OutboundQueryProcessor queryProcessor =  queryProcessorFactory
         .getQueryProcessor(queryName);
     response = queryProcessor.executeQuery(templateId, queryData, task);

} else if (message instanceof Level3ActorTaskCompleteMsg) { // This is the response from Level 3 actor, once it has completed 
    ActorRef parent = getContext().parent(); // This gives me the   parent(Level2)
    // How do i send it back to its parent
    // parent.tell(returnResponse, parent);
}

if (message instanceof Level1ActorMessage) {
    OutboundQueryProcessor queryProcessor = queryProcessorFactory.getQueryProcessor(queryName);
    response = queryProcessor.executeQuery(templateId, queryData, task);

} else if(message instanceof Level3ActorTaskCompleteMsg){// This is the response from Level 3 actor, once it has completed 
    ActorRef parent = getContext().parent();// This gives me the   parent(Level2)
    //How do i send it back to its parent
    //   parent.tell(returnResponse, parent);
}
