我无法弄清楚如何使用Reactor正确实现发布者/订阅者方案。我有一个有效的解决方案,但实施对我来说似乎不正确:
我的问题是我需要手动实现发布者注册订阅者并传递事件:
public void publishQuotes(String ticker) throws InterruptedException {
// [..] Here I generate some "lines" to be publisher
for (Subscriber<? super String> subscriber : subscribers) {
lineList.forEach(line -> subscriber.onNext(line));
}
}
@Override
public void subscribe(Subscriber<? super String> subscriber) {
subscribers.add(subscriber);
}
然后,我有一个WorkQueue处理器(应该是消费者):
WorkQueueProcessor<String> sink = WorkQueueProcessor.create();
// Here I subscribe to my publiser
publisher.subscribe(sink);
// Creates a Reactive Stream from the processor (having converted the lines to Quotations)
Flux<StockQuotation> mappedRS = sink.map(quotationConverter::convertHistoricalCSVToStockQuotation);
// Here I perform a number of stream transformations
// Each call to consume will be executed in a separated Thread
filteredRS.consume(i -> System.out.println(Thread.currentThread() + " data=" + i));
它工作得很好但是很丑陋。 In this example取自Spring Guides,它们使用EventBus将事件从发布者路由到消费者,但是当我尝试将其与处理器链接时,我得到了这个编译器错误:
eventBus.on($("quotes"),sink);
The method on(Selector, Consumer<T>) in the type EventBus is not applicable for the arguments (Selector<String>, WorkQueueProcessor<String>)
我迷失在这里,将发布商与处理器链接的最佳方法是什么?你会推荐使用EventBus吗?如果是这样,那么适当的调用是什么?
谢谢!

如果您使用EventBus,您将通过
