Spring integration DSL example of file polling inbound channel adapter

Question

Can't find an example anywhere using spring integration DSL only xml. Any pointers appreciated, also need the poller to trigger on file creation and modification

Answer 1

这个怎么样：

@Bean
public IntegrationFlow fileReadingFlow() {
    return IntegrationFlows
            .from(s -> s.file(tmpDir.getRoot()).patternFilter("*.sitest"),
                    e -> e.poller(Pollers.fixedDelay(100)))
            .transform(Transformers.fileToString())
            .channel(MessageChannels.queue("fileReadingResultChannel"))
            .get();
}

？ .from()工厂方法在此接受MessageSources工厂，您使用.file()工厂方法等等。
