使用Java DSL从文件轮询-添加Files.inboundAdapter时发生编译错误

尚不清楚您的IDE中发生了什么，但是我们在测试用例中有以下示例：

@Beanpublic IntegrationFlow fileToFile() {    return IntegrationFlows.from(Files.inboundAdapter(new File("/tmp/in"))         .autoCreateDirectory(true)         .patternFilter("*.txt"), e -> e.poller(Pollers.fixedDelay(5000))) .transform(Transformers.fileToString()) .transform("payload.replaceAll('rn', 'n')") .handle(Files.outboundAdapter("'/tmp/out'")         .autoCreateDirectory(true)) .get();}

这

fixedDelay()

fixed-interval
