使用 Java DSL 从文件中轮询 - 添加 Files.inboundAdapter 时编译错误 [英] Polling from file using Java DSL - compile error when adding Files.inboundAdapter

问题描述

我正在使用 Spring Integration Java DSL v. 1.2.2 并按照一些示例尝试编写代码来轮询文件夹

I am using Spring Integration Java DSL v. 1.2.2 and following some examples I try to write a code to poll a folder

    return IntegrationFlows
            .from(Files.inboundAdapter(new File("/tmp/foo")))
            .handle((p, h) -> fileProcessor.process(p))
            .get();

这段代码无法编译，因为

This code can not be compiled because

"Cannot resolve method 'from(org.springframework.integration.dsl.
   file.FileInboundChannelAdapterSpec)'"

如何解决这个问题以及如何添加固定间隔轮询?

How this can be fixed and how fixed-interval polling can be added?

推荐答案

不清楚您的 IDE 中发生了什么，但我们在测试用例中有此示例:

Not clear what's going on in your IDE, but we have this sample in test-cases:

@Bean
public 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('\r\n', '\n')")
            .handle(Files.outboundAdapter("'/tmp/out'")
                    .autoCreateDirectory(true))
            .get();
}

fixedDelay() 是您关于 fixed-interval 的第二个问题的答案.

The fixedDelay() is an answer to your second question about fixed-interval.
