Java 从Camel文件组件开始

我刚刚开始使用Camel，我正在试用文件组件。我想递归地处理目录中的每个文件。我试图从（“文件：”）链接到处理器，但我不明白为什么它不工作。在跟踪中，我可以看到驼峰上下文启动了路由

public static void main(String[] args) throws Exception {
    System.out.println("Starting camel");
    final CamelContext camelContext = new DefaultCamelContext();
    camelContext.addRoutes(new RouteBuilder() {
        @Override
        public void configure() throws Exception {
            from(
                    "file://Users/abc123/Documents?recursive=true&noop=true&idempotent=true")
                    .process(new Processor() {

                        public void process(Exchange exchange)
                                throws Exception {
                            System.out.println("exchange=" + exchange);
                        }
                    });

        }
    });
    camelContext.setTracing(true);
    camelContext.start();

    Runtime.getRuntime().addShutdownHook(new Thread() {
        public void run() {
            try {
                camelContext.stop();
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
    });

    Thread.currentThread().join();
}

以下是日志跟踪：

请确保指定文件夹的正确路径。最好的方法是指定绝对路径：

"file:/Users/abc123/Documents?recursive=true&noop=true&idempotent=true"

---

您可以使用相对路径，但要确保它确实是应用程序当前工作目录的相对路径。

试试绝对文件路径。也许这只是一个不同的相对路径。@DraganBozanovic，我使用的是绝对路径。

//Users/abc123/Documents

和

Users/abc123/Documents

都不是绝对路径。是的，你是对的。我用一个斜杠（/）替换了双斜杠（/），它开始工作了。是的，我刚才在下面的答案中建议这样做。
