骆驼初体验 [英] Camel first experience

问题描述

我对 Apache Camel 很陌生.我无法让最简单的 Camel 示例工作.代码如下:

I'm very new with Apache Camel. I can't get the simplest Camel example working. Here is the code:

public class CamelFE {
  public static void main(String[] args)  {
    CamelContext cc = new DefaultCamelContext();
    cc.addRoutes(new RouteBuilder() {
      @Override
      public void configure() throws Exception {
        System.out.println("Go!");
        from("file://Users/Foo/Desktop/IN")
        .to("file://Users/Foo/Desktop/OUT");

    });
  }
  cc.start();
  cc.stop();
}

两个目录都存在，在from中只有一个简单的文件，helo.txt.路由开始并显示 Go! 消息，但没有文件被移动到 to 目录.我错过了什么?

Both directories exists, in the from one there is one simple file, helo.txt. The route starts and Go! message is displayed but no file was moved to the to directory. What am I missing?

这是控制台输出.<代码>SLF4J:无法加载类org.slf4j.impl.StaticLoggerBinder".SLF4j:默认为无操作 (NOP) 记录器实现SLF4J:有关更多详细信息，请参阅 http://www.slf4j.org/codes.html#StaticLoggerBinder去吧！

推荐答案

我猜您正在使用 Windows，因为您引用了 Users/.../Desktop.如果是这种情况，则您的文件语法略有偏差.您应该拥有 file:///Users/Foo/Desktop 而不是 file://Users/Foo/Desktop.

I'm guessing you're using Windows, since you have references to Users/.../Desktop. If that's the case, your file syntax is slightly off. Rather than file://Users/Foo/Desktop, you should have file:///Users/Foo/Desktop.

您还需要在应用程序终止之前留出足够的时间进行处理.您可以添加一个 Thread.sleep.请注意，在网络应用程序中，这不会成为问题，因为应用程序会保持运行.

You also need to allow enough time for the processing to occur before the application terminates. You might add a Thread.sleep. Note that in a web application, this wouldn't be an issue as the app stays running.

public class CamelFE {
    public static void main(String[] args) throws Exception {
        CamelContext cc = new DefaultCamelContext();
        cc.addRoutes(new RouteBuilder()
        {

            @Override
            public void configure() throws Exception {
                System.out.println("Go!");
                from("file:///Users/Foo/Desktop/IN").to("file:///Users/Foo/Desktop/OUT");
            }
        });

        cc.start();
        Thread.sleep(10000);
        cc.stop();
    }
}
