Question

我正在使用apache camel 2.12.1创建一个路由，然后在我的本地目录中移动一些文件，exmple运行正常，但文件永远不会被移动，这是该类的代码。

public class MoveFilesTest {
    private static final Log LOG = LogFactory.getLog(MoveFilesTest.class);

    public static void main(String args[]) throws Exception {
        LOG.debug("create CamelContext");
        CamelContext context = new DefaultCamelContext();

        // add our route to the CamelContext
        context.addRoutes(new RouteBuilder() {
            File file = null;
            public void configure() {
                from("file:data/inbox?delay=100&noop=true")
                .process( new Processor() {

                    public void process(Exchange msg) throws Exception {
                        File file = msg.getIn().getBody(File.class);
                        LOG.debug("Processing file: " + file.getName());

                    }
                })

                .to("file:data/outbox").end();
            }
        });

        LOG.debug("start the route and let it do its work");
        context.start();

        context.stop();

    }
}

作为一个注释，这段代码只是为了工作，现在我正在使用mac os x 10.7，这是调试日志。我添加了noop = false和delete = true，但结果是一样的。谢谢

Answer 1

是的，你启动Camel并立即停止它。因此，当您将文件放入文件夹时。它不会处理因为骆驼已经停止了。

Camel包含Main实现，以保持Camel在独立应用程序中运行。

Answer 2

CamelContext.start没有阻止，所以基本上你是在启动上下文然后立即停止它。您需要等待或阻止某些事情，直到上下文停止。您可以参考this thread了解某些方法。

Answer 3

我有一个类似的问题，但这与streamCaching（）没有正确设置，所以下面的代码失败

    context.getStreamCachingStrategy().setSpoolDirectory(spoolDirectory);
    from(uri.toString()).streamCaching().to(destination);

我直接在CamelContext上设置Streaming并解决了问题

    CamelContext context = getContext();
    context.setStreamCaching(true);
    context.getStreamCachingStrategy().setSpoolDirectory(localSpoolDirectory);
    context.getStreamCachingStrategy().setSpoolThreshold(Long.parseLong(spoolThreshold.trim()));
    context.getStreamCachingStrategy().setBufferSize(Integer.parseInt(bufferSize.trim()));

Apache camel文件组件不移动文件
