如何在使用bean引用的java中设置路由

我正在尝试设置以下路线:

  @Override
    public void configure() throws Exception {
        log.info("Creating ftp rout from " + config.ftpUrl().split("\\?")[0]);
        from(config.ftpUrl()
             + "&stepwise=true"
             + "&delay=1000"
             + "&move=${file:name}.trans"
             + "&recursive=true"
             + "&binary=true"
             + "&filter=#" + Beans.doneFilter.name()
             + "&maxMessagesPerPoll=200"
             + "&eagerMaxMessagesPerPoll=false"
             + "&sorter=#" + Beans.sorter.name())
                                                     .log("Downloading file ${file:name}")
                                                     .to("file:" + config.ftpTargetPostpaid())
                                                     .to("file:" + config.ftpTargetPrepaid())
                                                     .to("file:" + config.ftpTargetFonic())
                                                     //.routePolicyRef(Beans.policy.name())
                                                     .autoStartup(false)
                                                     .routeId("ftp");
    }

错误是:

  

无法为属性找到合适的setter:filter as asnn&t; t   具有相同类型的setter方法:java.lang.String和类型转换   可能:没有类型转换器可用于转换类型:   java.lang.String到所需的类型:   带有值的org.apache.camel.component.file.GenericFileFilter   #doneFilter

我认为我引用绑定bean的方式是错误的?我以这种方式绑定所有bean(独立应用程序):

public class MainApp {

/**
 * A main() so we can easily run these routing rules in our IDE
 */
public static void main(String... args) throws Exception {
    Injector i = Guice.createInjector(new CepModule());
    Main main = new Main();
    bindBeans(main);
    main.enableHangupSupport();
    main.addRouteBuilder(i.getInstance(FetchFtp.class));
    main.run();

}

private static void bindBeans(Main main) {
    for (Beans bean : Beans.values()) {
        main.bind(bean.name(), bean.clazz());
    }
}

/**
 * This is the java style bean registry. Use the enums name as reference to the bean.
 * 
 *
 */
public static enum Beans{
    sorter(SortingStrategy.class),
    policy(PolicyForStartAndStopRoutes.class),
    doneFilter(ExcludeDoneFilesFilter.class);

    private final Class<?> clazz;

    Beans(Class<?> clazz){
        this.clazz = clazz;;
    }

    public Class<?> clazz(){
        return clazz;
    }
}

}

那么如何在java中配置的路由中使用bean / classes?

Camel不仅要求class引用,还要求bean实例。

假设类具有默认构造函数,请将bean.clazz().newInstance()绑定到注册表而不是bean.clazz(),i。 E:

main.bind(bean.name(), bean.clazz().newInstance());
