我尝试用MyRouteBuilder中的configure（）上的endpoint调试它，错误出现在断点之前。

下面是configure（）方法，它相当繁重：

public class MyRouteBuilder extends RouteBuilder {
private ConnectorEndPoint src;
private ConnectorEndPoint dest;

int i = 0;
private String CRON_EXPRESSION_QUARTZ = CRONGenerator.generateCRONExpression("0/1", "9-17", "?", "*", "MON-FRI");

private MyProcessor processor = new MyProcessor();
RestConsumerFactory consumerFactory = new RestConsumerFactory() {
    public Consumer createConsumer(CamelContext camelContext, Processor processor, String verb, String basePath, String uriTemplate, String consumes, String produces, Map<String, Object> parameters) throws Exception {
        return null;
    }
};

public MyRouteBuilder(ConnectorEndPoint src, ConnectorEndPoint dest) {
    this.src = src;
    this.dest = dest;
}

public void configure() {
    if (src instanceof ConnectorSQL){
        from("quartz2://foo?cron="+ CRON_EXPRESSION_QUARTZ)
        .to(src.getRouteFrom())
        .bean(processor, "conversionNumericAndDate")
        .bean(processor, "standardisation")
        .to(dest.getRouteTo());
    } else if (src instanceof ConnectorMongoDB){
        from("quartz2://foo?cron="+ CRON_EXPRESSION_QUARTZ)
        .to(src.getRouteFrom())
        .bean(processor, "convertDBObjectToString")
        //.bean(processor, "conversionNumericAndDate")
        .to(dest.getRouteTo());
    } else if (src instanceof ConnectorREST){
        from("quartz2://foo?cron="+ CRON_EXPRESSION_QUARTZ).to(src.getRouteFrom())
        //.bean(processor, "conversionNumericAndDate")
        //.bean(processor, "standardisation")
        .to(dest.getRouteTo());
    } else if (src instanceof ConnectorXMLFile){
        XmlJsonDataFormat xmlJsonFormat = new XmlJsonDataFormat();
        xmlJsonFormat.setEncoding("UTF-8");
        xmlJsonFormat.setForceTopLevelObject(true);
        xmlJsonFormat.setTrimSpaces(true);
        xmlJsonFormat.setSkipNamespaces(true);
        xmlJsonFormat.setRemoveNamespacePrefixes(true);         
        from("file:xml?scheduler=quartz2&scheduler.cron="+ CRON_EXPRESSION_QUARTZ)
        .marshal(xmlJsonFormat)
        .to(dest.getRouteTo());
    } else if (src instanceof ConnectorLogsFile){
        ArrayListAggregationStrategy aggregationStrategy = new ArrayListAggregationStrategy();
        from(src.getRouteFrom())
        .bean(processor, "lineFilter(${body}, " + src.getFieldToFilter() +", " + src.getFirstValue() +", " + src.getSecondValue() + ")")
        .split(body().tokenize("\n"))
        .filter().method(MyFilter.class, "isValidError")
        .bean(processor, "processLogsApplicationSource")
        .filter().method(MyFilter.class, "dateFilter(${body}, " + src.getFieldToFilter() +", " + src.getFirstValue() +", " + src.getSecondValue() + ")")
        .aggregate(body(), aggregationStrategy).completionInterval(1000)
        .to(dest.getRouteTo());
    } else {
        System.err.println("Erreur : Type de endpoint en entrée inconnu");
        System.exit(1);
    }
}

因此，这就像骆驼上下文没有启动configure（）方法，因此不会创建RouteBuilder也不会被上下文找到。我的web.xml是：

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.apache.camel.component.servletlistener.SimpleCamelServletContextListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

谢谢你的帮助！

几点建议：

1. 检查RouteBuilderbean是否实际在容器中创建。
2. 您的MyRouteBuilder是否从Camel扩展RouteBuilder？

为了获得更多的澄清，请提供MyRouteBuilder的完整代码和完整的StackTrace。
