Question

我已经安装了camel（版本2.10.X），我可以使用csv和xslt处理器运行很多示例。现在我正在尝试使用骆驼aggregator。我已经从驼峰文档中调整了一个示例，这样当3个文件写入input目录时，它们必须聚合并发送到输出目录

我的背景如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:amq="http://activemq.apache.org/schema/core"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
       http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd
       http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">

<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent" />
<bean id="aggregatorStrategy" class="org.apache.camel.processor.BodyInAggregatingStrategy" />

<camel:camelContext xmlns="http://camel.apache.org/schema/spring">
    <camel:package>com.example.camel.wardemo</camel:package>

    <camel:route>
        <camel:from uri="file:/inputdir" />         
        <camel:aggregate strategyRef="aggregatorStrategy" completionSize="3">           
            <camel:correlationExpression>
                <camel:simple>header.id</camel:simple>
            </camel:correlationExpression>          
            <camel:to uri="file:/outdir" />
        </camel:aggregate>
    </camel:route>
</camel:camelContext>

但是在部署war文件时，应用程序无法启动并导致异常：（localhost_XXXXXX.log

    5.06.2013 18:14:03 org.apache.catalina.core.ApplicationContext log
INFO: Initializing Spring root WebApplicationContext

SCHWERWIEGEND: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

这应该是我在上下文中对此标记的引用：

<bean id="aggregatorStrategy" class="org.apache.camel.processor.BodyInAggregatingStrategy" />

我做错了什么？

谢谢！

修改

问题是BodyInAggregatingStrategy不在camel-core依赖项中，因为它位于/src/test/java ...

之下
