org.apache.camel.ExchangeTimedOutException：未收到OUT消息：30000毫秒

我正在尝试使用fuse esb + apache camel + seda / activemq公开一个Web服务，我正面临一个将状态消息撤回到Web服务调用的问题。

这是我简单的骆驼路线：

<?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:cxf="http://camel.apache.org/schema/cxf"

    <cxf:cxfEndpoint id="msgInEndpoint" address="http://localhost:9000/msgin/"
        serviceClass="com.test.jaxws.MsgInEndpoint">
    </cxf:cxfEndpoint>

    <camelContext xmlns="http://camel.apache.org/schema/spring">
        <route id="control">
            <from uri="cxf:bean:msgInEndpoint" />
            <to uri="log:incomingMsgIn" />
            <to uri="seda:OpCon.MSGIN" />
            <transform>
                <constant>OK</constant>
            </transform>
        </route>
    </camelContext>
</beans>

当我使用soapUI执行Web服务请求时，会出现超时问题：

Exhausted after delivery attempt: 1 caught: org.apache.camel.ExchangeTimedOutException: The OUT message was not received within: 30000 millis.

stacktrace原因：

我使用seda或activemq作为使用者获得相同的结果，但它适用于文件使用者。

我正在使用apache-servicemix-4.4.1-fuse-02-05版本。

知道我做错了什么吗？ 谢谢你的帮助

答案 0 :(得分：7)

使用

将消息发送到seda端点时 
<to uri="seda:OpCon.MSGIN" />

消息源自Web服务，然后消息使用InOut作为消息交换模式（例如请求/回复），这意味着Camel期待来自seda队列的'回复'，在某种意义上它将等待用于处理消息。但由于未处理消息，因此会触发30秒的超时，以及为什么会看到该异常。请参阅：http://camel.apache.org/seda

上的超时选项

相反，您似乎希望尽快向Web服务发回OK消息，同时向队列发送消息以进行异步进一步处理。有一个EIP，它的WireTap EIP。所以请改用：http://camel.apache.org/wire-tap 

<wireTap uri="seda:OpCon.MSGIN" />

答案 1 :(得分：0)

要解决此问题，您可以增加超时值，或者只使用0或负值来禁用超时。

如何禁用超时？

Ans：“seda：someName？timeout = 0”

设置超时= 0后，您将不会遇到超时错误。
