我正在尝试使用 fuse esb + apache camel + seda/activemq 公开 Web 服务，但我遇到了将状态消息返回给 Web 服务调用的问题。

这是我的简单骆驼路线：

<?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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
    http://camel.apache.org/schema/cxf http://camel.apache.org/schema/cxf/camel-cxf.xsd">

    <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进行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.

堆栈跟踪原因：

Caused by: org.apache.camel.ExchangeTimedOutException: The OUT message was not received within: 30000 millis. Exchange[Message: $CONSOLE:DISPLAY,test]

我使用 seda 或 activemq 作为消费者有相同的结果，但它适用于文件消费者。

我在 apache-servicemix-4.4.1-fuse-02-05 版本上。

知道我做错了什么吗？谢谢你的帮助

当您使用将消息发送到 seda 端点时

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

并且消息来自网络服务，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”，从某种意义上说它会等待消息待处理。但是由于未处理消息，因此触发了 30 秒的超时，以及您看到该异常的原因。查看超时选项：http ://camel.apache.org/seda

相反，您似乎想尽快将 OK 消息发送回 Web 服务，同时将消息发送到队列以进行异步进一步处理。有一个 EIP 和它的 WireTap EIP。所以改用它：https ://camel.apache.org/components/3.4.x/eips/wireTap-eip.html

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

要解决此问题，您可以增加超时值，或者您可以使用 0 或负值禁用超时。

如何禁用超时？

答案：“seda:someName?timeout=0”

设置 timeout=0 后，您将不会遇到超时错误。
