Question

我正在阅读 Mule in Action 一书以了解response phase。作者说：

Finally, the last thing to consider is that the outcome of the response phase is ignored if the flow response is returned via reply-to routing.

我不太了解。谁能让我理解它？提前谢谢。

Answer 1

这是一个例子。这里请求 - 应答路由器将添加一个replyTo头，因此流'replyto'的结果被发送回'replytoout'队列。它将在请求阶段结束时返回结果，而不会调用响应阶段。

如果你运行它，你应该看到以下记录：

最终价值::: B

而不是'C'，因为忽略了响应阶段

<flow name="replytotest">
        <poll frequency="60000">
            <logger level="INFO" message="Starting" />
        </poll>

        <set-payload value="A" />

        <request-reply>
            <vm:outbound-endpoint address="vm://replytoin" />
            <vm:inbound-endpoint address="vm://replytoout" />
        </request-reply>

        <logger level="INFO" message="Final value::: #[payload] " />
    </flow>

    <flow name="replyto">
        <vm:inbound-endpoint address="vm://replytoin" />

        <set-payload value="B" />

        <response>
            <set-payload value="C" />
        </response>
    </flow>

Mule响应阶段什么时候会被忽略？
