Mule 响应阶段什么时候会被忽略？

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.

不是很懂。任何人都可以让我理解它吗？提前致谢。

Answer 1

这是一个例子。这里 request-reply 路由器将添加一个 replyTo header，因此流 'replyto' 的结果被发送回 'replytoout' queue。它将到达请求阶段的末尾，然后 return 结果而不调用响应阶段。

如果你运行这你应该看到以下记录：

Final value::: 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>
