如何在Mulesoft中实现IF [英] How do I implement IF in mulesoft

问题描述

我想在Mulesoft流程中做出决定，并研究了Choice Flow Control.我的问题是，如果条件为真，我想做某事，如果条件为假，我什么都不做，就像这样:

I want to make a decision in a Mulesoft flow, and have looked at the Choice Flow Control. My problem, is that I want to do something if the condition is true, and nothing if it is false, something like:

if (condition == true)
   do some work

或者，在可能不正确的xml中:

or, in probably incorrect xml:

<choice doc:name="call a subflow if the test is true">
    <when expression="#[flowVars.someVariable == True]">
        <flow-ref name="doSomething" doc:name="do another thing"/>
    </when>
</choice>

没有else子句，也没有默认流程.如何在Mulesoft流程中实现这一点?我可以作弊，然后将日志记录调用添加到默认流中，但我不希望这样做.

no else clause, and no default flow. How is this implemented in a Mulesoft flow? I could cheat, and throw a logging call into a default flow, but I would prefer not to.

推荐答案

不幸的是，Mule中没有简单的"if"处理器.暂时要选择假人，否则要使用路由或过滤器.

Unfortunately there is no simple 'if' processor in Mule. Choice with a dummy otherwise route or filters are the way to go for now.

此处对此进行了很好的讨论: https://www.mulesoft.org/jira/browse/MULE-6129 .这进一步链接到可能的增强功能，例如if/detour路由器.

There is a good discussion on this here: https://www.mulesoft.org/jira/browse/MULE-6129. THis has further links to possible enhancements such as an if/detour router.

M子4更新

在m子4中，您现在可以定义选择路由器，而无需否则路由.并且过滤器不再存在

In mule 4, you can now define a choice router with no need for an otherwise route. And filters no longer exist
