Question

我正在尝试在Mule中选择分支以http.query.params中的参数数量分支吗？
如何将MULE_JDBC_UDATE_COUNT变量的值返回给客户端？

我的config.xml

是的，这可能是#[message.inboundProperties['http.query.params']['myQueryParamName']]之类的。请务必在表达式周围使用#[ ]，并使用“＆amp;＆amp;”和'||'用于布尔运算。
```
<when expression="#[message.inboundProperties['dreifing'] != null &amp;&amp; message.inboundProperties['dags'] != null || message.inboundProperties['dags'] != null]"> 
```
这个表达式的部分似乎也缺少括号。

使用set-payload：

<set-payload value="#[flowVars['MULE_JDBC_UDPATE_COUNT']]" />
