如何编辑默认骡子错误信息..? [英] How to Edit Default Mule Error message..?
问题描述
我已将Mule HTTP入站端点定义为:
I have defined a Mule HTTP Inbound Endpoint as :
<flow name="jfeed_fill_data">
<http:inbound-endpoint address="http://localhost:1212/jcore/insert/feed/">
</http:inbound-endpoint>
<component class="main.java.com.joshlabs.jcore.Feed"/>
</flow>
现在这项服务工作正常。
Now this Service Works Fine.
但当我输入一个变形的URL,如 http:// localhost:1212 / jcore / insert / feedasdasdAwes / 时,我从MULE收到以下消息:
But When i type a Deformed URL , something like "http://localhost:1212/jcore/insert/feedasdasdAwes/", I get the following Message from MULE :
Cannot bind to address "http://localhost:1212/jcore/insert/feedasdasdAwes/"
No component registered on that endpoint
我的问题是:如何将上述默认消息更改为我自己的消息。 ?
My Question is : How can i Change the above default Message to Something of my own.?
注意:实际上我想将JSON字符串作为错误消息返回。类似于:
{
Exception: "Invalid URL"
}
如果可能,那么可以在上面抛出 HTTP 404:未找到错误case.. ??
And if possible, then "Can MULE throw HTTP 404 : Not Found Error in above case"..??
推荐答案
您只需要让您的端点接受所有子路径,然后使用消息处理错误的路径路由:
You just need to make your endpoint accept all sub-paths and then handle wrong ones with message routing:
<flow name="jfeed_fill_data">
<http:inbound-endpoint address="http://localhost:1212" />
<choice>
<when evaluator="header" expression="INBOUND:http.request.path=/jcore/insert/feed/">
<component class="main.java.com.joshlabs.jcore.Feed"/>
</when>
<otherwise>
<message-properties-transformer>
<add-message-property key="http.status" value="404"/>
</message-properties-transformer>
<expression-transformer>
<return-argument evaluator="string" expression="{Exception: "Invalid URL"}"/>
</expression-transformer>
</otherwise>
</choice>
</flow>
