如何在Mule logger组件的消息正文中插入换行符 [英] How do you insert a newline in message body of mule logger component

问题描述

有人可以告诉我如何在m子记录器组件的消息中插入新行吗?

Can anyone tell me how to insert a new line in the message of a mule logger component?

例如，我在记录器的消息中包含以下内容:

For example, I have the following in the message for the logger:

Payload is: #[payload] 
Inbound Headers:  #[headers:INBOUND:*] 
Outbound Headers:  #[headers:OUTBOUND:*]  
Exceptions:  #[exception]

我想在上述各项之后插入新行.我尝试只在每行的末尾添加\ n，但这没用.

I'd like to insert a new line after each of the above. I've tried just adding \n to the end of each line, but that didn't work.

推荐答案

使用MEL:

    <logger
        message="#['Payload is:'+payload+'\nInbound Headers: '+message.inboundProperties.entrySet()+'\nOutbound Headers: '+message.outboundProperties.entrySet()+'\nExceptions: '+exception]"
        level="INFO" />
