How do you insert a newline in message body of mule logger component

Question

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

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]

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.

Answer 1

Use MEL:

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

Proline

It would still be better to use System.getProperty('line.separator') instead of \n to make it closs-platform. – Forficate

@Forficate Sounds good, but first we would need to make sure that \n isn't already interpreted by MVEL as System.getProperty('line.separator'). – Proline

Answer 2

You could do something like this:

Payload is: #[payload] #[System.getProperty('line.separator')] Inbound Headers: ...

Answer 3

use expression-transformer:

<expression-transformer expression="#[message.payload = message.payload + System.getProperty('line.separator')]" doc:name="Append CRLF"/>

Answer 4

There are a couple of ways to do this:

1) Use: #[System.getProperty('line.separator')]

2) Use: #['\n'] eg: #['Hello\n'+payload+'Welcome to \n new line']

#['\n'] is best and simplest option of all - thank you! – Heffron

Answer 6

//This should work. tested in mule 3.9 CE

<logger message="Payload is #[message.payloadAs(java.lang.String)]  #[System.lineSeparator()]  INBOUND HEADERS =  #[headers:inbound:*]" level="INFO" doc:name="Logger"/>

You can use this syntax with Mule 4:

My Input payload: #["\n"] #[payload]
