Anypoint Studio Mule의 사용자 정의 예외 메시지에 새 행 추가

Question

Anypoint Studio 6.1 및 Mule 3.8.1을 사용하고 있고 "\ n"이 새 행으로 반환 된 예외 메시지를 반환하고자합니다. System.getProperty ("line.separator")를 사용하려고하는데 "\ n"이 메시지에 텍스트로 표시되고 새 줄이 표시되지 않습니다.

어떻게 작동합니까?

XML 테스트 흐름 : 당신은 개행 문자를 이스케이프 할 필요가 같은

보인다. . 또한, 작은 따옴표 (') 대신에 MEL 발현 내부에 큰 따옴표 (")를 사용

<logger message="#[payload.replace('\\n', System.getProperty('line.separator'))]" level="INFO" 
     doc:name="Logger" /> 
    <set-payload value="#[payload.replace('\\n', System.getProperty('line.separator'))]" encoding="UTF-8" 
     mimeType="application/json" doc:name="Set Payload" /> 

위의 코드가 작동하는 것 같다 :.
