[Solved] logback log format adjustment error: Failed to create converter for [%M] keyword

Adjust the log format of logback, and the program starts to report an error.

before fixing:

    <property name=”logLayout” value=”%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{10} :%-3L – %msg %X{span} %n”/>

adjusted:

   <property name=”logLayout” value=”%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger.%M\(%L\) – %msg %n” />

Error after adjustment:

Failed to create converter for [%M] keyword

 

The content of the logback-spring.xml file after format adjustment, before the format adjustment, the program is normal, and an error is reported after the adjustment.

Solution:

Replace all placeholders ${logLayout} with log format content without placeholders

${logLayout} is replaced by %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger.%M\(%L\) – %msg %n
