Spring boot application deployment fails with JNDI warnings when custom logback-spring.xml included

Question

Spring boot application deployment fails with JNDI debub messages when custom logback settings file (logback-spring.xml) included. This happens only in linux environment and in windows environment application runs without any issue even though same debug message are shown.

Few of long list of debug messages

15:33:22.537 [https-jsse-nio-8443-exec-70] DEBUG org.springframework.jndi.JndiTemplate - Looking up JNDI object with name [java:comp/env/logging.exception-conversion-word]

What should I do to overcome this?

Answer 1

Try just change logback-spring.xml to logback.xml .

In that case Spring Boot don't configure logback with its templates ( like mentioned here ).

All messages about JNDI names should just gone - like logback autoconfiguraton features in Spring Boot.

Answer 2

I had the same problem and if you change logback-spring.xml to logback.xml this traces will dissapear from the console, BUT they will be written in the ".log" file. I dont know exactly how to delete them from both console and log file, but at least you can choose
