Spring Boot - Logging

You configured logging.level.com.example=TRACE but your logs still show only WARN and above. What is a possible reason?

ATRACE level is not supported by Spring Boot.

BThe package name is incorrect in the configuration.

CThe logging framework's configuration file (e.g., logback.xml) sets a higher threshold.

DSpring Boot disables TRACE logs by default.

Step-by-Step Solution

Solution:

Step 1: Understand interaction with logging framework
Spring Boot delegates to frameworks like Logback which have their own config files.
Step 2: Check for framework-level overrides
If logback.xml sets root or package level to WARN, it overrides Spring Boot properties.
Final Answer:
The logging framework's configuration file (e.g., logback.xml) sets a higher threshold. -> Option C
