log4j2.xml configurations are not reflected in spring boot application - spring

Question

I am trying to setup a project with spring boot. Although I have defined all the dependencies for log4j, and added the log4j2.xml configuration file, the logs printed doesn't have the pattern defined in xml file. I checked the external libraries pulled by maven, and I see logback dependencies, which are not in my pom, I have even added exclusions. I am using spring boot 3 with Java 17. I have also tried excluding spring-boot-starter-logging. Nothing seems to work.
Here is the pom.xml file
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

I have noticed that your "pom.xml" doesn't include org.springframework.boot:spring-boot-starter dependency, which is the core Spring Boot Starter.
Try adding it and add exclusion to "org.springframework.boot:spring-boot-starter-logging" from that dependency
