A Spring Boot based Log4j2 starter project

Spring Boot uses Logback as a default logging solution. In order to switch to Log4j2, there are some configurations that has to be made.

The following customized configurations provide the following features:

A Maven POM for a Spring Boot starter project
Logstash layout dependency for JSon log files to feed into ELK
Log4j configuration with MDC support
Log4j configuration produces multiple log files

A Maven Parent POM for a Spring Boot based application

Spring Boot based Java application is a good choice for new Java applications. The Spring Boot eco-system provides numerous libraries and tools.

In order to better manage the versions of huge amount of libraries, it is a good approach to upgrade the libraries along with Spring Boot upgrades. It will save huge maintenance and integration effort by taking advantage of the work Spring Boot team has already done.

The following sample parent POM provides the following customized features:

1. removed the Logback and Appache Commons Logging related dependencies
2. added unit test dependencies
3. enabled resource filtering
4. configured Google stype check
