μjUniter: Automated Unification of Microservices into Monoliths

Reproducibility package for ASE 2024.

A tool for automating the migration from Java Spring-Boot microservice systems to monolith systems.

/mjuniter is the main research product. Can be packaged with mvn and then run with java. The output monolith can be run with mvn spring-boot:run or as a container after proper configurations are made.

/rmgenerator is the synthetic microservice generator. Can be packaged with mvn and then run with java. Output microservices can be packaged with maven, and deployed as containers with docker.

gucc.py is a python script used to automate some of the building and testing pipeling for the synthetically generated microservices. It generates, unites, compares the lines of code, and compiles the tools. It depends on the presence of the CLOC executable availabl on windows at https://github.com/AlDanial/cloc.

The microservice systems generated by rmgenerator can get very large and were not included as they can be easily reproduced.

The third party example is available at https://github.com/piomin/sample-spring-microservices-new/tree/master/organization-service/src/main/java/pl/piomin/services/organization.
