This project offers some of the test data generators i wrote as micro serices via http. One can use it either by just creating and starting the jar file by issuing the command
mvn compile package
and then starting the resulting monolithic jar file by issuing
$JAVA_HOME/bin/java -jar target/generator-microservices-<version>-jar-with-dependencies.jar
Alternatively one could just start the server using maven by issuing
mvn compile exec:java
In both cases, the server starts on port 7000 - just point your browser to it and you see an overview of available generators together with their paths and possible parameters.
However the recommended mode of using this is to use the provided Dockerfile and docker-compose.yml file in src/main/resources. It is probably better to actually use a proxy solution like traefik (the docker-compose is already prepared for this) or similar solutions so the services are actually accessible with a sound hostname and some default port.
