This is a simple REST service that uses Spring Boot. I created it to keep track of my weight. I weigh myself each day, and have a web page on my local intranet that invokes this REST service to store the value. The REST service also keeps track of monthly and yearly averages. The data is stored in a Postgresql database.
This is a Maven project, so assuming you have Maven installed, you can just clone the project to your machine and run
mvn install
I run this as a standalone jar. You need to specify the username and password for your database as properties on the command line.
