This is a small and simple Spring Boot application that demonstrates how Hibernate events can be used for data change detection. The application is a REST API that performs CRUD operations on an in-memory h2 database using Hibernate. The application consists of a couple of custom Hibernate event listeners that are registered with Hibernate via Spring bootstrapping. In this simple example, the event listeners print details of insert and update events to the standard output. In order to make the event handling asynchronous, the listeners perform their actions in separate threads.
You can run this application in different ways, depending on your preference and your system configuration.
If you have Java and Maven installed, you can run the application using the Maven Spring Boot plugin. Execute mvn spring-boot:run
You can build a Docker image for the application and run it as a Docker container.
- To build the container image, execute
docker build -t hibernate-events-example:1.0 . - To run the container, execute
docker run -p 8080:8080 hibernate-events-example:1.0
You can simply use my pre-built Docker image to run the application, you won't need to build this repo.
Execute docker run -p 8080:8080 psinghal04/hibernate-events-example:1.0
Once you have the application up and running, you can use the included Postman tests collection to run some test CRUD operations on the API and see the event listeners in action.
