Building and Running Application¶
There are several approaches to building and running the application.
Using IDE¶
In an IDE, such as IDEA, it is easy to use the IDE built-in tools to build or rebuild the whole project. Most of modern IDEs include incremental building for code changes automaticially.
To run the application, open the entry class Application, click and run it directly like running a Java application.
Using Command Line¶
If it is a Maven project, open terminal and run mvn clean package in the project root folder to build the application into a jar archive.
$ mvn clean package
Then run the build application.
$ java -jar target/demo.jar
If you prefer Gradle as the build tools, use the following commands instead.
$ ./gradle build
$ java -jar build/demo.jar
Setup Database¶
In the root folder of the sample codes repository, there is a prepared Docker Compose file, which is used to serve required external service when building and running the sample applications, including Postgres, Mongo, etc.
For example, run the following command to bootstrap a Postgres database instance in Docker.
$ docker compose up postgres
