== Spring Data Jpa - GraalVM native image
This example compiles a basic Spring Data Jpa application into a GraalVM native image.
=== Install GraalVM & native image tooling
Download and install GraalVM using https://sdkman.io/[SDKMAN!].
```
$> sdk install java <recent version>.r17-grl
$> gu install native-image
```
=== Compile to native image
The maven build uses a dedicated profile `native` to trigger the native image creation.
```
$> maven clean package -P native
```
This will create the native executable in the target folder.
=== Run the image
Run the image directly from your console as shown below.
This will print results of crud functions invoked via a `CommandLineRunner`.
```
$> ./target/spring-data-jpa-graalvm-native
