InfoQ Java Queue

published March 18, 2020

This example demonstrates Micronaut Data using SQL/JDBC and is adapted from the example-jdbc example offered by Micronaut Data.

Example Structure

• src/main/java/org/redlich/movies/domain - Entities that map onto database tables.
• src/main/java/org/redlich/movies/repositories - Micronaut Data Repository interfaces.
• src/main/java/org/redlich/movies/controllers - Controllers that are injected with the repository interfaces.
• src/test/java/org/redlich/movies - JUnit 5 tests that test the application.

Example Configuration

The example is configured to use an in-memory H2 database via src/main/resources/application.yml.

The schema is set to generate automatically using the schema-generate: CREATE_DROP setting.

Query logging is enabled in src/main/resources/logback.xml via:

<logger name="io.micronaut.data.query" level="debug" />

Running the example

You can run the tests with either ./gradlew test for Gradle or ./mvnw test for Maven.

The application can be run with either ./gradlew run or ./mvnw compile exec:exec.

Alternatively you can import the example into either IntelliJ, Visual Studio Code or Eclipse.

$ curl -w "\n" http://localhost:8080/movies/The%20Green%20Mile
