/quarkus-hibernate-maven/README.md: -------------------------------------------------------------------------------- 1 | # Example service (Quarkus + Hibernate) 2 | 3 | ## Prerequisites 4 | 5 | This project requires OpenJDK 17 and Apache Maven for its build. 6 | 7 | ## Build 8 | 9 | Run the following to build the project: 10 | 11 | ```shell 12 | cd user-service 13 | mvn clean verify 14 | java -Dquarkus.http.port=8082 -jar target/quarkus-app/quarkus-run.jar 15 | ``` 16 | 17 | This starts the "user" service, which is accessed by the example service within one of the regression scenarios. 18 | Then build the example service itself: 19 | 20 | ```shell 21 | cd example-service 22 | mvn clean verify 23 | ``` 24 | 25 | In each test class, there's a method `...Regression()` which is commented out. 26 | When commenting it in, this test should fail due to a performance "regresssion", 27 | e.g. due to higher memory allocation than expected, more IO, or more SQL statements. 28 | 29 | [JMC Agent](https://developers.redhat.com/blog/2020/10/29/collect-jdk-flight-recorder-events-at-runtime-with-jmc-agent) is used in the `TodoResourceSqlStatementsTest` 30 | for emitting JFR events from Hibernate / its connection pool. 31 | As JMC Agent isn't available as a Maven dependency on Maven Central, 32 | it is retrieved using the `download-maven-plugin` from the https://github.com/adoptium/jmc-overrides/releases[Adoptium JMC Overrides project]. 33 | 34 | ## Running in the IDE 35 | 36 | When running the `TodoResourceSqlStatementsTest` in your IDE, make sure to specify the correct JMC Agent configuration, 37 | as seen in the _example-service/pom.xml_ file. 38 | 39 | ## Running the Application 40 | 41 | For manual testing, build the application, start a separate Postgres instance via Docker Compose and launch the app like so: 42 | 43 | ```shell 44 | docker-compose up 45 | cd example-service 46 | clean verify -DskipTests=true 47 | java -jar ./examples/example-service/target/quarkus-app/quarkus-run.jar 48 | 49 | # Testing, e.g. via httpie 50 | http POST localhost:8080/todo title=Test priority=2 completed=true 51 | ``` 52 |
