The Jdbi library provides convenient, idiomatic access to relational databases in Java and other JVM technologies such as Kotlin, Clojure or Scala.
The Jdbi library provides convenient, idiomatic access to relational databases in Java.
Jdbi is built on top of JDBC. If your database has a JDBC driver, you can use Jdbi with it.
Also check out the code examples in the Examples module.
Prerequisites
Jdbi 3 requires Java 8 or better to run. Jdbi 3 requires Java 11 or better to compile.
We run CI tests against Java 11 and 17 and still support Java 8 for testing on a best-effort basis.
Java 8 compatibility
Java 8 is considered deprecated. While Jdbi does not (yet) have a specific date to drop support, please chart your path forward to a supported JDK! We recommend running the latest LTS JDK.
Jdbi 3 is compiled to Java 8 byte code and is considered stable on Java 8.
However, we now require Java 11 or better to compile as the tool chain no longer runs on Java 8.
We run CI tests on Java 8 on a best effort basis as some of the tests require Java 11+ only dependencies.
NOTE: to run on Java 8, you may need to manage the caffeine
dependency back to the
latest 2.x release. 3.x is necessary for newer JDKs but does not run on 8.
Building
Jdbi is built with Apache Maven, requiring version 3.6.0 or newer.
$ ./mvnw clean install
The unit tests use Postgres and H2 databases (the tests will spin up temporary database servers as needed).
Docker requirements
For a full release build, docker or a docker compatible environment must be available. A small number of tests (those supporting the OTJ postgres plugin) use testcontainers which in turn requires docker.
Local builds can use -Dno-docker
on the command line to skip these tests.
Supported configurations are
- Docker Desktop on MacOS
- docker-ce on Linux
- podman 3 or better on Linux.
For podman, the podman socket must be activated (see https://stackoverflow.com/questions/71549856/testcontainers-with-podman-in-java-tests) for details. SELinux sometimes interferes with testcontainers, if SELinux is active, make sure that there is an exception configured.
Contributing
Please read CONTRIBUTING.md for instructions to set up your development environment to build Jdbi.
