Install MariaDB Connector/R2DBC (Spring Data)

Overview

Spring Data R2DBC and MariaDB Connector/R2DBC are usually installed using Maven.

It should also be possible to install Spring Data R2DBC and MariaDB Connector/R2DBC by downloading the JAR files. Because Spring Data R2DBC has many dependencies we recommend using Maven, so that dependencies can be resolved by Maven.

Install MariaDB Connector/R2DBC via Maven

1. To install Spring module for R2DBC, add the spring-boot-starter-data-r2dbc package dependency to your application's pom.xml file:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-r2dbc</artifactId>
   <version>3.3.5</version>
</dependency>

1. Since spring boot 3.0, the MariaDB connector is defined as a possible dependency. So setting dependency just needs:

<dependency>
    <groupId>org.mariadb</groupId>
    <artifactId>r2dbc-mariadb</artifactId>
</dependency>

1. For spring boot before 3.0, a connector compatible with the R2DBC 0.9.1 spec needs to be set in place of org.mariadb:r2dbc-mariadb (be careful not to have any org.mariadb:r2dbc-mariadb dependency set):

<dependency>
    <groupId>org.mariadb</groupId>
    <artifactId>r2dbc-mariadb-0.9.1-spec</artifactId>
    <version>1.2.2</version>
</dependency>

1. To build your application, run Maven:

$ mvn package

During the build process, Maven downloads and installs MariaDB Connector/R2DBC and other dependencies from the relevant repositories.
