This documentation is for the unreleased development version of jOOQ. Click on the above version links to get this documentation for a supported version of jOOQ.

Configuration and setup of the generator

Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition

There are three binaries available with jOOQ, to be downloaded from https://www.jooq.org/download or from Maven central:

jooq-3.20.0-SNAPSHOT.jar
The main library that you will include in your application to run jOOQ
jooq-meta-3.20.0-SNAPSHOT.jar
The utility that you will include in your build to navigate your database schema for code generation. This can be used as a schema crawler as well.
jooq-codegen-3.20.0-SNAPSHOT.jar
The utility that you will include in your build to generate your database schema

Configure jOOQ's code generator

You need to tell jOOQ some things about your database connection. Here's an example of how to do it for an Oracle database

XML (standalone and maven)

Programmatic

Gradle (Kotlin)

Gradle (Groovy)

Gradle (third party)

<configuration>
  <!-- Configure the database connection here -->
  <jdbc>
    <driver>oracle.jdbc.OracleDriver</driver>
    <url>jdbc:oracle:thin:@[your jdbc connection parameters]</url>
    <user>[your database user]</user>
    <password>[your database password]</password>

    <!-- You can also pass user/password and other JDBC properties in the optional properties tag: -->
    <properties>
      <property><key>user</key><value>[db-user]</value></property>
      <property><key>password</key><value>[db-password]</value></property>

See the configuration XSD and gradle code generation for more details.

There are also lots of advanced configuration parameters, which will be treated in the manual's section about advanced code generation features. Note, you can find the official XSD file for a formal specification at:
https://www.jooq.org/xsd/jooq-codegen-3.19.8.xsd

Run jOOQ code generation

Code generation works by calling this class with the above property file as argument.

org.jooq.codegen.GenerationTool /jooq-config.xml

Be sure that these elements are located on the classpath:

jooq-3.20.0-SNAPSHOT.jar, jooq-meta-3.20.0-SNAPSHOT.jar, jooq-codegen-3.20.0-SNAPSHOT.jar, reactive-streams-1.0.3.jar, r2dbc-spi-1.0.0.RELEASE.jar
The JDBC driver you configured

A command-line example (for Windows, OSX/Linux/etc. will be similar)

Put the XML configuration file, jooq*.jar and the JDBC driver into a directory, e.g. C:\temp\jooq
Go to C:\temp\jooq
Run java -cp jooq-3.20.0-SNAPSHOT.jar;jooq-meta-3.20.0-SNAPSHOT.jar;jooq-codegen-3.20.0-SNAPSHOT.jar;reactive-streams-1.0.3.jar;r2dbc-spi-1.0.0.RELEASE.jar;[JDBC-driver].jar org.jooq.codegen.GenerationTool <XML-file>

Note that the XML configuration file can also be loaded from the classpath, in which case the path should be given as /path/to/my-configuration.xml

Run code generation from Eclipse

Of course, you can also run code generation from your IDE. In Eclipse, set up a project like this. Note that:

this example uses jOOQ's log4j support by adding log4j.xml and log4j.jar to the project classpath.
the actual jooq-3.20.0-SNAPSHOT.jar, jooq-meta-3.20.0-SNAPSHOT.jar, jooq-codegen-3.20.0-SNAPSHOT.jar artefacts may contain version numbers in the file names.

Once the project is set up correctly with all required artefacts on the classpath, you can configure an Eclipse Run Configuration for org.jooq.codegen.GenerationTool.

With the XML file as an argument

And the classpath set up correctly

Finally, run the code generation and see your generated artefacts

Integrate generation with Maven

Using the official jOOQ-codegen-maven plugin, you can integrate source code generation in your Maven build process:

<plugin>

  <!-- Specify the maven code generator plugin -->
  <!-- Use org.jooq                for the Open Source Edition
           org.jooq.pro            for commercial editions with Java 17 support,
           org.jooq.pro-java-11    for commercial editions with Java 11 support,
           org.jooq.pro-java-8     for commercial editions with Java 8 support,
           org.jooq.trial          for the free trial edition with Java 17 support,
           org.jooq.trial-java-11  for the free trial edition with Java 11 support,
           org.jooq.trial-java-8   for the free trial edition with Java 8 support

       Note: Only the Open Source Edition is hosted on Maven Central.
             Install the others locally using the provided scripts, or access them from here: https://repo.jooq.org -->
  <groupId>org.jooq</groupId>
  <artifactId>jooq-codegen-maven</artifactId>
  <version>3.20.0-SNAPSHOT</version>

  <!-- The plugin should hook into the generate goal -->
  <executions>
    <execution>
      <goals>
        <goal>generate</goal>
      </goals>
    </execution>
  </executions>

  <!-- Manage the plugin's dependency. In this example, we'll use a PostgreSQL database -->
  <dependencies>
    <dependency>
      <groupId>org.postgresql</groupId>
      <artifactId>postgresql</artifactId>
      <version>42.7.3</version>
    </dependency>
  </dependencies>

  <!-- Specify the plugin configuration.
       The configuration format is the same as for the standalone code generator -->
  <configuration>

    <!-- JDBC connection parameters -->
    <jdbc>
      <driver>org.postgresql.Driver</driver>
      <url>jdbc:postgresql:postgres</url>
      <user>postgres</user>
      <password>test</password>
    </jdbc>

    <!-- Generator parameters -->
    <generator>
      <database>
        <name>org.jooq.meta.postgres.PostgresDatabase</name>
        <includes>.*</includes>
        <excludes></excludes>
        <!-- In case your database supports catalogs, e.g. SQL Server:
        <inputCatalog>public</inputCatalog>
          -->
        <inputSchema>public</inputSchema>
      </database>
      <target>
        <packageName>org.jooq.codegen.maven.example</packageName>
        <directory>target/generated-sources/jooq</directory>
      </target>
    </generator>
  </configuration>
</plugin>

Use jOOQ generated classes in your application

Be sure, both jooq-3.20.0-SNAPSHOT.jar and your generated package (see configuration) are located on your classpath. Once this is done, you can execute SQL statements with your generated classes.
