JSR-303 activation in jsonschema2pojo

Question

There is a place in jsonschema2pojo documentation describing possibility to enable JSR-303 annotations generation. If I understand correctly it can be done via Maven plugin configuration. Could someone show how to accomplish it, which tag in plugin configuration should be used? Thanks to all!

Answer 1

I think you are looking for the includeJsr303Annotations parameter. See the plugin documentation:

includeJsr303Annotations

Whether to include JSR-303 annotations (for schema rules like minimum, maximum, etc) in generated Java types. Schema rules and the annotation they produce:

• maximum = @DecimalMax
• minimum = @DecimalMin
• minItems, maxItems = @Size
• minLength, maxLength = @Size
• pattern = @Pattern
• required = @NotNull

Any Java fields which are an object or array of objects will be annotated with @Valid to support validation of an entire document tree.

• Type: boolean
• Since: 0.3.2
• Required: No
• Expression: ${jsonschema2pojo.includeJsr303Annotations}
• Default: false

It can be used as following:

<plugins>
    <plugin>
        <groupId>org.jsonschema2pojo</groupId>
        <artifactId>jsonschema2pojo-maven-plugin</artifactId>
        <version>0.4.27</version>
        <configuration>
            <sourceDirectory>${basedir}/src/main/resources/schema</sourceDirectory>
            <targetPackage>com.example.types</targetPackage>
            <includeJsr303Annotations>true</includeJsr303Annotations>
        </configuration>
        <executions>
            <execution>
                <goals>
                    <goal>generate</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>
