Spring Data REST - registering a Jackson module for serialization

[halcyon22]

I have a working project based on the Spring Data REST example project, and I'm trying to do custom serialization using a Jackson module based on the wiki page.

Here's my Jackson module:

public class CustomModule extends SimpleModule {
    public static Logger logger = LoggerFactory.getLogger(CustomModule.class);

    public CustomModule() {
        super("CustomModule", new Version(1, 0, 0, null));
    }

    @Override
    public void setupModule(SetupContext context) {
        logger.debug("CustomModule.setupModule");
        SimpleSerializers simpleSerializers = new SimpleSerializers();
        simpleSerializers.addSerializer(new CustomDateTimeSerializer());
        context.addSerializers(simpleSerializers);
    }

}

The wiki page says:

Any Module bean declared within the scope of your ApplicationContext will be picked up by the exporter and registered with its ObjectMapper.

I'm still pretty new to Spring, so I might just be putting my module bean definition in the wrong place; currently it's in src/main/resources/META-INF/spring-data-rest/shared.xml, which is imported from repositories-export.xml:

<bean id="customModule" class="org.hierax.wpa.schema.mapping.CustomModule" />

I don't see the log statement in setupModule, but I do see log output for other classes in the same package.

I'm using Spring Data REST 1.0.0.RC2.

I've updated to Spring Data REST 1.0.0.RELEASE with JavaConfig, and I got my custom serializer working with the addition of @Component on the custom module.

@Component
public class CustomJacksonModule extends SimpleModule {
	
	public CustomJacksonModule() {
		super("CustomJacksonModule", new Version(1, 0, 0, null));
	}

	@Override
	public void setupModule(SetupContext context) {
		SimpleSerializers simpleSerializers = new SimpleSerializers();
		simpleSerializers.addSerializer (new CustomDateTimeSerializer());
		context.addSerializers(simpleSerializers);
	}

}
