Intentionally setting a Spring bean to null

Question

I\'m using Spring to inject JMS connection factory into my Java application. Since this factory is only required within the production environment, not while I\'m developing

Answer 1

factory-bean/factory-method doesn't work with null, but a custom FactoryBean implementation works fine:

public class NullFactoryBean implements FactoryBean {

    public Void getObject() throws Exception {
        return null;
    }

    public Class getObjectType() {
        return null;
    }

    public boolean isSingleton() {
        return true;
    }
}
